Gran Turismo 7 Physics

[Greycap]

It’s pretty poor of PD’s own QC and house keeping if they don’t have a default config file they can just revert to for wheel traits and settings in cases like this. I’d have expected each car to have a set config per input device (dead zones and basic calibrations) they can go back to if some one put the wrong config in the gold version of the update.

Probably not a case of a bad config, that car has always been noticably subpar what comes to the FFB. It's just that the current physics amplify the issue even more.

On fanatec dd+ i dropped my nfr to zero snd found the wheel went lightish and the tire alignment was easier to feel. Did it on the Honda in the TT though.

That's very likely caused in part by the tyres used. Nobody else than me runs it on comforts but still, racing tyres are so wrong for it that I simply refuse to take that route.

The tyre selection may even be a big reason for the entire problem, it feels like the fronts don't generate enough lateral grip to give proper alignment forces but it's still wrong. Admittedly the front of the car is very light and the tyres have next to no grip, but then the steering should be without feel and extremely light instead of the weird "fine grain sand in all ball joints" feel it has now. Or has always had, more or less.

If anyone is having trouble or wonky FFB on the T598 after the 1.71 update try BLUE mode on the base.
After some testing and fiddling with settings turns out RED mode is no bueno, the wheel was very heavy and lazy regardless of how much torque I was using and it was not self centering like a car would do if you let go of the wheel during a turn.
Hope a fix will come soon either from PD or TM.

Using a pad I’ve found some cars now feel horrific, some now feel great. One of my favourites, the F430 Scuderia feels wallowy, yet my 98 Civic now feels even better. It’s really hard to work out whether it’s physics at play, or changed stock set-ups.

This may play a large part in our findings. On a wheel the self aligning torque is just about non-existant, it's not a common problem but this car suffers from it a lot. To the extent that it needs nearly as much force to countersteer than to actually steer, thus the mushy feeling in which it feels like you're just turning a shovel in a bucket full of loose mud without much if any actual feedback from the car. When the tail steps out the wheel doesn't go light or begin turning the other way like it should almost at all, making catching slides unpleasant guesswork as it doesn't communicate through the wheel when the tyres are tracking straight again.

But, I took it for a spin too. Otherwise a full stock car but the tyres and a livery, no doubt it could benefit from a few setup changes but this is how PD intended it to handle - with the exception of the tyres. I actually think comfort softs are still far too grippy considering what kind of plastic they used in the sixties, it's worth noting that it was common to do more than one race on one set.

Gave it a try. Just finished a few laps with the RA272 all stock except CS tires around Suzuka.

Firstly, what are you talking about?? I didn't sense anything dramatically strange with the car. I did notice that in heavy braking the resistance of the wheel lessons a little bit, but returns once easing off the brakes. I had no problem at all anticipating and catching oversteer and the counter steering felt totally natural. In fact this car responds so beautifully to trail braking, you can hold a nice long oversteer into turn 1, "backing it in" just like you see vintage race cars do around Goodwood IRL. It's actually fabulous.

Maybe because I'm using a G29, which is well known that it can never countersteer for you so I'm used to it. Is it an issue you're discovering with higher end wheels?

Secondly, this car is so much fun with these physics! See above about backing it into a corner.

Have these people ever driven a performance car on a track at high speed? Or is the only experience they have is behind a sim rig?

The physics are objectively light years better compared to what we had.

Most e-sports players prefere learnable high accuracy demands, that they can learn and master. Prefarrably things staying the way they have already mastered. Things changing from proactive to reactive is never their preference. So few grains of salt is always needed with their opinions.

That said - the fast seem to still be fast.. adapt and overcome.

I agree that something is very wrong with racing tires, the amount of grip they have and the steering angle I have to input to use it all just feels wrong.

Same here - I’ve been testing out various and saw the post so was curious. On CS tires I was having a lot of fun - it really felt like those were appropriate to the car and also very natural. The grip limit was easy to balance using the throttle

Tried the SH as well and they add additional grip but not overpowering and a bit less fun

DD+ running the auto setup at the moment

Really happy w this update, but the Race tires could be a bit narrower in the slip angle and a bit less grippy longitudely, but not by much - just some tweaks

I haven't tested it extensively and I haven't been playing gt7 much. That said, in gr3 no TCS seems like tcs2 in the previous version, but in gr2 doesn't seem that different. Curbs unsettle the cars more than before and you can turn the wheel a lot more. That's what I was able to notice using my g29.

I still think the ffb in the g29 is not very good, the cars are still on rails and it lacks nuance. Not much different than before. Based on what people were saying I was expecting something like the jump with the 1.49 update before they reverted it.

I'm glad they keep iterating to try and make it better. And I hope they keep on doing it and do it with other aspects of the game (like bigger grids, more sophy, new UI, cof cof).

While the positives outweigh the negatives (although I'm biased towards road cars with non racing tyres) the ability to steer beyond the understeer limit is really immersion breaking.

So, has anyone experienced this with the new physics?

I was driving a stock FTO with a few power upgrades - no tuning. And, hitting the brakes not only lifted the rear, it almost got me airborne...

yes, the same here
