Hello, I want to know if someone else has stuttering only when contact with the AI cars, even when the AI contact itself. Isn't a FPS problem because my FPS don't go down, but I get stutteing. Also, I was trying to get contact with a wall for exemple, and I got stuttering too. I don't know what happen in my computer with the contacts, maybe some damage calculations produce this problem. I don't know. My test was with GT3 cars in Spa and Zolder, with 32 and 64 bits Before the December build I didn't have this problem Someone can help me? thanks!!!
