I recently have expierienced some problems with my PC. When I am playing a game, which is running in 60 fps or higher, for, lets say, an hour, frame rate starts to drop to 40 fps or even lower. I noticed when that does happen, my GPU usage drops to 50% and even goes lower, while my CPU usage jumps to 100% and stays there. I have GTX 1660 and i5 7500. There could be a bottleneck, but im not sure about that. Also, im not playing CPU intensive games, like Battlefield 5. I have this CPU for about 2 months, and this GPU for roughly a month. When i put these two components together, there was no problems whatsoever. Is there anything I can do to fix this low GPU usage problem?
