Hey, I've recently been having FPS problems when playing games that I usually can run fine even dropping to low fps when its all on low detail. I've been monitoring my system usage and I think its a CPU problem, it'll either use 100% and start dropping to low fps or the usage will go down to like 30-40% and it'll drop FPS as well. I've tried running multiple virus scans and updating all drivers and cleaning out old files. I'm about to clean out the dust from the inside of my pc to see if that helps.
My specs are:
i5 4690k
GTX 970
8GB Ram
Windows 8.1

temps seem to be pretty normal GPU at 56 and CPU around 40. I have Rust open the game in the background and my computer is very laggy when it alt-tabbed trying to write this message
