Ok , it;s becoming even more weird. All tests done after a steam integrity check with vsync off and shadowplay off. AI cars 12, sitting in pits. Matsusaka 3rd line is cpu load at all 4 cores. GPU load is at 5th line, most right number 1. Visible cars 70 , good fps but why not GPU at 99% instead of 69,4%? 2. Visible cars 30 , bad fps , way less than 70 cars??? 3. See AC with 12 AI cars and vsync off GPU load at a healthy 95% Please explain this to me. People read 1st, answer later ok?
