You don't like ACC physics?
Oh I do, but GT is different game for a different audience. I play ACC (or use to, i need a new PC) for when I want some serious challenge in the physics department. I play GT (currently) because I like the aesthetic, its casual, tuning opens a lot of creativity within the limits they have, and most importantly I like playing Gran Turismo with a controller.

Sure, and physics for few types of car is not that hard. GT has so many types of everything. Good thing is GT7 doesn't look casual at all on a gamepad which is great.
 
The physics are improved but it needs better ffb. On G29 i can't feel tyre slip or kerbs. I know its GT and not Assetto Corsa but they can at least add some tyre slip effect..
I wouldn't expect them to implement better FFB for the G29 or older wheels. How every modern sim treats "not the newest" wheels is neglectfully, they just implement enough to say it has FFB support for said wheel. lol
 
Why isn’t there literally anyone talking about 0-100 km/h (0-60 mph) times comparisons? No matter the car, it’s just impossible to get a comparable real life time and yet, no one seems to care?!
Someone mentioned that you can't achieve real life times because: you can't adjust tyre pressure for the perfect launch, and you can't shift faster than the game lets you. Not to mention the other variables. But even if all those things were corrected you still wouldn't get IRL times because of the way PD simulates cars.
 
Why is the 98 Integra Type R absolutely demolishing supercars around the track?

Honestly seems like a lot of the JDM vehicles are as good or faster than supercars around the track.
It just feels as if cars from the 80's are insane. Modified, I've had fun exhibition races with others and the C4 can stomp on the throat of some of the super cars. I took a dude with a modified Ford GT for a spin when my C4 comes out of nowhere and just corners away from him. This is even without the Gigantic wing just that cool looking one.
 
In terms of the physics, my only continued complaint is the lack of feedback for rear tyre scrub.
Yea, I hear you...give us an intelligent solution here PD...supporting all input devices.

Edit -- but there is this little thing called driver inputs...which the majority seem to think makes no difference...

The two cars are not exactly the same between AC and GT7, the one in AC is a '14 and the one in GT7 is a '17, the '14 has a stiffer suspension set-up than the '17 (which in turn has a stiffer set-up than the '20).

I've just taken one for a drive around Brands in AC, and the only way to get 'mad understeer' was to go into corners far too hot (which is easy to do, as it's stupidly quick for a road car), getting the rear active on 2 gear corners wasn't an issue either, and certainly not like an open diff, which would have seen power spinning away, and I found it flows perfectly well, in fact for a car of it's weight it's stupidly agile.

Edited to Add:


Stock car and track, no mods for either. TCS is either off or at its lowest setting, ABS, but no Stability Control. I even left the tyre pressures stock.

I haven’t driven a GTR, so I can’t speak for it, but I know it and the Evo share similar concepts, but one thing I noticed is the response of the steering. When you get on the brakes and start to turn in, the car understeers and refuses to respond to input until you get to a certain speed then it snaps in. I guess that is my problem. In GT the Evo and GTR response to steering feels similar in that they are very responsive to input

Just drove for 20 mins around Laguna Seca. I can't get my head around it. It's easy to drive, but turn in feels stiff and unresponsive. I enter the corner straight, turn and power out and it will oversteer when you apply the power, but braking and turn in seems very lazy and throws in an understeer condition before it decides it wants to rotate. Lift off conditions are a bit lazy also. Same with low speed corners. I would assume the GTR has a better AWD system than the Evo as the Evo's system for the Evo X is from 2007. When I trail brake in the Evo, it will yaw the car with the front brakes sending more pressure to one rotor than the other to help turn in. If I'm off throttle and turning, the clutch packs in the rear diff will deliver torque to the outside wheel of the direction I'm turning to further rotate . The steering ratio also allow the car to turn in rather quickly, so initial turn in is rather snappy. It's a chunky car also and not too much lighter than the GTR. Wish they had the Evo in AC so that I can have a better comparison.

It Is the same for all cars on Ac: they Just understeer a lot and weight transfer are really cheap. For me the game feel really disconeccted, even if It has a cool ffb.
My feelings Is that You are not turning the front of the car, but the car turn on a axes from its center (its visible with external Camera and on replays).
The more i play the more i keep think It has a really overrated physics, even with its cool stuff like tire pressure, Better aids...
FF cars are well done.

Is this another issue like you had with the GT86 that doesn't actually exist and/or is just user error?

Those times vary so much in the real world as is. Tyre, tyre pressure, tyre condition, track surface, track temparature, ambient temparature, altitude, fuel.

Depending on which Evo X you're referring to the GTR is up to 300kg heavier, which is significant, and will certainly blunt performance in comparison. Yes it will understeer initially, you can see that on my video (and as almost every road car on the planet is specifically built to do so), I'm using a slight amount of left-foot braking to rebalance the car (again visible in the video), which negates the understeer and makes the car quite manageable.

I've only driven an R35 for about 20 minutes on the road, and it was a standard model, not a Nismo, so I'm not stating it's 100% accurate, but I'm not finding it as you described it. However, for my money, having experienced both systems, and despite having worked for Nissan, I would rate the Mitsubishi system, over Nissan's. The Evo X is also, has a lower weight, shorter wheelbase, and narrower track, going to have a lower PMI. It's naturally inclined to want to rotate more. Keep in mind that every review and track drive of the R35 states it's stunningly fast and dynamic, for a car of its size and weight. It's a big and heavy car, and for that what it does is remarkable, but it's still going to be a factor.

A car, In AC, on PS4, not rotating around a fixed central point (now cars do rotate around a central point - it's called the yaw point, but it's not static, in reality, or AC). The correction of the oversteer for the AE86, can be quite clearly seen (in nice slo-mo as well) to be at the front of the car, as the rear comes back in line with the yaw point around the centre of mass. You can also see this for the E30, from 7:07, and again at 7:57, in the same video, and again in the video I posted yesterday from 0:07.

Good that you have outlined the differences here so aptly. Godd Job!

You @Firestone can't compare the Evo X to the GTR and to simply say the GTR's 4x4 is better than the EVO because the Evo is older is a bit naïve.
The Evo is known for having an extremely good and very dynamic powertrain, plus all the other advantages of the Evo over the GTR.

Don't get me wrong, I love the GTR, to me it's just a "living" legend and it's really impressive. I haven't been able to drive a GTR myself yet, but I've been a passenger for a few "entertaining" km and I know that it can be a real beast.

This is probably the single most evident bit of evidence that there is something flawed in the rear tire physics. Take any car, rev it to redline, and let it go....engine pings off the rev limiter with zero initial Traction or forward progress. It isn't until you let off or shift that the car starts to proceed forward.

I personally have come to enjoy the challenge of the physics, but do still agree that they need to incorporate some sense of friction occurring when the rear tires begin to break Traction. Atm, it's as if the hit ice whenever traction is broken. Otherwise, I'm enjoying the overall feel of the cars driven.

Not to mention the other variables. But even if all those things were corrected you still wouldn't get IRL times because of the way PD simulates cars.
What kind of argument is this? This way you could make 100 other reasons why... Yes, GT7 lacks tyre pressure adjustments, but how exactly does it prevent people from attempting to recreate 0-100 km/h? These times should still be reasonably close if done right.

That may be because we don't have launch control and proper TC in GT7
So? Most cars made earlier than 2010 don't have launch control, and most 90s cars and older don't have TC. And let me tell you, GT7 has much better TC than many real cars I've driven. For example the base C5 Corvette has terrible and incredibly snappy TC. So bad it made me almost crash the car a few times. So really it should achieve 0-100 km/h faster in GT7 (once it arrives) compared to real life.

I don't want to imply anything, it may be that you are sooo much better than me, then you have my highest respect.

I give you 2 very easily achievable tasks.
2 vehicles:

Chaparral 2J
and
BMW 3.0 CSL

both fully tuned please.
The tires are completely your choice.
Both vehicles without tools without assistants as you say you can do it.
On the Nürburgring Nordschleife or 24h track... and I would like to see a video of each of you, please.
With the Chaparral 2J you must not need more than 6 minutes, a time that is "easily" to achieve.
The BMW must not need more than 8 minutes, each time on the Nordschleife.. on the 24-hour track 1.5 minutes more each time.

Pretty fun to watch how this guy struggles to keep his X-BOW on the track. I recommend watching especially from 9:55 for the X-BOW footage, and his summary from 16:18. He also mentions some other folks who are into racing that have issues with GT7’s lack of oversteer grip.

I also usually drive with TCS on because GT7 just feels a bit more realistic that way.

And running TCS is basically a must in a long race. I’ve never seen so many people spinning out in GTS’s top lobbies as I’m seeing in GT7. And looking the replay, it’s those people who drive without TCS.

Exactly, he says what is rather clear. So I was surprised if no aids is about getting good. :D I don't know what kind of good it is because you can't feel whole car in GT7. It's very cool to play but that's it.
 
I had a ND MX5 2 liter for a short time this winter and had quite a lot of fun exploring the limits of grip with it. The thing I will say is that physics model in GT7 needs some revisions because it's easier to drift the 1.5 liter MX5 in GT7, than it is to drift a 2 liter ND MX5 in the middle of a Detroit winter. I also get a lot of squirrely suspension dive when I trail brake without activating ABS in almost all cars in GT7. I've never ever had this experience in real like where trail braking can actually cause lift off oversteer. Oh and the license test with the RCF is just broken. The RCF in real life can't spin 3rd gear at all with half throttle on corner exit, while in GT7 it sends all of the power to the outside wheel, and trying to straighten out makes it spends 3 seconds trying to distribute the power through the diff. Yeah sure I know that we all have to adapt to a games physics model, but the physics model in GT7 is a few levels behind Project Cars 2/Automobilista/R3/iRacing.
 
I use TCS1, no way would I dare go aidless in Sport mode, not worth the risk. Bear in mind these fast YT drivers also all have DD wheels which are apparently much easier to use in terms of recovering from loss of grip due to their near instant response curves. And they play any hours a day.

But yeah, this game is kinda wack. In race cars the physics are acceptable in that you can still drive and have fun. But in some of the road cars its odd. Have you guys tried Mission 1 on Rolling Stone (the pass)? Your in a Merc SLK on SH tyres and have to overtake on the green hell, my god, it's like being on ice. I just can't believe that car, even on hard sports would be like that. It's nuts. I had to put TCS on 3 to make it driveable.

The cars are not hard to drive, however some cars just need to be respected more than others. These are typically your old cars, super cars, high powered, cars race cars etc… I can take take a 370z and turn off all aids except abs weak.. and be comfortable in a 10 lap race.. If I was in my F8 that would be a different story. While I could easily drive with TCS off and ASM off during a 10 lap race could be extremely stressful.

I drive the cars In GT7 just as they would be represented in RL… it’s one of my favorite things about GT because you have the options to fine tune the car… For example I’m in love with the 308 GTB I run it with NO TCS NO ABS NO ASM I downgraded the tires to Comfort Hards vs CM and the car is so fun to drive. It’s no where near ready for real track days but for the lower events I can take top three easy. 😂

@Animera There is definitely a difference between ABS default and ABS weak
 
I've just spent far too long clearing up this thread, resulting in over 40 posts needing to be deleted, simply because a few members were unable to carry out a conversation without resorting to personal attacks, petty digs, and caps-lock shouting.

Unfortunately, this has also resulted in some posts getting caught up and also being deleted, as I do not have the time to go and edit close to 30 posts to keep what's OK and removed what's not. To those members caught in this mess I apologize on behalf of the members who seem to think the AUP is optional.

To those that started this mess, I want to be 100% clear. The AUP is not optional and you agreed to follow it when you joined, you also agreed that you understood that failure to do can result in action being taken, up to and including losing your access to GT Planet. Should I see any repeat of this kind of behavior, you will find that moderation action will be taken and you will not be given the courtesy of a heads-up in the future.

This is not open for debate or discussion, it's an instruction. Fail to understand that and your posting rights in this thread will be removed.
