My guess: you have video on the motherboard and a separate video card, and you connected your monitor with the first now in stead of the second.
Ok, so I moved my PC to a different house for a little while and I tried to run a game on it and experienced a massive drop in performance in games I usually run completely fine and it was so bad I can't even play them. This isn't just in one game either it's every game I play. I have no idea why/how this is happening any help is appreciated ![]()
