Gran Turismo 7 Physics

[JDMKING13]

Another video of me driving, the car is bone stock, I only have ABS on weak no other assist… No spinning from slow turns… No spinning from braking… (even broke extremely late on lap 3) anytime the car got loose extremely easily to catch… I’ve driven the car 4 times and yes it could get a little twitchy is a GT3 with no assist on what do you expect? Anytime it got out of line it was my own fault… again people where saying the Porsches are hard to drive… in stock form I don’t know what’s better than these Porsches… the turn in is so simple and smooth… you can feel how there is just no weight in front and how it makes the front turn in so well.

We are all trying to get use to a 2 week old game in which even I was caught off guard with the physics.. are they perfect nope don’t know which game is but the way some are acting as in if you can’t even turn the car at low speed without spinning sorry can’t agree with that… the last turn I was feeling my self, the car felt great on that third lap… but reminded me to calm down. 😂

 

[jwaaa17]

i don't have any problem with the new physics model, i just don't happen to be very good at driving it.

 

[sumbrownkid]

Good lord 81 pages and it’s been what, 10 days? 🙃

 

[Veinz]

I took a few days off since the last patch and it feels a little more grippy. I like the physics, they could always be improved but that is a never ending battle.

 

[MadmuppGT]

In GTS it’s the same way man…. Anytime you just move the steering wheel slightly the ASM comes on in GTS… did you not play GTS?? And again the RWD cars are easy to drive sorry that your having trouble…

No this isn't the same. It's on all the time even when not turning the wheel.

Like i said its on all the time with zero input, you turn it off and the car is fighting to spin. Of course once you turn the wheel to enter a curve it spins.
The game is fighting with itself it seems to keep the cars straight whether I'm doing things or not.

Just wondering if anyone is having this weird extreme issue.

Yeah I can vouch for that too. The underlying issues are still present, but it’s much more tolerable now imo.

I will up load a video for you to show you then… and also GT7 the road actually matters… in GTS Bumps and elevation changes barley did anything to you.

In GTS you could go in a straight line once you slightly turned the wheel ASM came one.. give me a second

 

[extreme car]

I just loaded up AC and you cant do this in AC with the GT86. Too much understeer with the eco tires. The way GT approaches the car is more natural. He's not using hand brakes. The slide is being delivered straight from the power of the car. AC the car doesn't turn when you mash the throttle in AC.


Which is? I'm sharing my experience. I drive a EvoX irl. I've had a lot of time in the car. I know how the feedback in the game is. I trained on a track in the game and translated it real world with the same suspension setup (stock) and similar tires. I don't know what other experience can outweigh that.

I know this. That was my whole point in the reply. He wasn't transmitting torque, but he broke traction and snapped right. People were complaining about that in GT Sport. This demonstrates it actually happens. Try this is AC, it doesn't work at all. GT has had the better physics models for production cars. A lot of aspects feel similar between the cars, but there are things GT does better.

here's a tutorial on how to drift a stock GT86 in Assetto Corsa, no hand brake all using momentum.



I find it kind of funny you keep mentioning you can't do this and can't do that on other sims, and I still haven't seen a single clip of you drift a production car in GT7. just because you can't doesn't mean the car won't.

 

[graesand]

@Scaff thanks for clearing up my really **** calculation. It was 5AM and i was wined and dined. I should delete my post but ill let it stand as a proof that im faulty. Most people in this thread cant recognize that trait about their opinions....

This game is so broken, my ps4 is on fire running it and ive had 4 system crashes in 30 mins of gameplay today.... Its just what i expected when i bought it hahahha.

This is GTS you can see just a slight touch of the steering wheel it comes on.. I’m not going fast, I am not swaying the car hard. I’m going very slow and it still comes on… If your on a controller it’s even worst… So no the game is not fighting itself it’s been like that since GTS… now in GT7 the road actually matters a lot more and if it was that sensitive in GTS I can imagine it going off more in GT7.

Here's a different thought, exploring the physics and input with a slightly different tool.

I would urge anyone to take a stock BRZ, Eunos Roadster, 370Z etc. And use the steering angle adapter tuning add-on, as a little experiment.

I'm not an armchair expert and absolutely have no interest in drifting that its intended for, but taking an otherwise stock BRZ and going for some hooning style driving felt very satisfying. Didn't experience any mystery spins in my limited 40 mile test and felt more comfortable over the limit.

I would speculate the underlying change is to the steering ratio rather/or in addition to any changes in the maximum steering angle. This would be easily verified so will spend a little time later on it.

What about very low speed corners?

I have not done any tuning at all yet, but what gave me trouble in the beginning was adjusting to the steering inputs and throttle.. I was either over turning the or giving it my car GTS throttle inputs. Also add in how the track elevation can mess you up now… I can see why I was having trouble.. just didn’t expect GT7 to drive like this. It probably the best part of the game for me, taking all the cars and using them in the different events no matter what I place.

 

[rtsbasic]

There's no problem there. Think more of the feeling if you reduced your wheels effective range from 900/1080 degrees down to 540 degrees. That would achieve a similar output without the added steering angle.

I think a recurring message in your posts is the journey of learning the limits and staying the right side of them, which is absolutely right 100%. My interest in this thread is more for the behaviour over the limit, as everything up to the limit feels fine. Personally haven't put much time into GTS for several months and most of my recent sim time is in AMS2, iRacing & Raceroom. There's not a huge adjustment to switch between each of them, and the adjustment swapping into GT7 is far less than GTS was. If only there was adjustable FOV and a bigger range of driving position adjustment, it would be even more seamless to jump into.

I agree with everything you said, but I’m still confused not so much on what your saying, but members saying and mocking you can’t take turns at low speed.. you can’t brake, you can’t drive the cars, the physics are broken etc… I just don’t get it are we playing the same game? This is not towards you in anyway, I thought the point was to get as closest to the limit, learn each cars weakness and strength and improve your driving skills?

This over the limit talk still has me confused what’s so fascinating? The 911 got slippery on me a couple time… had me nervous to brake also until the third lap. The last sweeper had me literally clinch my whole body up… I’m telling you if I pushed the car any further on that last turn it would have been over for me 😂 how would i save the car if i started to spin? At that speed there’s no way in my opinion.

I am not coming at you in any way I’m just still confused, you have some saying over the limit is totally unrealistic… and you have others saying you can’t basically drive the cars…

 

[Tenacious D]

I just don't know what to say anymore. Or, well, yes I do. It seems that too many people don't want to adjust to these physics, or have the attitude that "assists are for wussies." Or they do but want to complain about them. The second bunch I'm cool with, but the first... why not play something else if everything is "I just can't"? Undoubtedly physics patches are coming, hopefully very good ones, or the whiners are going to get the game nerfed. It would help right now if tire squeal more closely matched tire grip, and complained more loudly the closer we pushed to that elusive grip loss. Not many of us can afford a US$700-plus Fanatec wheel, and we don't have any cues left to communicate with us.

I should take out that 997 for a spin again, stock, and see if I can handle that little freak of nature. Probably not, but I might learn a little more. Great driving by @JDMKING13.

 

[B80]

Last night I played the 3 US car menus (mustang, chevrolet and trial mountain).

Was expecting the chev 'supercar' to be horrendous going by comments on here. just abs full, but was fine tbh.did upgrade to sport softs.
Had to be careful of course, but didn't think it was that bad at all. Same with new mustang.

I didn't play gts, so maybe no 'detraini g' needed? I did play fh5 for 2 or 3 months.

I'm on ps5 controller, cockpit view..

Will try m4 again as that felt tricky, but that was pre patch and i was learning the game.I have m3 f80 irl , and there's no way I'd be wanting to disable stability and TCS on that, particularly if 'racing'. Back sometimes snaps out on straight line when pushing pedal down hard (but not flooring it) at 50 mph in 3rd gear, bone dry conditions with newish Michelin pilot sport 4s all around

Taking a car over the limit while maintaining control is fantastic fun.

I'm not playing it till the physics patches start coming in and don't really mind the wait. It's better than attacking the leader boards now only to see the them reset after each change. I think they did it 3 times with GTS...

...on the whining, is that the new name for constructive criticism?

Kinda related...In GT Sport I've heard some conspiracy but one that stands out.. This one guy was telling me that in the Drift tab, the cars behave more realistically than the Road tab. He basically said all the assists were off and you were getting the raw simulation with Drift tab. I don't believe it but that's what he said. lol

The fascinating part is holding the limit, having the knowledge of how to push it and having the confidence to step past it when you choose How else do we define the limit? Outside of skid pans, the limit is wherever we define it. Each time its pushed you learn a little more. I think we agree there but see through a different lens.

I don't want to post anything that will flame more fires or feed the trolls. My opinion is simply that everything up to the limit is the best GT has ever been. I'm not yet convinced on behaviour at and just over the limit, there's still a lot more experimenting to do. I haven't noticed any specific issues with low speed, brakes with or without ABS. Note that I said the best GT has ever been, not the best driving has ever been simulated. That's another can of worms that doesn't belong in this thread

What I am certain of is the FFB is totally sub-par for the physics dynamics present. Its the best GT has ever been, but its not yet enough. The issues here are well known so until there's change we won't gain anything debating it.

If you want a stick to measure against, get yourself Raceroom set up and test drive the Audi 90 GTO or the DTM 2021 Ferrari at the hillclimb. This experience can be done completely free if you have any reasonable PC from the last 10 years. The FFB is simple to set-up, completely physics based and one of the industry leaders IMO.

 

[nfsp2kTW]

my personal feeling
The Road/Drift TAB in GTS are physically different and far from each other.
GT Sport Drift by Road TAB

GT Sport Drift by Drift TAB


The physics of Steering Angle Adapter - ON/OFF in GT7 is slightly different.
GT7 (Steering Angle Adapter - OFF)

GT7 (Steering Angle Adapter - ON)

I’m sorry my friend I have no computer… I was thinking about getting one though! Also comparing GT games to these all out hardcore racing game on PC would you call that fair? A game where my kids play vs some of the best sim racer/ hardcore racers resides? I mean I played ACC on PS5 and AC… and they are nothing like their computer counterpart.. I got those games because I thought you could do what you see on the computer version buts it’s not even close… wouldn’t you say PC sims racing games are just better than console Racing games overall?

 

[Td04]

Ac on console is good, but really overrated too

 

[wheelhp]

AC on console is limited fun. AC on PC with physics mods, game mods, new features, league racing etc is almost a 9/10 game. The UI on both is bad but customizable on PC with modding

 

[Niop]

or have the attitude that "assists are for wussies."

It's not that at all. It's people that don't need the assists in real life wondering why they should need them in this game.

I'm on ps5 controller, cockpit view..

It should be noted again, if you're playing on a controller, you're playing a different game entirely.


I will say I LOVE GT7's physics up to the limit. Once pushed beyond, they seem a bit ridiculous to bring the car back in control.
I think they need to be adjusted a bit. I just hope they use a scalpel rather than a sledgehammer.

 

[lbpomg95]

So I just had an interesting experience. I've got the VW 1200 (original beetle), tuned up to 60bhp and fitted sports soft tyres. I took it to Tsukuba. I'm on PS4 with a DS4 controller, and when you slow down for a corner, the steering wheel won't turn more than a couple of degrees. You quite literally go straight on, into the wall, and then the steering wheel suddenly turns how you requested. I think this is a more exaggerated version of what I had with the Camaro Z/28 which I moaned about a few pages back. Can anyone else playing on controller see if they get the same issue?

Basically what's happening is certain cars literally aren't giving the same output as my input. So, not a physics problem, but perhaps this glitch might have something to do with why people playing on controller are struggling so much to catch powerslides; they literally can't countersteer enough because of a bug with the steering inputs?

Food for thought anyway...

EDIT: So it may just be that I lowered the Beetle too much at the front and the wheels didn't turn inside the arches. I didn't realise this game actually modelled that. Woops.

 

[Firestone]

This is actually a skill issue, I just tried it in AC and it's quite easy to recreate what happens in that video, it actually feels like a real car unlike GT, also he does use the handbrake just not to start the first slide.

I’m playing on PS4. I saw someone mention a physics mod, so I’m assuming a lot has been changed with the PC version. But I can tell you for certain that the cars don’t turn in or rotate when I’m playing. There seems to be an issue with AWD vehicles acting like open diffs also. The GTR understeers like mad. I can say for a fact in cars like the Evo and GTR, there is induced oversteer from the yaw control systems. The cars don’t feel natural.

In the video, he doesn’t shift weight much to trigger the first slide. I’m at work now, I’ll run more tests when I get home.

 

[z06fun]

If you had ever driven a real 911 in the heat of battle I think the general issues with the physics would be more obvious. The 911 is good to test with because it should be the absolute best RWD case for putting power down. For a RWD car, when you have the Cg really close to the rear wheels like a 911 does, you get huge changes in weight on the fronts with the throttle, and therefore huge balance changes. So when you have a 40F/60R weight distribution type RWD like a 911, it will tend to pickup a lot of understeer as you feed in the throttle. So for these cars, in a partial throttle or heavy throttle situation it tends to be very hard to get the rear to break free from turning hard (this is where the whole slow in fast out came from for driving 911's).
In fact, it's not uncommon for a 911 to lift an inside front tire off the ground under hard throttle. As you can guess the car will just want to go straight when a front tire is off the ground or almost off the ground, steering gets very numb, doesn't matter too much what you do with the steering wheel, the car just wants to go straight in that situation. So when there is very little weight on the fronts like that, it's hard to break the rear free when turning hard as the fronts are not providing much lateral force, which means the rears don't HAVE TO provide much lateral force, so they have a lot of force available for acceleration.

Having driven a whole lot of RWD production cars in the heat of battle over the last 20+ years, the RWD road cars in GT7 so far feel like there is not much change in balance with throttle (similar to previous GT's back to Gt5 prologue at least). So that tends to lead to easily reaching the traction limits and breaking the rears free easily under throttle.
Some specific examples from GT7 that you may have tried in the license testing at this point: the 370z, Toyota 86, and the Alpha 4c should all be quite easy to drive in 4th gear on the stock tires in the dry. They all should have a very hard time breaking the rear free in 4th gear while turning, but that is not the case in GT7.

With that said, most everything else about the physics and driving feels very good/correct to me, compared to previous GT's. Small disclaimer, so far in GT7 I have mostly been using the road cars, I have not tried many Gr.3 or Gr.4 cars.

Completely agree
