Gran Turismo 7 Physics

[HenrySwanson]

I’m very impressed with how the physics are in GT7. I did a test with the AMG GTS. It’s the same car that I race in real life in time attack, and I did every comparable mod in game that I have done to the car in real life. I have to say I was blown away with how spot on the physics were. The car felt just about identical which was very surprising because the car did not feel anywhere close in GTSport. The physics changes in GT7 were definitely for the better atleast in this case. I’ll test out a few other cars that I’ve raced in real life that are in the game and report back but so far I’m very happy with it.

Very interesting to hear that. Did you have traction control on it in gt7 and if so what value?

I had it on one, figured that would be the most comparable to the TC I was running on track in race mode, but I’ll try it out without it too just to see if that makes anything weird happen.

Do any of you guys play AC? Or ACC? I remember reading @Scaff explaining why AC was one of the top dogs in the Sim scene.. I was huge on GT so I had to see for my self… got the game got the DLCs and went to work… drove for like ten minutes and got right off! I was thinking scaff was insane lol! I couldn’t not do consecutive clean lap for a long time! I love the sensation but the cars felt like they had no grip what’s so ever!! I start watching videos and notice I was over driving the car because of the throw the car in the turn nature coast a tad and smack the gas nature of GTS. This was def not the case for AC chassis balance smooth steering inputs/throttle inputs was a must. The game might be outdated but the driving is still good til this day to me. GT7 is giving me these same vibes… still under AC a little bit in some aspects but way better than sport in my opinion.

@fortbo would you ever run your real car with TC off? I know on ACC I can’t turn it off at all and Do fast clean lap.

Yeah I can agree with that completely. I’ve been playing a lot of ACC lately and it’s miles ahead of GTS physics. GT7 still doesn’t feel quite there but it’s very close for sure, a lot closer that GTS.

Edit: just turned off the TC for a few runs on GT7 and everything felt really sorted. It was easy to catch slides and everything felt really controllable. I’ve had the TC fully off a few times on the real car and it felt close.

I've just finished a wet race in heavy rain at Spa and the AI felt pretty overpowered in the wet! The car in front of me (GT3 997) was basically driving like there was a light coating of water on the track while my car (GT3 996) could barely keep in a straight line. It would be nice if they could address the balance of that a little better because right now they feel very very unnatural. Having them make mistakes due to the water would be nice too.

 

[NikNakTobasco]

I did rule out that the rear end bug is related to any weight reduction. I thought maybe for some reason, the weight could've been removed from mostly the back half of the car, but it isn't that I can tell.

Here's some suggestions to help fight against this bug in the meantime. Any combo of these should help keep cars under 400HP (mostly) stable:
- Install a rear wing and increase the rear downforce, remove any front downforce. Remove any front downforce regardless
- Lower the rear ride height to the floor and raise the front height closer to the middle-ish.
- Buy the Fully custom LSD and drop the Initial Torque and Acceleration Sensitivity down to 5
- Increase the front roll bar to about 7 or so and the rear to 2 or 3. You'll know when it's better when you begin to turn in and suddently you feel some resistance when turning into the apex
- Increase the front Natural Frequency and decrese the rear. Try small amounts both ways at first, usually a difference of 10-20 between the front and back
- Remove any front camber, that is only helping the car rotate more, which we don't want atm
- Racing Soft tires if you still need help
- If you are still having trouble and your car is over 400HP, then enable all the assists; TCS at least 1, ASM on, Countersteering Assist Strong

How many credits does all that cost? My conspiracy theory in action right there!

Thank you for sharing your expertises! It’s awesome you do this for a living! I am really enjoying the driving in GT7 I just feel while people were saying it’s close to GTS it’s kinda not in regard I feel on edge when driving these cars on the limit.. I just did the IB-2 with the F430 and yup I spun the first 3 times but finally got gold and it felt great (just abs weak) onThe cars all feel different and it’s cool trying to figure out where the limits are within them! Thanks again for the info..

I dunno who decided to setup the stock settings for the Dodge Hellcat , may I suggest they be bent over and have a rotating pineapple covered in deep heat shoved up where the sun doesn't shine .

No problem! Although I wish I did it for a living, I still get paid but it’s not nearly enough for it to be a living. It’s incredibly hard to actually make a living off of racing, unless you’re a factory driver in a top series. For me it’s just sponsors covering season costs, free and heavily discounted parts, but it still helps.

 

[NikNakTobasco]

I get the satisfaction of spinning out 10 times then nailing it for gold. But when it comes to doing actual races against real people this is where the lack of consistency and confidence is going to really suck the fun out of it.
On another note, seeing streams of the rallying I have a feeling there is something fundamentally wrong with the gravity in this game or something. The jumps are odd to say the least and if the physics are scaled across the whole game then the downforce issues start to make sense.

I’m glad you brought this up I was just saying to myself if I compete online with one of these cars I might run TCS lol or I’m going to have to spend major time with it in time trial mode. It’s honestly a good thing to say in my opinion. I seriously think we should all meet up online and do a one car testing session!

That would be awesome! I’d definitely be all about having a test session online.

Well I've been doing the cafe menus and I'm basically staying even with the earnings; I think I'm up like 100k casue I could use gift cars so that helps. But it isn't cheap either....could be a money pit. In GTS they gave us a billion things to slow us down cause the content was so light. It's less so here, but there's still small payouts and with this RWD bug it doesn't help game progression either.

[JDMKING13]

Anothing things guys I notice from preparing for a race tonight in GTS is the throttle points are way different in both games.. I think this could also be another issue why some people are spinning out… if you are using your GTP throttle inputs lightened them up they are to aggressive.. for some reason I don’t have to be on the gas pedal that much to give it power vs GTS.

I‘m operating under the assumption that a gr3 car with upgrades will cost a million credits to race online with, and with that in mind it does seem like a very tough ask to get a nice roster to select from without using real money.

Definitely up for that. Im using TC on at least 1 now. I feel a bit dirty doing it, and like somewhat of a pleb but it gives me a little more confidence with exits. I think PD should have communicated what they changed and what they were trying to achieve By doing it.

 

[AshenGraey]

I see a lot of comments about the FR and MR cars keep spinning out. I really didn't think it was that bad until just a bit ago as I'm making my way through the licenses. The FR and MR cars are seriously undrivable without TCS. I have FFB on a higher setting on my G29 cause I like the feel of it and driving those cars with that setting makes it very annoying and frustrating to deal with because every little movement unsettles the cars and off I went. I had TCS on 3 with weak counter steering just to test things out and I still spun with the C7. I know it's sport hard tires but there has got to be a problem there

GTS had a non linear throttle, with the first 70% of the pedal travel only giving you around 30% of the actual avaliable power, the remaining 70% coming in the final 30% of pedal travel.

GT7 has a linear or close enough throttle, in line with every other sim.

Yea like I said we were kinda hit with this by surprise, I’ll tell you in AC I run TC on a lot of cars and ACC TC is always on. I wouldn’t sweat using TC in GT7 bro I think many will be using it lol!

 

[RacingFan1]

Physics seem to be a clear improvement over GT Sport, however, some things seem to be over the top IMO, and should be revised.
Braking for FF cars is quite weird, in general they oversteer, losing the tail when braking, doesnt make much sense
Also, RWD cars in general seem to be way too tail happy and way too "throttle-oversteer exaggerated". Nissan 370z for example, in that Tsukuba license test, feels like having 1000 hp. 😅

Do you think might be giving people trouble also? I’m sorry if you already said this. I just kinda noticed this.. once I backed off the throttle cars are better to deal with.

Could explain the spinning on exit, as I don’t really think about throttle application, its done intuitively, which is of course intuited from my GTS experience.

For sure, I was watching a Kie25 stream and he kept spinning out on a license and chat was saying use TC and he wouldn’t do it saying the quickest guys don’t use it. Maybe not, but spinning out repeatedly isn’t exactly quick either.

No offence, but I've never understood this vote at all.

If a car is designed around TC, then I run TC, and I've never had an issue with that.

Working in the motor industry, if I've tracked a road car or race car designed to run with TC or run it in a proving ground most of the time the TC stays on, particularly for those with stupid power levels. They are pretty much a nightmare with everything switched off.

Main point is, don't beat yourself up running TC.

Do you think might be giving people trouble also? I’m sorry if you already said this. I just kinda noticed this.. once I backed off the throttle cars are better to deal with.

I think it's a factor, particularly for those who have been primarily running GTS.

GTS is my only reference point, and TC 0 was definitely the quickest setting. The supra for example it would kick in constantly and slowed you down. GT7: I’ve just done the circuit experience for Expressway using the Supra and TC does not kick in the same way; not even close. Doesn‘t kick in with every gear change and it is possible to negotiate a turn without it flashing red at all which was unheard of In sport. It could be PD intend TC to be on. Or I could be just trying to validate my insecurity about using it lol.

FWD cars are static roughly 60 to 65% front weight bias, when you brake hard you can get up to 80% front weight bias.

That's enough to get the rear mobile if your in anything apart from a totally straight line.

PD are certainly modelling more accurate TC with GT7, it's still not as well modelled as the likes of AC, AMS2, or ACC, but it's better and more accurate than GTS.

i notice something yestersay, while setting my suspension for drifting i was shock to notice that i couldn't a drift, found out that spring,dampers,toe,anti-roll is reverse, front=rear rear=front, soo if your car understeers normaly you would lower the front anti-roll but doing this results in more understeer and vice versa, i tested this theory with the GR supra race car and the 350z z33 for drift,

 

[traind]

On game pad, I'm about ready to give up going for all gold on license test A-9 (white NSX). Somehow on my 2nd attempt I was 21 milliseconds from gold. No joke at least 50 attempts later no matter which ghost I use or what my assist settings are or controller steer sensitivity is I still can't get closer than ~250 milliseconds away from gold.

It feels like the car just WON'T TURN. The max amount of steering wheel rotation I'm seeing on screen is 90 degrees, as in the driver's hand at 3/6 o'clock stops at 12 o'clock when turning fully either way at any speed.

I'm expecting the wheel to rotate AT LEAST 180 degrees when I have the analog stick all the way to one side for a long time at a reasonable speed.

What's going on? No amount of slowing down is helping.

Several of the license tests have been breaking my balls to get gold, lol. But I have to say they each have taught me something too. One of them I was .001 second off gold and it took me about 20 more times to get that last one thousandth!

I think the one you are referencing in the Suzuka hairpin? If so, that one took me some extra effort too. Not as bad as a few others but not easy. What I learned from that one was that I was scrubbing too much speed braking into the hairpin. I had to concentrate on braking more gently and then carrying more speed through the apex.

Hope that helps.

 

[NikNakTobasco]

The license teaches you how to nail a very specific turn or turns in one very specific car. I find the circuit experiences really helpful in comparison and am happy to see them include all variations finally.

I've bought just a couple cars via the invitation and one or two recommended cars for the cafe menus. Other than that, I'm not buying any cars unless I have to until I finish getting gifted cars. It'd be frustrating to spend a cool mil. on a car only to have it be a gift car when I see no way of selling your extra cars.

I always buy the sports soft but the racing tyres are so expensive I’m really trying to avoid spending money on any of these cars unless I have to as I’ll never look at them again let alone drive them. Everything I’m doing is solely to enable me to play online down the road. I’d happily pay a one off charge to skip all this and have a online BoP mode with all the cars available. It’s really not about the cars at all for me it’s about the racing.

Million times this.

 

[driftnick13]

Yes and no.

Driving a car at 7 to 8 tenths is easy enough, driving one on the limit and doing so consistently isn't.

I should have added that getting the most out of a car is the hard part, even driving over the limits of grip in a lot of cars isn't hard, it's just slow.
