@platymusPrime just took the physics update for a test drive on my lunch break. Spoiler alert, its much much better.
I tried the new BRZ at Tsukuba on SH tires (stock tires), the loss of grip on the rear wheels is much more progressive and you can catch the slides more easily, its still a bit hard and snappy but nothing game breaking like before 1.13.
Also went for a drive with the C6 ZR1 on SH tires too at Trial Mountain, turned everything off, I was driving with ASM on and TCS 1 at all times before 1.13 and now it was a blast. It was still a handful, like you expect it to be but its drivable and so much more fun now.
Compared to racing on GT Sport last night, you really feel the improved FFB on GT7 IMHO. Can’t wait until the fix the lobbies, C6 ZR1 on SH tires @ Trial Mountain would totally be in my top picks for a combo.
