Gran Turismo 7 Physics

[FA_Hayes]

This is so on point.

Its just sad that ppl who play nothing but this game still think its real, good and defend it. Its like theres a lack of reference. Oh well hello pc sims. Hello real car.

I had high hope for GT7 but feel underwhelmed to be honest. Everytime I play I keep sayingi do I can't wait to upgrade to a PC setup soon because it's not scratching the itch and I can't break real life habits to go faster in GT.

So I've accepted the game for what it is and just try to have fun before I get more serious.

how is dropping the RPM while still maintaining drifts more realistic? I can and did recreate the hot version video but that doesn't mean GT7 physics is realistic, I had to do a lot more corrective steering and throttle just to copy his drifts.

btw is this a different replay from the first one? this drifts look smoother than the previous replay. if it's congrats you're getting better at it.

It's a different replay. Thanks for the complement. Regarding the drop in rpm, what I was saying is that when I did that, it was ruining my drift. But I was jabbing the throttle as in the Hot video to keep control of the steering angle while maintaining high RPM to keep the tires sliding.

In this case what I mentioned isn't happening but it is something that happens in GT.

I haven't really noticed that in GT. Exiting drifts at high speed, rear tires can still experience traverse motion. You can still feel the resistance in the feedback. I used to mess around in my Evo all wheel power sliding with crappy eco tires and it's a familiar feeling.

the Subaru STI on the other hand, while still a confident car, can somehow still POWER OVERSTEER with 50:50 power distribution coming out of a third gear corner with 360hp on SH tires. AND THEN when straight, power on, the fronts should be pulling you straight, but it will sometimes STILL snap over if it isn't 100% planted. This is not how AWD cars work. Period. This simply doesn't happen IRL,

I'd like to note that it is possible to get a AWD car to oversteer on power with 50/50 power distribution with a stiffer rear sway bar. The STI's case, not quite sure what to say. It understeers mad, but you have to be fully balanced exiting a corner on heavy throttle to cause the oversteer. There are some vids on youtube of it power oversteering out of corners, but it's not a condition you want to be in with the car.

GT7 physics are designed around the controller first and steering wheel second and most of their users are on controller, it seems in GT7 they have gone even harder on this because the FFB, canned effects and wheel behaviour in general is just bad for 2022. The cars are behaving bizarrely in GT7, especially on street tyres. The race dry tyres aren't as bad (in dry conditions) but the sports and comfort tyres are just really rubbish in terms of realism.
They need to just take "the real driving simulator" off their logo and then we would be cool, calling this a Sim in 2022 is like calling GTA5 a city driving simulation. Yeah... But nah..

GT7’s physics are fine and majority can be translated to real life. It does better than some highly regarded sims around here. Too many people being dramatic around here. Lol

Nobody notice how TCS1 is less intrusive? That’s the first thing I notice driving my F8 this morning. In stock form with downgrade tires (Sport hards) and TCS1 this car is amazing. I was stuck with turning it on and off because TCS off and this car is just ready to smack you with bad throttle input… with the TCS1 you can be more aggressive on the throttle and not have to worry about being in a wall Lol. Just love driving in this game!

No, no they are not, and no it will not translate to real life. And NO, even sims from the early 2000's have better physics. Im looking at you; richard burns rally and you, LFS.

Take any old pc and your wheel, try it for yourself. Spend a small amount and buy a cheap rwd car with crap tires. Do anything else to compare GT7 and then maybe you get it.

The only drama seems to be people who are so oblivious of other perspectives that they will defend the physics engine in GT with really thin proof and arguments.

This thread is such a meme. Incredible.

I really hope this is true.
I may actually be inclined to use it now.
I'll give it a try later tonight.

What kills the F8 with TC in general is that it kills the turbo spool when it kicks in. It not as bad as it was before the update though, and if I put better tires on it would combat the TCS also let me know how it goes!

I agree 100 percent.

The WRX sti that's in the used car lot understeers exactly like I remembered the real thing doing.

The Evo X claws itself around corners with its active yaw control. Needs suspension tuning like the real thing does.

BMW M4 could use a bit more grip but turn in and stability through corners is on point. It feels planted like the real thing but easy to get the back end in a control drift just like a M car should. Torque curve with minimal turbo lag is damn accurate.

BMW M3 E92 and civic type R Fk8 also extremely accurate.

I need to test more cars with the wheel.

So simulate physics is just about snap oversteer? It seems you are the biased one.

And lap times with stock cars and tires are accurate too. On Ac you need semislicks to get accurate lap times,but Hey lap times doesn't mean nothing.

Didnt even mention snap oversteer???

Its a very basic arcade game, nothing more.
And its doing a piss poor job at simulating anything.

It’s simulating your anger pretty good. 👌

I've found that after I started using the extensions every controller after that felt weird, but I don't play a lot of games and the ones I do are usually car based.

You might be onto something with it changing the caster, much like one would add to a drift car to facilitate the steering having an easier time honing in on opposite lock, but I'm not exactly sure. All I know is that with the angle kit the cars seem more forgiving past traction. It doesn't even really feel like the FFB is more attuned to matching slip angle, but like the steering allows for more of a "safe zone" where you can modulate throttle and hold that slide. I had some really rewarding moments in the C63S today that were a blast.

I'm not sure what you would like me to test, but I'm game for it! I have an FD IRL so of course it's one of the first builds I did on 7! Its a 610ish PP 390hp widebody with the angle kit, SS tires, LSD, suspension... yadda yadda. It took a long time to get it dialed in in a way that allowed for it to be playful AND not be a snappy killer, and I'm still playing with it, but it's pretty close. If there is something you'd like to see that I can help with I'm willing to give it a shot. Sport hards are fine most of the time, I just prefer the feel of the softs as I think they perform more like a modern ultra-high performance tire should, but it doesn't take but a moment to change things up and see what the results are!

Let me know.

just resurrected my RX-7 FD from the dead and made it into a 600pp SS tyre beast online. Setup was done by my PSN friend, I can now keep up with the AWD big boys like the R32, and R34. It now handles close to a Gr.4 cars but that snap oversteer is still there when you overdrive the car. Unfortunately he told me not to share the tune because he is afraid the awd cars becomes even more OP online with his setup.



clip of me racing against the R32 and just keeping up with the R34. also tried it on the Tokyo 550.000 Cr. race just now and was able to get a comfortable lead with the setup.

Yes, i noticed. TCS 1 is almost like TCS 0 earlier.
TCS 3 is like TCS 1 before, and TCS 2 is kinda fast

Spoken like someone who has no track time. FYI, I have seat time and you are comically wrong.

Wrong in what?

What are you implying? GT7 is a simulator?

Well it simulates driving cars, so yes

The Evo is very accurate and responds on power and weight shift nearly identical to what I experience irl.
I haven’t driven an STI irl, but I do know this current generation has better turn in than the Evo and doesn’t understeer as much on power.

In real life, do tyres turn into ice cubes the moment you step even slightly over the limit?

 

[BigSarj]

Whether it's physics or setups, the R8 in the Deep Forest Circuit Experience is unforgivable.

 

[NikNakTobasco]

Jumping back into circuit experience and is it me or are they stuck with the release game physics? As @BigSarj said above, the R8 is actually funny. Sector 2 in particular is just dumb.

 

[m76]

Is there even any chance the physics and FF will be fixed? Is polyphony even aware that there is an issue?
Should I sell my copy of GT7 now while it's s till relatively fresh, or is there a shred of chance that the game will become something enjoyable?

 

[m76]

Also trying to avoid the limit by shortshifting achieves exactly the opposite in this game, you can't even make this **** up.

I feel like that's just more of a happy coincidence than anything. And I don't mean that to sound disparaging. Game is great, given the wealth of car variety. Not sure it's really a sim though. Single point tyre model, static tyre pressure, no track temp (not even sure it properly models tyre temps, just scripts cold tyres). These are missing basics that sims from the early 2000s had. Not to mention modern sims that go well beyond that with multi-point (or even full contact pad) tyre models, tyre flex and deformation, flatspotting, hell, they even simulate friction heat in the diffs, or the heat from the brakes increasing tyre temps/pressure. It's on another level. GT is a simcade, albeit a very good one.

Lately I have noticed that there are some issues with the FFB. I don't know if my settings could improve that (I maxed torque and left it alone otherwise, feel free to tell me how wrong I am). The snap oversteer is a big issue on its own, but the FFB makes it even more difficult to manage. I pretty much have to use my eyes and ears (tyre squeal) to anticipate slip, because the force feedback isn't giving me enough on its own at times.

The FFB is very weak in this game. You can't really feel the road through the wheel and have to use visual aids. Someone here said they had to crank up their wheelbase to 8nm just to feel the oversteer, so those of us on belt or gear driven wheels have no hope. Even some DD wheels are under 8nm.

Good FFB would make the game a lot more driveable.

I'd add that GT was a very good simcade until now. GT7 is a wannabe sim, that is trash as both.

 

[driftnick13]

Tried drifting in the new patch in few different cars, FFB is still awful with almost no feel, tried to pin point some other issues, using the handbrake and clutch it feels like they have a delay, I find myself turning in and pulling the handbrake expecting the car to react instantly but it doesn't, any time you do a clutch kick or dump it's the same making is nearly impossible to use the clutch like I would in real life.

The issue I was talking about about it feeling like the rear wheels are spinning but the car drives straight I was able to recreate, in second gear with the car bashing off the rev limit it will drive straight from 80-120kph, it's like something changes when you get near the top of the gear, it sounds like you should be getting wheel spin but the car drives normal, it's not what you would expect to happen if the car straightened, either the revs should drop or the car keep sliding but it will sit on the rev limiter and drive straight.

Spoken like someone who has no track time. FYI, I have seat time and you are comically wrong.

LFS is much better then GT7 when it comes to drifting and driving at the limit as someone that has a bunch of track time doing it.

 

[kilesa4568]

How cool. Loads of new events to do with the same daft physics. Looks like I'm pinning my hopes on the next patch then.

Patience is wearing unbelievably thin so I reckon I'll broaden my horizons with an F1 game till then. F1 2021 deluxe edition has got 80% off (£14.99 instead of £74.99) till the 13th so time to finally give F1 a shot.
