So in the past month or so I've been experiencing performance issues with my GPU. Usually games tend to run smoothly the majority of the time but every night my frame rates will drastically be hit causing my FPS to be reduced from a solid 60fps to 30 or as low as 14 during gameplay. Exiting the game does not help either. During these times even opening my internet browser becomes almost impossible. I found that when I restart my pc completely the problem tends to go away but it's become a more frequent issue. Does anyone know what the possible problem is and how to fix it. Any input would be appreciated. Thank you in advance.
