Plutonium

For the past few days, my Black Ops 2 (Multiplayer) has had very low FPS, ranging from 2-10 fps, even though I normally have 220-240 fps. I've tried the solutions on the low fps guide, disabling fullscreen optimizations didn't work, but when I set it to high performance, it worked for like 2 or 3 games, but then went back to running at 2 fps. Does anyone have a solution? I'm on a laptop if this helps.

I use DS4Windows, and my controller was working a few days ago, even in the menus and stuff, but now all of a sudden my controller doesn't work. The only thing that works is the touchpad, and all it does is work as a mouse. DS4Windows/my PS4 controller works on all of my other games though. Does anyone have a solution?
