When I open up a game my frames are normal, usually I get 200+ but 10 minutes later my frames drop to 30-40. When I open up Task Manager it goes back up to 200+. So I'm really confused to why this keeps happening. I have to constantly leave Task Manager open when I play a game. I've been searching around and there's people with similar problems. The replies I've seen is that there's a mining virus. I downloaded Malwarebytes and tried to play a game after, but I still get the same results.
