Say I'm playing Dying Light on my NVIDIA GeForce GTX 660 Ti. I get into the game (with about-low settings) and get about 60-80 fps with little to no dips. After about 10 to 15 minutes, my FPS will drop to 20. Is that due to my GPU overheating? Is there a way I can change the overheating temperature before that cool down mode initiates? Thanks (ahead of time)!
