Gran Turismo 7 Physics

[Terronium-12]

Holy 🤬 , I think I've found the worst handling car in the entire game: the '07 Ford GT.

A car revered for being a better track torpedo than the Ferrari's of its day handles like absolute dog 🤬 here. At Daytona Int'l Speedway, I purposefully shifted into fourth and exited out of the T1 hairpin and it snapped violently. I tried catching it because the speed wasn't there much at all and it just kept fishtailing left, right, and center.

There's no way you expect me to believe this car has the chassis rigidity of a 1972 F1 car, and even that's an unfair comparison because that'd probably handle like a 50's era car here. There's more cars in this game that are going on the "never drive" list than those that aren't, and it's honestly pathetic.

I'm terrified at the thought of how the Mk. I and IV are going to handle. Terrified.

 

[BlazeTheCat05]

I'll throw my hat in the ring. I strongly dislike the physics of this game at the moment. The snapping out and total lack of rear grip ruin the experience for me, personally. So many cars I was looking forward to, all dashed by their inability to remain planted through a corner even while utilizing proper throttle and steering control.
Now I'm sure I'll be told to "GIT GUD", but since I'm VERY far from the only one who dislikes the physics, am I unjustified in speaking my mind? I'm not an impatient or bad driver by any stretch. This is just...shocking.

I spend 4.6 million credits on the Mark IV race car. It can't drive at speed in a straight line without going for the wall... I used it once.

It's so random. The R92CP and 787B handle great in the license test and mission. Yet the modern 908 will spin around at any opportunity. While the TS050 runs great again.

 

[RaceFace85]

The old muscle cars are funny. Just add a street suspension and it is impossible to drive a branked curve without spinning out.

I'm not surprised one bit. That's one more car I'll avoid then. Such a shame.

I've synced up Hot Version's video to mine, just the 2 corners on the infield and last corner is not really synced but close. gotta give massive points to replay mode in GT7, no racing games has come close to GT7 replay everything looks so nice even on a base PS4. Also I wish I turned off the music on my replay, oh well.

Oh and GT7 steering wheel animation is only locked at around 360 degree, so you wouldn't see my steering wheel see sawing like crazy when applying the throttle on exit cause I have no idea if the rear tyres were going to murder me with the on/off over the limit tyre grip.

I'm running the same setup for PS4. Never thought I'd read this! GIMX has been a bit fiddly with the USB port dicsonnects lately. That's some impressive driving given the physics

 

[zegrated]

Really dislike the physics in the game so far as well. Bought the Porsche 911 GT3 '09 and it was nearly undriveable on the high speed ring on the banked corners with traction control off. Just snap oversteer with no warning while in 4th gear while only giving 10% throttle. Very frustrating, not fun, and I don't believe this is realistic either. Hoping for some patches in the near future...

 

[wheelhp]

Just to make one more point that no one else has yet:

There is absolutely ZERO chance that GT7 can accurately simulate the realistic physics of over 400 cars, some that likely have little to no documentation on how it responded. It's just not possible.

Therefore, they are using a set of rules (or mathematical computations) to decipher handling of cars on a generic way.

This fact alone should be enough to prove that the physics are not realistic. They work for some cars, and don't work for others.

It depends on your definition of accurate, is it 1:1 or is it "good enough to pass as real"?. For me I'd tend to say that I lean towards your argument either way since in my experience with every single GT game (minus GT1/2 which I haven't played extensively), the fastest cars, driven by the fastest drivers in basically all of the time trial records were the ones that were tuned not realistically, but through exploiting the game's physics models. I've also tried some of those tunes and thought that it's very strange the level of grip those "spreadsheet tunes" had compared to everything else. Just screamed inaccuracies with the physics model(s), at least the implementation of said physics in game was questionable when pushed to extremes, which it shouldn't be if it's aiming for any semblance of physics realism. Perhaps GT never aimed for an entirely realistic physics model, but one that was decent enough to have some fun with, which is at least partly true since I've been playing GT games for this long and enjoyed them. We all have enjoyed those older GT titles even with their flaws. That's my point.

Randy Pobst Instagram Post from Driver Training

Thought it was funny he posted this today. An example of how subtle a slide can be and how even a small amount of throttle at the wrong time can initiate a slide.

Not really trying to make a point with this either way. But I'm sure it fuel this fire 🔥 lol

Really wish they had telemetry for replays in GT7

Linking that video comes across as a bit disingenuous given the context of the discussion.
Is that slide with traction control on? I saw a symbol that suggests it could be on

But there's too many variables for this to be taken seriously in this specific discussion...
for example, did his tyre fail?
Was it a cold set of tyres?
Did he repeat this exact accident at this turn?
Was it a hard compound?
What were his tyre pressures? Any modifications done to his car, what was the car?
How many other cars were on the track?
Why is it such a short video with no more information given to answer these questions in the description?

Was the track properly prepared? You can clearly tell that's not the best racing track in the world with all the patches in the road.

There's a lot of variables IRL, but it can be certainly taken the wrong way in this discussion...No disrespect to Randy Pobst but that's too short of a video presents too many questions, not enough answers and certainly supports the wrong kind of discussion with how little we know about that video, because we do know something's indeed up with the physics in GT7 at present, which is an issue for multiple cars, multiple drivetrain layouts, and multiple people, it could be just the tyre physics itself need some updates.

If Randy Pobst thought that video was the perfect video to show here, he'd link it himself. Instead you have linked it, you're not Randy.

Even worse, the main point is not that cars can easily lose traction and start to slide. The actual point people are trying to make is that it's ok to lose traction (over the limit), but that most slides should be recoverable and not snap oversteer to oblivion. That video shows a slide and he promptly recovered without issues. In gt7 you will just keep sliding and spin out most of the time.

The weight of the car over crests and jumps still feels weirder than how easy they are to unsettle to me. Fisherman's Ranch jumps look like a Dukes of Hazard slo-mo when you take it flat and either a nose or tail landing creates a very unnatural bounce to the car. Very odd looking. Not to mention the fast bumpy bit on the 2nd half of the tracks. The nearest I can get to how that feels is a pebble skimming on water...

Just thinking out loud here but if the gravity is weaker, the expected contact patch on the tyre wouldn't have the same grip in a turn would it?

I think the weight generally feels like it’s a seesaw and quite binary rather than being linear in where it is and how is shifts around the chassis.

I think everyone can agree the rally physics are completely broken, I don’t see them building a whole new physics engine just for a couple of stages that hardly anyone will use.
I took this from Reddit. Guy said he’d maxed front downforce but whatever it seems a bit odd.

I totally agree with you. The physics on most RWD cars just ruin the game for me. Everything is great except these terrible physics, I drove the 2020 supra a couple of times irl and the way it handles in game is just ridiculous. That snap oversteer out of nowhere is just so not realistic..

Now that so many people complain about the on/off grip, it might be a good idea to publish a proper gtplanet article about it @Scaff 😄

The more publicity this gets, the better. Hoping and praying for an update soon. Wouldn't even mind if they rolled back to the Sport physics or something (If that's even possible).

"There is absolutely ZERO chance that GT7 can accurately simulate the realistic physics of over 400 cars, some that likely have little to no documentation on how it responded. It's just not possible.."

Most likely. But as a seasoned old tuner I can say that this is not only a car-physics problem, it also comes from the basic game-settings.
Meaning; all cars handling would be improved just by changing this ingame "extras". But since PP fist made it this way I doubt they have eyesight to ever clean it up

Let’s not go crazy here. GT7 physics is a step forward. The suspension physics is awesome… It’s the tyre grip that seems to be an issue.

A major issue. Cars designed to be easy to drive but fun are downright death traps in 7, such as the ND Roadster. Maaaaany hours clocked in with that car on Sport, and maybe 2 minutes with it on 7. On Sports Hards.

Tyregrip is a part of the problem but notice how the cars snaps & spins like they were epileptic..

Odd indeed, cars don't just crash at high speeds or whatever:

True, RWD physics are completely broken, just look at the totally unrealistic behavior of the BMWs throughout this entire video:



Cars shouldn't get loose at 60kmh like that!

 

[unfairlane]

Ever driven a car?

If you drive like an idiot, you're gonna crash no matter the speed bro.

This is one of the most stupid threads I've ever seen on the internet. Doesn't anyone listen?

5/1 in-game FFB, 100% in the wheel, and don't turn past the point where you start sliding, where the FFB becomes smooth/dead. How ****ing hard is it? Stay within the boundaries where the FFB feels lively/bumpy/harsh!

You're all steering too much and then pin the throttle - of course you're spinning out! What did you expect?!

I have zero issues in this game without assists. And I'm far from alone. It's great in every way with every car in all circumstances. Just ****ing listen and try it out before you waste hours here whining and comforting each other like some stupid support group, for a problem that doesn't even exist.

The problem exists, it just does, there is a fundamental issue with grip/slip and tyre modelling as it stands. There are far more people in support of this notion than against it. No amount of swearing is going to change the reality of what is currently somewhat broken physics in certain scenarios.
