Hello, I have issues with framedrops from constant 60FPS to below 20FPS after two or three laps in every session. After another one or two Minutes the Framerate stabilizes again at 60FPS. Already tried to Verify Integrity of Game Files, Resinstall, remove DynHUD, nothing has solved the problem.
Such drastic drop may suggest something is taking up system resources in the background. Check if your HD light is flashing when the stutters happen or open up Windows Task Manager to see if there are oscillations in CPU load during gameplay and what the culprit may be.
I have checked it. The task manager shows that it usually uses 20-30% of the CPU, but during the framedrops the full CPU Usage is just 7-10%. No other programs use more than 0,5% of it. My CPU: Intel Core i7-4700MQ @ 2.40GHz
