After being on my computer for a while, the FPS in games drops horribly, like from 60+ to less than 20. I can easily fix it by restarting my computer, but I am more worried as to why this is happening. I have asked some friends, and they say it could be my GPU, or maybe a memory leak. I am familiar with computer parts, but not so much on support subjects like this, so I was told to come here. Any speculations on what could cause this?
Have you checked if its overheating?
