Do you want more detailed and realistic physics on the next GT

So,... is just FFB and wheel implementation changed or do we really have new physics?
Don’t think physics have changed but as others have mentioned the AMG Gr.3 is quite rowdy on the loud pedal so maybe the torque curves have been adjusted, also I can’t drive like the ghost in the Yas Marina Circuit experience(maybe done on a different update), so somethings different yet my previous tune PP values seem unaffected.

I don’t think it’s physics just tire characteristics have changed, throttle control and smooth application or phased application is really powerful now, coupled with the new tire sounds it’s the illusion of new physics but it’s doesn’t feel like new physics when you adjust to the new style/grip envelopes.

I will say that curbs are something I can’t put my finger feel “different”
 
Interesting. I haven't experienced straight line shake at all on a T300rs.

Are there specific cars that do it?
The Hakosuka in the Power Pack, my own R32 Nismo, the CX.R in the weekly challenge, my own EG Civic, my own S13 Silvia... unfortunately everything I've tried this far.
 
If I'm not mistaken, they typically clear previously held lap times with a physics change. So I'd assume this is just a FFB tweak.
FFB was in the notes so hopefully that’s all it is. Also cars PP would change if physics were messed with?
 
Yup, spun about 85 times on the second corner exit, almost impossible if you compare yourself to the demonstration ghost.
It’s designed deliberated to drive you to the data logger is my guess

If you look at the traces closely you’ll see the difference. I also suspect they they did that lap and sector on a slightly different build.

Edit: I just want to add that actually coasting is a very very good thing now. I promise

Didn't they announce a new tire model with Spec III/Dunlop? Or am I trippin'🤔😄
No idea what they announced but something has definitely changed and I became your namesake for a while. Coming into the first corner at Blue Moon Bay in the FF race I lost my Civic (mentioned in #6665 above) in a way I never expected, braking from fourth gear the tail stepped out and an overdone countersteering move put me into the outside wall - classic FWD behaviour, but one I've never witnessed with that car. The same continued in the infield too so it wasn't just that one corner, the car was noticably more tail happy under braking than ever before. The R32 and S13 on the other hand haven't changed.
 
Yeah, I've assumed that I'm cooking my tires at times. That's why it'd be nice for PD to implement tire temp in the UI but apparently some people here think that's nonsense lol.
Yes, I need an indicator. Especially in the DLC. Even at 1x wear, I’m feeling like I have to back off for the tyres to cool. There’s something happening that I didn’t feel in the previous update.
 
One thing it feels like what’s happening to me is either brake fade or tyres are too hot.

I don’t know your guys pace levels but honestly the noise is more prominent now on what the tires are doing.

On a practical note, it’s driving style that’s working the tires harder (and leaving time on the table) take a few slower laps to build a rhythm and it will click, honestly.

Wow. That sucks. With it being rare, and affecting so many cars for you personally, it leads me to believe it's something with your setup specifically.

I played for several hours yesterday and didn't experience anything unusual in steering.
Yup, spun about 85 times on the second corner exit, almost impossible if you compare yourself to the demonstration ghost.
I spun once on my second attempt, but once it happened I recalibrated my right foot and didn't have any issues after.

I've seen it mentioned elsewhere, but on a side note, the CGV and YM CEs are crazy easy. I've never seen a lap of, let alone driven a lap of, either of these circuits and took at most 3 attempts at each stage to git gold, and a single attempt on both full circuits.

Probably not specifically since @rtsbasic has the same problem with a Fanatec, but it may very well be wheel model dependant as your T300RS is handled by the game differently from my T-GT II for example. I'd hazard a guess that they have different driver packages for each major wheel family.

I originally thought that dropping the sensitivity from 10 to 1 would cure it but nope, no difference to the shaking, just a less responsive steering feel as a whole and that's not good. The shaking isn't violent but irritating anyway, perhaps 3-5 Hz and about 1 cm on each side. It's like the wheel doesn't realize that there's no need to apply force to either direction and ends up fighting itself.

It feels like this for me too, like the wheel wants to rock a little from left to right, persistently on track.

Had a play with wheel filter settings earlier, and in-game sensitivity, but can’t eliminate it.

Would note it’s far less noticeable on racing tyres. And not a ‘traditional’ oscillation, if I let go of the wheel it doesn’t increase this back and forth force, like I would find with insufficient damper level on the wheelbase.

Hope there’s a solution out there. In other areas the general feeling is good with more detail coming through the wheel about weight transfer and curbs. Until it’s resolved though it’s back to PC for the sim rig and controller for GT.

Watching the World Tour. Be nice if we got those tyre temp percentages.
I posted that last year. We’ll probably be waiting a while.

I’m on controller, but I’m also finding as a controller user, the trajectory is more locked in now. The path is the path. On controller, the path can be kind of manipulated if you understand me. In a tight corner like a 90 degree or something like T1 and T2 at Maggiore and Final turns of Trial Mountain, tapping the brakes can’t suddenly redirect the trajectory with the tyre physics.
There’s more real grip, more communication with the combined tyre and track surface if you will.

Agree, but I'm not aiming for gold, rather beating the demonstration ghost and topping the friends leaderboard in each sector :D

Like mentioned many times before, it's all fun, games and enjoyment until you start pushing for that last tenth...
 
Force feedback is definitely different

Easier to catch the rear and perhaps more details from the road and kerbs, hard to compare from previous versions

I also feel like the tires behave differently, again, hard to compare to a previous version
I agree too. First thing I noticed is the small resistance added to the wheel with road cars. You cannot miss it with the FTO. If you use your senses a bit, it really feels like driving an FF car in real life. If you spin the wheels while turning, the car wants to keep going in that direction as long as you keep you foot on throttle. Release it and the wheel straightens and you feel it in the wheel also.

Cars in general feels more balanced, easier to control but in a good realistic way. But you still have to practise and be smooth to get good lap times. It does not make the game easier.

Stock 296 is so easy drift and maintain that drift. A pleasure to drive. Usually, i have a hard time drifting cars since GT5. Drifting the 296 honestly brings back my GT4 drifting muscle memory and it works.

Mines Skyline suspension is so bouncy but stiff at the same time. You can feel it by upsetting the car on curbs, especially at the CGV. Gr4 Lexus did the same there. But in general, weight transfer feels really good and predictable. I guess we have to not abuse the curbs.

Overall pretty engaging to drive and fun at the same time. Now time to test the old cars and tracks to compare.
 
After reading some of these comments about the CGV circuit experience I was dreading it, I haven't really been on GT7 for a while, did the last 2 TTs for some money ready for this update but that is all.

But to my surprise, I thought the AMG was brilliant on CGV and had no issues in golding it, I don't even know the track at all either.

I haven't tried drifting yet to see if that has changed, but I think it feels better now.

FYI, this was on motion steering, haven't tried the wheel yet.

They announced a "partnership" with Dunlop, but it really is just a product placement, replacing Michelin logos with Dunlop ones. There was no mention of a new tire model. So yes, you're trippin' :D
Haha, maybe, but not completely😄
An GTPlanet article from back in September when Spec III was announced:

"Alongside that we’ll see the introduction of the new Dunlop tires, developed using data from the new partnership with the Sumitomo-owned tire brand. This will likely mean a new physics model to adapt to the new tires model too."

Looks like the author came to the same conclusion as me. Of course, because if nothing has changed, then what has been "developed using data from the new partnership with the Sumitomo-owned tire brand"? The logos and looks?

Sorry but, what does "coasting" mean here?
