So This is a pretty high end rig and it runs great, for the first 30 minutes to an hour when playing. If I am playing solo with no other applications running itll run fine, but when I play a game with discord and chrome running in the background for comms and music, after about 30-60 mins my performance has an extreme drop. It goes from, for example, 250 frames solid in rocket league to around 20 or 30 max. I have no idea what the issue could be, ide temps are around 30C and under load neither the cpu or gpu are never above 60C. When I benchmark on Userbenchmark nearly all parts say they are performing "way below expectations" I've tried overclocking all components, but nothing seems to help and I still have issues at stock settings.
