[PC] Is tire physics/tire flex tied in FPS?

Hello,

I am curious to know if the physics of Forza 7 is tied into FPS.
I ask because I like to know the advantage of 60 FPS cap vs 60 FPS with Vsync vs Unlimited when it comes to racing?

No.

You never want to tie physics to FPS. That’s just bad juju. Never do this.

The physics engine runs at 360hz, irrespective of FPS.

The benefit of your comparisons will be input response times.
