Game runs perfectly (80-120 FPS with maximum video settings) until about 30 minutes on, then it's limited to 30 fps, needing a Windows restart to come back to normal state, just to repeat the same process. Changing video resolution or video setting don't have any influence about it. I have disabled Xbox DVR, and the "HP CoolSense" is turned off, as well as I'm on "high performance mode" with A/C conected. I've performed a recovery for OS, so no malware/virus should be the problem. What else could I do to fix that, guys? Really need your help.
