Hi, I've been having this problem for awhile now and I've tried pretty much everything in the book at this point (everything simple enough anyway). My computer repairman couldn't diagnose the problem which worries me. Anyway from what I understand, my motherboard is becoming too hot and is causing the FPS to drop. I remember testing this awhile ago with software people recommended. My PC is more than capable for running the game I'm testing with (I will leave the specs in the post). My computer also has decent cabling, along with water-cooling and 4 fans; I've also cleaned it pretty thoroughly at this point.
Recently while playing Dying Light for about 10 minutes, my power supply actually fried. That's why I ended up going to my repairman, of course he just replaced the power supply and gave me a power surge protector and I'm afraid to try again at this point - surely this is part of a bigger problem. Sorry if I'm rambling at this point, I'm just looking to fix this, thanks.
