I recently started having some problems with games running on my pc, for example they would play normally as they should and then after a few minutes of playing they would drop by twice the frames i had before, that eventually just went away but now they slow down at the start, for example in rocket league the first maybe 2 minutes the game runs at around 15 frames per second and after that plays normally at 60 as it should. But with other games with higher requirements like fallout 4 or gta 5 they will play at around 15 frames and just play like that no matter what settings they are on forever. I installed no updates or any software when it started to happen so I'm starting to think its a issue with the hardware. Can anybody help me troubleshoot what is wrong with it?
