Recently I have been getting terrible performance on games I used to be able to run flawlessly. I cant even use my VR headset (like I used to) because of my PC's terrible framerate etc. So I checked my task manager and applications were taking an insane amount of CPU power and when my pc was idle it was still using up to 95% cpu and 80% memory. I've tried everything online and I almost resorted to wiping my hard drive and getting a fresh install of windows. My friend with almost identical specs can run much more intensive games than me on higher graphics settings while still sitting at double my FPS. Any thoughts other than a defective CPU/memory/motherboard? My computer is about 3 years old and I just bought new RAM a couple weeks ago. Im running windows 10.
