do the cars turn around themselves ?

[Nigo]

... magically when you turn the steering wheel past a certain point, or is it me beeing crazy ?
is it me or even the cleanest drivers can't avoid sliding cars when driving fast ?
is it me or you can take a corner faster sideways ?
is it me or there is no induced understeer at corner entry, no matter how you tune the car ?

Shift feels great somehow, but I can't help thinking that, in the end, there is something very wrong with the car behaviour

 

[Shadow Wulf 2k]

It seems like the handling model has a little bit of "wishfull thinking" in the oversteering direction.

Then again, are you using the default controller sensitivity? The defaults are overly sensitive, and make it easy to turn too much. Dial them back to about 5-10% and it's much easier to drive.

Far too much of the game's behavior is based on the tuning settings of the cars, particularly when the cars are upgraded.

I have some cars in my inventory that feel and drive wonderfully, just as good as any car in my other driving games. They feel that way because the tuning settings (in advanced tuning), are perfect.

That same car with the wrong tuning settings feels like a hovercraft.

Some cars in this game even when upgraded, still feel relatively good with the default tuning settings. Some have to be adjusted to get them just right. Others apparently, can't ever be adjusted so they feel right.

EA marketed this game as a semi-sim or simlike arcade game. I halfway think it's a puzzle game, like Rubik's Cube. Once you figure it out, and it may take a month or more, suddenly you realize it feels really, really good.

This is not a game for the impatient. You have to work on it until it feels right to you. I would venture to say that many of the people who walked away from this game two or three weeks after they got it, just didn't give it enough time and never figured out the tuning puzzle.

 

[boxox]

They don't turn around themselves. Most cars have a 30-something component suspension model where every individual piece is weighted and constrained as the real car is. The fuel tank is a separately located piece that affects COG. The tyres are 3d objects that move and distort according to what happens to them in the graphics engine rather than an abstracted version in the physics engine.

Generally speaking I have found that physics complaints about Shift seem to revolve around the person either not being familiar with the physical property being modelled, or that they expect the game to automatically assist them (especially on a pad) to the extent that several other driving games do. ed- which is to say, a lot of games apparently don't model wheel hopping, dog tracking, brake fade, about a half dozen other things which I see a lot of complaints about in Shift

The main thing that they put in to make the game easier is that you have "perfect" tyres that stay perfect throughout the race - no underheat, very little overheat, no ablation onto the track, no blowouts, etc. So you get these really nice predictable and forgiving road tyres that never wear out. A lot of the laps I see people pull are kind of like - yeah you could do that one lap, and then there is nothing left in the tyres or suspension for lap 2. In a way that just makes it a fun game - it's about as exciting as the last lap of qualifying in a sim, but there's none of that strategic layer getting in the way telling you to hold back on the car or that would allow someone who drives well in the limits to beat you by pitting better or something.

Anyhow. No the cars don't turn on themselves.

 

[niky]

It's something that has been discussed in detail here before.

It's not just that.

There is no momentum induced understeer in Shift. Overshoot a corner and you magically have 50% more braking power to slow down to make it. Optimistic corner entries that would have you plowing straight into the weeds in GT or Forza can be countered simply by hitting the brakes and slowing right down. Something that would have you spinning out or understeering even harder in other games.

Come up to a corner and have the wrong line? Drift it. Drift every corner, in fact. Since you get "aggression points" for drifting, they've simplified the drifting mechanic in the regular races to make it much easier to perform a drift, as long as you let the game know that you're planning to do it. And if it knows you're planning to do it, it won't penalize you with momentum lost through the corner... or at least, not as much as it should.

In parts, it feels wonderful... and quite realistic... tire-skip and tire-hop... momentum induced oversteer... power oversteer... but once you pass the threshold of grip, SHIFT becomes ludicrously easy.

In fact... to keep the difficulty on a realistic level, you've got to go full Pro, and drive a classic racing line. If you drive the classic lines... slow-in, fast-out... it's actually trickier than hotdogging it from corner to corner.

But then again... it's more fun to hotdog it from corner to corner... which is where SHIFT feels its flimsiest... so it gets old... really fast.

 

[boxox]

Where are the sections that give you 50% more braking power or let the game know you're going planning to do a drift located? I haven't been able to find them anywhere.

 

[niky]

No sections. It's just the way the car feels going into corners.

Even on pro-mode, with the ABS off, it's remarkably remarkably difficult to get a car to understeer off the track. In more sim-like games... it's remarkably difficult not to.

Of course, more sim-like games don't give you kudos points for bashing into other cars, either...

I find it pretty similar to drive a similar car from say GTL or GPL - most cars have quite low downforce, and tyres that don't mind high slip angles and will drag the car back a bit if they get too busy. Again the main difference in how you drive the (unmodded) game is that you don't have to drive 5 laps first to warm the tyres and worry about wearing or heating them evenly. Many tyres in GTL and the "trackday" tyres in GTR Evo and above are remarkably similar in how they behave in their ideal operating zone. I'd actually say it's easier to drive the road cars (viper, ccx, r8 single class) in Evo than it is to drive them in Shift, as long as you've got the car in shape.

Sorry, I didn't realise you weren't unpacking the game and actually looking at anything in there.

They could have explained this better - I think a lot of people went through the game and thought that points on the right side were the same as points on the left, when the aggression points are kind of like a big turd badge that make the AI bash you a lot more. And then the same people complained about being bashed by the AI...

 

[niky]

Sorry, I didn't realise you weren't unpacking the game and actually looking at anything in there.

I started the game one week after it was released. Turned all the aids off and ran through the tiers.

I loved it the first two days. The immersion. The seeming realism. Then hated it another two... then loved it again when I got to more powerful/tricky cars... then hated it again when I realized I was doing it all wrong... that the game engine actually encourages powersliding rather than penalizing you with a loss of momentum... and that it got easier the harder you push.

Add to that the fact that simply installing a modified suspension or a cage on many cars made them uncontrollably bouncy... no matter how you set up the dampers and springs... and that said bounciness simply got worse the longer you went into a race... I just didn't feel like the challenge was doing anything for me.

Granted, it is challenging, but often for the wrong reasons. Many others here were similarly disappointed. The general consensus being that it felt like there were different physics engines in play based on what you were doing. In some respects, the engine feels incredibly, incredibly good and realistic. Light years beyond GT5P. In others, it feels just like NFS... which is just sad. The developer did a bang-up job of bringing a sim engine to the PS3 console... only to have it ruined by what seems to be conflicting objectives imposed by EA. I don't need another "Pro-Street" (granted, SHIFT is 200% better) that holds my hand and keeps me on the track while I play. I'd rather drive by myself... thanks.

We have a long... long and lengthy discussion about SHIFT's game engine elsewhere in this forum.

SHIFT sits gathering dust in my living room while I consider whether or not to pick up a copy of Supercar Challenge just to have something to do while waiting for GT5. Now that I have a halfway decent computer, I'm actually thinking of getting into something more serious on the PC.

It's even better. They rate "drafting" as an "aggression" move, when it's simply basic racecraft. I suppose if there were a drag racing mode, it would also teach us that downshifting is cheating, and give us major aggression points for doing so.

 

[Nigo]

Shadow Wulf 2k > notice a didn't say oversteer, I said "turn on themselves". That's the way I feel

boxox > I get your point. There are people saying Shift is the best of all. Technically, it might well be, but IMHO, as a sim, Shift fails. Badly. I've driven GPL and GTL quite a lot, and even though they're far from perfect, they don't seem to be on the same dimension to me. I did an experiment : I took the SL65 and drove like a "gentleman driver", so to speak. Felt alright. Then drove like a... Mario kart addict (no offencs), braking too late, drifting (involuntarily) through every corner. Not only it felt wrong and looked wrong, but it was faster

niky > agree. It feels wrong the moment the tires start to loose grip
do you have the link to the discussion you're talking about ?

 

[niky]

Knock yourself out:

The Shift Physics Thread

Note that they have updated the game since then to fix some of the problems (they've lessened the "SHIFT bounce") but most of this still holds true.

There have been a lot of other threads complaining about SHIFT's gameplay, but those simply re-tread old ground.

Well, I've spent the last few months playing with modding the game rather than having it gather dust, and I'm telling you, there's not a lot there that holds your hand, that you can't turn off .. and see that there's not that much hand holding in the first place. Mainly, as I said, it's the tyres, and strategic layer things to do with flags, pit lane and other rules. And not a lot else.

We have a long... long and lengthy discussion about SHIFT's game engine elsewhere in this forum.

Well that's good, but if none of you even had the unpacker, it's kind of a "blind men describing an elephant by feel" discussion. You can't see or really change anything.

[boxox]

The UI only tells you so much, and some of that is sometimes wrong. You can set the wing and splitter, but not find out the drag index of the car. You can reduce the weight, but not find out the starting mass. Or say take the inverted oversteer/understeer indicator pre 1.02 - there are actually still some UI elements that will display the wrong info, reset to the wrong thing, unlock or lock the wrong settings, etc.

talking about it, what do you think of the "real mod" ?

Heart was in the right place, but was really just button mashing. Shift to GTR2 and GTR2 to Shift is not something that produces good results without very careful work. It was not careful work. GTL, GTR2, and GTR Evo are much closer to each other than any are to Shift, and even converting between them needs extensive testing - it's the difference between Historix or Power and Glory and "GTL Mod For Evo V1.0". Some settings they brought over scale to a different order of values or assume another baseline constant setting is set to something else.

It was good to the extent that it showed that if you write "GTR2" on something people will think it is realistic, and if you write "Need for Speed" on something they will think it isn't.

Well, if the problem was a lack of induced understeer and unrealistic response to braking, you'll love being able to drive around most of any track in 6th with the pedal on the floor in realmod.

 

[FoolKiller]

So, if we don't have a way to get into the game's inner files and purely play the game as presented to us by the developers (like say on a console) we can't properly judge how the game plays?

If the physics are fine but the intended UI prevents us from having the knowledge necessary to use those physics properly then the game still has problems. No developer should rely on people being able to unpack the files to get the intended experience. That is just bad design.

 

[Christian_C]

I just find the physics to be like the car was steering from a central axis and that the cars were too forgiving.

As far as I know, the UI is the one part of the game that EA had anything much to do with - done by EA Black Box - while the rest of the game was all SMS/Blimey! with a little hand from DICE. The UI is absolutely wretched and manages to tell you about half as much as GTR2's tuning screen while being twice as fiddly to use and ten times as buggy. It's a real piece of ****. That's why it's a bad idea to use it to make sweeping pronouncements about the physics engine

As far as physics goes - there is a certain placebo effect to things when you can't see what it is you're actually doing or what modifiers or multipliers are actually at work. I assure you that no matter what driving game you think is best, it is going to use something very similar to what you see in Shift (or what you see me post from Shift), maybe as commas seperated values, maybe as a big server side sql database, but still just numbers. Which may or may not relate to the UI or anything else really. Just because you can't pull the contents of GT5P out and play with them doesn't mean it's not there

What's the point of buying a game you have to "fix" to get right, when you could buy the game they based the engine off of and get it "right" the first time? (except for getting the new cars, of course).

And whether or not the game feels different after you've modified the parameters extensively doesn't change the fact that it feels wrong if you can't modify them at all. None of this information helps console owners at all.

Same as when I'm reviewing a car. When I say "this car has a terrible engine, it has flat spots", I don't have to go into it with an OBD reader and put it up on a dynamometer to say: "Hey... it's only bad because they've programmed it for economy here, and the closed-loop, open-loop changeover wasn't programmed properly... if we retune this parameter here, change the E-throttle calibration here... it's perfect!"

Said information won't help the people I'm selling the review to. At all. Now if we were being specific and saying this is SHIFT on the PC... then we could do that.

You should try it on PC actually, other than the renderer and basic frame of the game I don't know how much I even run at stock. Turning back on most of the sim features is about as hard as doing a find/replace.

I'll keep that in mind when I'm out buying titles for my PC. Or I could buy something that I don't have to debug at all.

I bet there are all sorts of things we could make up that Shift would do badly, if it did them. I bet it would use instant to make me a coffee, if it made coffee. That goddamn Shift.

SHIFT makes terrible coffee. Totally.

I didn't go into this game with the mindset: "Hey, this is NFS, it's going to be pure crap." I went in with the mindset: "This is SHIFT, it's going to totally rock!"

I bought this game for the promise of realism due to SMS's work on it... I drove it. I was blown away.

After half-a-day of playing, I wasn't. The nannying was starting to get on my nerves.

Whatever your opinion of it... there is an active element of assists, even in the Professional mode. Yes, other console racers do have an element of assist... to smooth out rough inputs or throttle inputs (here's what GT5P got wrong... not enough assist or "slack" in controller inputs)... and Shift goes one better than them by giving you the ability to adjust controller sensitivity... but being a "simcade" racer, it is designed more to entertain than involve. In other words, oversteer > understeer. And this is what turned me, off, eventually.

If they'd only had one more level of realism above Professional, I would have been hooked. But they don't. And you can't hack a PS3 version. So mine is gathering dust. I'm happy for you PC guys for being able to crack it open and get it working like it should... but again: why should you have to?

I think SHIFT is a great title. Great for casual gamers... not quite there for hardcore gamers, but definitely a good effort. And if EA goes on to making a SHIFT 2.0, I hope they finally fix those flaws.

*and all your files show is the modifiers for upgrades. They show nothing of the actual physics files. I do remember the tire grip file being posted before, though... and that one does have some bearing on this discussion.

The same file gets used in all versions as far as I know. I'm just letting you know,

the fact that simply installing a modified suspension or a cage on many cars made them uncontrollably bouncy

is a perfectly reasonable thing to assume when you look at the UI. But when it's actually increasing the multiplier rate for springs/dampers and dropping the cars ride height, basically making it stiffer over shorter travel. So that's why some cars go over a bump and freak out when you upgrade their suspension all the way. If you had damage turned on, you would probably have thrashed it to death doing that. So really the bouncing is the least of your worries there.

What's the point of buying a game you have to "fix" to get right, when you could buy the game they based the engine off of and get it "right" the first time? (except for getting the new cars, of course).

It's pretty common in the sim community - people assume that whatever game they played a few years ago that said it was realistic is the absolute be-all-end-all of realism and cannot be improved upon. The most notable case of which in recent memory was GTR > GTR2, where a few contact patch bugs were resolved in 2, making the cars a bit less likely to suddenly spin out as if they'd just hit a patch of oil (simulated contact patch got reduced to like 1cm x 1cm at certain load levels as I remember). Eventually everyone who thought that way died of acute embarrassment or something and now GTR2 is the gold standard of realism and Shift is the bad guy.

Only. The big thing you notice when you dig into GTR2 vs Shift is that GTR2 uses a one-size-suits-all-circumstances tyre radius/radius at rpm scale/latlong grip level and width, selecting from some fixed curves to suit different circumstances of cornering, acceleration and braking. Whereas Shift calculates it all on the fly based on the stresses on each tyre.

I'm just saying. Realism isn't the same thing as complexity, or accuracy, or difficulty, they're all independent of each other. Shift simulates a less realistic tyre more accurately, and GTR2 simulates a more realistic tyre less accurately. The skill in driving GTR2 is much more about car management, calibrating how you take the course to save up and prolong the period where it drives more like a Shift car. I think there are a lot of dilettantes out there who took one lap in GTR2 and thought "wow this is really gripless and understeery, that must be what realism is!". Whereas the actual difficulty of driving in it is to make the car as little like that as possible as long as possible.

And whether or not the game feels different after you've modified the parameters extensively doesn't change the fact that it feels wrong if you can't modify them at all. None of this information helps console owners at all.

I think you're reading things into this that weren't actually said - very little of the game I run is stock, which is not to say that it's radically different. It's more things like increasing the heat delta for tyres, a -5% drop in grip level, -50% grip on grass and other offroad surfaces, removing the speed blur so I can play it in cockpit mode with no HUD, doubling the race lengths, taking out the more aggressive AIs, etc.

Same as when I'm reviewing a car. When I say "this car has a terrible engine, it has flat spots", I don't have to go into it with an OBD reader and put it up on a dynamometer to say: "Hey... it's only bad because they've programmed it for economy here, and the closed-loop, open-loop changeover wasn't programmed properly... if we retune this parameter here, change the E-throttle calibration here... it's perfect!"

Said information won't help the people I'm selling the review to. At all. Now if we were being specific and saying this is SHIFT on the PC... then we could do that.

It's not really my concern what it's like on console, any more than what it's like on a gamepad, or an SDTV, or whatever. I run it how I run it. My only interest in the thread is just pointing out how the physics engine actually works and what the source data files say, since that's common across all the platforms.

For instance, if you were developing a game on a budget and you wanted the cars to be pseudo-realistic but not really, and kind of turn on themselves, you could have:

erm... quite a lot more than 3kb, not including stuff that isn't to do with driving.

I'll keep that in mind when I'm out buying titles for my PC. Or I could buy something that I don't have to debug at all.

Cool, all you need to do is find a driving game with no patches and no mod support. This one looks like just the ticket

Whatever your opinion of it... there is an active element of assists, even in the Professional mode. Yes, other console racers do have an element of assist... to smooth out rough inputs or throttle inputs (here's what GT5P got wrong... not enough assist or "slack" in controller inputs)... and Shift goes one better than them by giving you the ability to adjust controller sensitivity... but being a "simcade" racer, it is designed more to entertain than involve. In other words, oversteer > understeer. And this is what turned me, off, eventually.

If they'd only had one more level of realism above Professional, I would have been hooked. But they don't. And you can't hack a PS3 version. So mine is gathering dust. I'm happy for you PC guys for being able to crack it open and get it working like it should... but again: why should you have to?

I think SHIFT is a great title. Great for casual gamers... not quite there for hardcore gamers, but definitely a good effort. And if EA goes on to making a SHIFT 2.0, I hope they finally fix those flaws.

All I can say is that you're comparing it to a "sim" that doesn't actually exist. LFS and I hear iRacing work pretty similarly in terms of inducing understeer and drift/countersteering it out. GPL, GTL work very similarly in terms of making you deliberately slide the back out to go fast. That's not even so much unrealistic, that's just what they model, and they model cars that do that.

I'm sure the "PC sims" are very much better in your head, but look - they are just games. They will always be games. They are all designed for entertainment value and commercial market purposes. They all have certain things they do to smooth out input or make controlling the car easier or whatever - some in the physics, some in input handling, some in terms of plain modelling things that are quite easy to drive in reality to start with.

 

[Nigo]

my english is not very good and I can only assume what you mean, but I think you contradict yourself badly

My only interest in the thread is just pointing out how the physics engine actually works and what the source data files say

= you assume it's technically at the top because of the files (which I don't deny)

They all have certain things they do to smooth out input or make controlling the car easier or whatever - some in the physics, some in input handling, some in terms of plain modelling things that are quite easy to drive in reality to start with

= there always are compromise made to make them appeal to the market they're intended

there you are, you just admitted it's very possible they could have made Shift a lot easier to appeal the the masses, no matter how good the core of the physic engine is (btw, applying faked forces is the easiest thing to do in a physic engine...). So in the end the judgement can only be about the car behaviour, and most of us are far from convinced

 

[niky]

Well... actually... now that you bring up this:

Realism isn't the same thing as complexity, or accuracy, or difficulty, they're all independent of each other. Shift simulates a less realistic tyre more accurately, and GTR2 simulates a more realistic tyre less accurately. The skill in driving GTR2 is much more about car management, calibrating how you take the course to save up and prolong the period where it drives more like a Shift car. I think there are a lot of dilettantes out there who took one lap in GTR2 and thought "wow this is really gripless and understeery, that must be what realism is!". Whereas the actual difficulty of driving in it is to make the car as little like that as possible as long as possible.

I agree: Shift is complex and difficult. Accurate, I cannot say, as I cannot claim to have driven the same cars over the same tracks. But realistic? Realistic in the way it models a car, yes, but not in the way it models the driving experience.

Maybe I am a dilettante. And no, I am not reading into your post as to claiming I am... but I probably am... ...my closest point of comparisons to SHIFT are the Tier One cars, which at least claim to come on something similar to stock tires, and of which I have driven two or three. And while it feels similar, there are points where it doesn't. And that's all there is, to it. I don't believe that cars are naturally gripless and understeery in street trim... that's just how they are when you push them on the race-track. Maybe this is lacking in the game simply because we have a tire model that never gets greasy or hot or whatever, but it just doesn't feel right.

Other games do. GT4, granted, had many physics issues, but the general "feel" was there, and for many of the cars that I have driven there that i have driven on track in real life, the way they handle is the same except for the snap-oversteer physics. GT5P is better. Flawed, but better. And a perfect example of having more realism with less complexity as compared to SHIFT.

In GT4, it doesn't take long to suss out the differences between otherwise identical cars by driving them around a track. It's not just in the level of understeer or oversteer, but in the set of the suspension, how centered the balance feels, etcetera. In GT5P, you don't have as many cars to examine, but it's still there. I particularly like the way they modelled the Mazda6 (which is the latest car I've driven on the track which is modelled in the game), as it acts very similar to its real life counterpart. Incredibly sharp and nimble handling (for its size) at 8/10ths... giving way to ploughing understeer at 10/10ths. And choppy over small bumps due to those big wheels (nice touch).

In SHIFT, the MX-5 is the newest car in the game that I've thrashed. It feels very similar, yes, but the behaviour at the limits is also similar (sans under/oversteer under power, obviously) to other cars of the same Tier. Which is disappointing.

Granted, there are differences when you pass the limits unintentionally, (and I'll admit... SHIFT models snap-over on FWD very, very well... and the tire model is, again, fantastic (I've never said it was anything but)) but when you drive at 11/10ths on purpose, the only adjustments you have to make to your driving style are how soon you get on the power. You can brake ridiculously late, turn in relatively easily, and powerslide in cars that aren't really that easy to powerslide in real life without more aggressive provocation.

I'll take your word for what PC Sims are like. But many other people share my opinion of what the basic SHIFT package is like on the consoles. For us, there is no modification or adjustment, unless it comes from the developer/distributor themselves. So there's no joy, there.

Mind you... I have no way of seeing inside the black box, of knowing what's being done there to simulate driving. But the thing is: If I enter 5 and 5 and 9.7 comes out, I'm not going to be satisfied. Especially if I've been promised a 10.

I don't know what "technically at the top" means but yes, if the producer and physics leads say "it's the GTR2 engine with a new damage and tyre model", and you extract the game data and everything is using the same values in the same format as GTR2 other than the damage and tyre model, and even the file comments are the same between them, yep, I'm pretty sure at this point it's the GTR2 engine with a new damage and tyre model.

With a better tyre and damage model at that.

If you read carefully, you will see that what is actually being said is that there is simply not a "simulator" sold to customers at a video games store for use on their ps3 and toy driving wheel. That's a creation of a marketing department. Sorry! Not even iRacing or LFS- it ultimately involves a lot of guesswork and guys plugging in guesstimates into pretty much the same engines they were using in the early 2000s.

I think the car behaviour in Shift is fine for what it is simulating and how. I don't think they did a great job of telling anyone what that was.

 

[Nigo]

I don't think they did a great job of telling anyone what that was.

really ? you should look at the trailers again (especially the one about drifting... makes me laugh thinking of it), you should look at all the discussions about SMS beeing made of Simbin guys (...), you should read Doug Arnao's interview - oh, you read it already

in the end, people were expecting a GTR-killer you're saying it is, and they got lost in sideway lunacy that doesn't look or feel real at all, so much than even the "masses" is saying Shift is pure arcade - which it's not

Seriously, don't take the PC sim snobs at their word GT isn't quite as far off as they would like to think in some ways. In fact there are some features you see in Test Drive Unlimited and GTA4 that you don't see in some PC sims. It's more a question of focus areas of the sim - they are all small scale enterprises with limited manpower and budget and time. So they do some things better than others. And then nerds argue about it. As far as I am concerned I like to play with things so having games with nice plain text and well commented files is a really killer feature for me, which is why I play a lot of GTR2 and Evo and rFactor and Shift. rFactor does the best multiplayer, GTR2 has the best endurance races, Evo is a nice all-rounder and Shift is by far the best for a quick race that doesn't take 10 minutes to settle the car in.

If you came away from any of the PR expecting "GTR" anything you didn't read it very well. Everything I saw talked up "accessibility" and "drivers experience", they were perfectly clear there would be no pits and nothing to do with needing to pit in, no fuel or wear or critical damage. I think there was exactly one instance of them even using the word "simulator" to describe it, and only then for certain aspects of the game. Which is pretty much right.

Drift mode is, again, something they did a great job making and a terrible job explaining.

 

[niky]

True. I remember them pushing SHIFT as "simcade" rather than a true sim.

RE: GTA4... ...you hit the nail on the head. 👍 I don't think I've ever driven a more accurate model of a turbocharged CRX (no LSD = lots of peglegging) or a Crown Vic on shot dampers anywhere.

Despite its incredibly arcadish gameplay, the modelling and car behavior of GTA4 are so organic that you wonder why some of the more "serious" games can't take some cues from Rockstar on how to convey the effects of car behavior to the player.

I bought Shift yesterday. There are some impressive things about it. However, as it's being pushed by many as a simulation, everybody has the right to comment on the shortcomings, or lack of realism, of the physics.

It is very telling when you drive a corner with the external-view, and look at the rotation of the car. When a car is cornering, and loses mechanical grip, it slides. If the rear grip-loss is greater than the front, oversteer occurs. As in real life, this happens in Shift; the rear begins to step out. It takes a force/action to neutralise that rotation; i.e. opposite lock & throttle). But the problem is, the car's rotation is counter-acted even without opposite-lock. Typically, (in the case of most cars in Shift) if you enter a corner with a bit too much speed, the car always very quickly rotates by the same amount, and then stops rotating! So clearly the physics are tweaked to help the cars into power sliding.

It's not the same as GPL (I presume everyone is talking about the legendary, 'Grand Prix Legends'). In GPL, if you get into a slide and don't correct it, you're into the wall (or bush, commonly).

The second thing is the grip. It's like the physics have a sky-high friction co-efficient; the reason you can outbrake yourself and still make the corner so easily is because as you turn in with a lot of lock to try and make the corner, the car slides and speed is scrubbed off rapidly, much more so that real life.

There's nothing wrong with the cars; I'm sure the suspension modeling and things are very impressive. The problem is how the car interacts with its world, i.e. the physics.

Oh and just to add a comment about the actual topic title - "Do the cars turn around themselves?" - No, they don't turn themselves. I'd feel it's accurate to say that the cars are encouraged very easily into a rotation, and the rotation is neutralised typically at the same angle.
