I was aiming that at you, I know its not going to effect you, we haven't all got your setup and a solid 130fps. FPS will 100% have an effect on your physics trust me on that one I don't need to debate that with you.
It wont effect you with a solid 130fps, but the rest of us not at a solid 130fps its worth checking. I Even just tested it myself, turned graphics back up every time I got to T2 or the hairpins with a bunch of cars my fps spiked can see it using F and the car 9 times out of ten will end up in a slide of some kind.
I don't think I noticed it before as I was doing 60-80 mph in that little mx5 and was always in control, now though we are over a 100mph a lot of the lap I can really feel the spikes.
Now I've dropped my frames I'm foot planted through t2 for example half way through the bend and Im coming out the other end with the front of the car pointed at T3 not t1.
If it doesn't help anyone it doesn't help anyone, worth checking imo.
Anyway just got a 1.31.056

nearly at the 1.30's took a few laps at summit point(think thats the name of the track) after that. Its bloody lovely round there and a lot easier as I know the track just been tanking it around there.
This car is all steered through the loud pedal and the quite pedal, the wheels just there to aim it at the bend are my findings so far.(typical yanky car)
