Gran Turismo 7 Physics

[CodeRedR51]

Just spent the last week perfecting a tune on one car, and now I probably have to do it all over again. 🤣

I can't figure out what's really different. I think the cars are more predictable now which is good?

I can't seem to figure out what they did to the LSD though since I'm totally blind when it comes to LSD tuning.

Suspension geometry is something that just exists. You don't get to change it to whatever you want. So this means it was a farce before or a farce now? They aren't working with real data? Kind of a red flag this far into GT7's existence. Clearly there are issues with their physics if this far down the line they have to start redrawing geometries.

MR Gr3 cars.

Have these had a change in the new update? I’m really struggling now with these cars in the slow corners with the rear snapping.
RBR T3
Spa T1, and the bus stop chicane
Deep Forest at the hairpin.

Ive not set a lap time in the Daily C TT so struggling to compare my laps times.

I don't know about predictable, to me it seems less predictable. The brake balance seems to have more of an influence now. And the lateral weight shift seems more pronounced, so you need to have the nose pointed down in the middle of a corner to not understeer off the track.

This update feels less natural to me, something seems to be off. Even when looking at the replay of the McLaren F1, the car/suspension doesn't seem to move like it should.

I haven't really enjoyed the handling thus far, the cars don't quite do what I want them to do. It feels like a struggle. Even though my laptimes are 2+ seconds faster.

But this is my first impression, maybe I'll get used to it later.

Not sure about an improvement. My tuned 240ZG darts all over the place with change in direction. It’s has front and rear aero with RH. Always drove fine. Now, off- throttle in a curve, the rear is slowly rotating and when I correct, the front is snapping and I get a sawing effect. Didn’t record my races as I’ll see if my other cars feel different.

Knock knock, physics changed, you shouldn’t expect your tunes to work the same way they did beforehand

Is there really a need for snide comments towards people? Everyone is experiencing this garbage on their own terms. Now is a time for comforting and condolences.

Maybe it's because of the camber being at 3.00? Someone mentioned all their tuned cars have 3.00 camber for some reason, I did see one of my cars have that too.

I don't know, I have mixed feelings for this update.

FFB have been fxxxed up again.

Feels dead and worse than before. This is a fact.

I think someone above mentioned "improvement'. Hence, why I mentioned I don't know about improvement. As it clearly wasn't an improvement I experienced.

The cars I ran are fully stock, maybe they changed the camber, didn’t bother to check the settings. I ran the f40, 92 nsx and the F1.

I see, I haven't checked those cars.

I've seen quite a few posts on Reddit saying street cars are a bit screwed now, too loose and floaty while the race cars seems to handle better.

 

[BigSarj]

I can't be bothered to turn the game on since the update when I have PS+Extra games to play instead but if every car has 3.00 camber, surely that's a bug, no?

 

[Omiyup]

Everytime I finished perfecting tune

It's weird though, some cars did get improvement like the Corvette, but others aren't.

Update: Drove the same car with the same setup at the same track I was testing at previously, and ran 8 tenths faster. Car felt fine, I didn't really have any complaints. Maybe a touch more corner exit understeer, but the off throttle corner entry was actually better than before, so that was a plus for me. The car stepped out once and was easy to catch. I also noticed that the force feedback was a bit stronger, you can feel the car move around a bit more. Bottom line, no complaints from me.

 

[BigSarj]

I don't understand how some people say the ffb is better and others say it's worse. Every update, damn near everything that one person says is contradicted by another. What's strange is that is the only thing wanting me to boot up the game these days; to see for myself.

I wouldn't really say it's better, but it's....different.

It's just adjustments. No game gets everything perfect. Braking in iracing for race cars is not similar to ACC, in which ACC is similar to GT7 in this regard. No one is red flagging iracing for this. A lot of these games are still good references for what to expect irl.

Changes are fine. It sucks to have to re-do settings after each update, but if the physics changes are actually good and make the feel of the cars better overall, then they can change it as much as they want.

Changing suspension AGAIN?!?! Hey here's an idea PD try SIMULATING the real world in your SIM, then you wouldn't have to keep changing things.

IMO this continuous meddling proves PD have no idea what they are doing and GT7 was not intended to be and never will be the REAL driving simulator. Sounds to me like they have a committee running things at the top. They should get into British politics.

I’ve been watching a lot of ACC on YouTube.com as well as playing a little of it as well. It’s amazing how similar the braking points and general lines are. What separates GT7 and ACC simply is the physics. In GT, you can still absolutely murder the kerbs. Not to mention, you watch the leaderboard laps for GT7 daily’s, and those guys are sometimes full on n drifting through corners. Brands hatch last week was a perfect example of that. I think these aspects is where Gran Turismo still could use some work, but all the while still staying in their respective “sim-cade” lane

As has been mentioned before no game gets everything perfect hence developers are always changing things. It's not just a PD thing.

ACC for example recently had a tyre model change and physics change on console but that doesn't mean the developers have no idea, it means they're always looking to improve.

Version 1.8 of ACC allows you to attack the ripple strips and curbs a lot more now.

 

[05XR8]

To be fair, I left the set up as is(I’ll have to check if any settings were adjusted). As I mentioned, my settings are already camber: -3 f/r, ARB is 5/5-7/7, depending on car. Springs are 3.0 f/r. Dampers f:25, r:45. Standard fair for PD settings.

 

[Yard_Sale]

I agree. It’ll still punish you if you do some of the cuts we’re accustomed to in GT7 tho. Really getting into that game

That's what they have been doing and imo they have come close with this update. At least for me I'm driving with a big grin since yesterday morning.

(mostly time trialing stock road cars on SH tyres with no driving aids - which includes no ABS, everyone should try it)

 

[F30clubman]

I can't seem to figure out what they did to the LSD though since I'm totally blind when it comes to LSD tuning.

The fucntioning of the LSD has been bizar since GTS. Try driving GTS again in a stock FR road car (with LSD) e.g. on SH tyres, and then compare the same car in GT7 now. Give full throttle in mid corner. You will feel the difference. Some examples you could use I would suggest the '02 RX-7, the S2000, an old Shelby Mustang with LSD installed (it does not have stock LSD in the game but had one IRL)

Before 1.25 and in GTS the rear axle moves magically outwards under torque (even in low rpm on some cars) without any feedback about tyre slip. This is impossible, as the strong sideward movement goes beyond tyre deformation and that means slip.

Since 1.25 there is feedback about tyre slip (sound, car roll movement) and the car reacts when tyre deformation turns into slip and when slip turns again into tyre deformation. I'd say the loss of lateral adherence is now also bound to power instead of torque which imo is correct (try IRL to make your RWD streetcar loose rear grip in a corner: you will instinctively gear low and rev the engine, and not give full throttle in a high gear).

This improvement makes imo driving GT7 a little more difficult but more natural. I think it's quite courageous of PD to go this way as GT7 evolves more into a simulator and away from arcade game. Which some people will not like probably.
