The last couple weeks my game has started dipping into the 15-17 fps range, bouncing back up to 50's, and yoyoing right back down.

I HAD fixed it by checking "Disable Desktop Compatibility" on the boot file, but since reinstalling Windows 7 the other day the issue came back and the same fix will not work now. I'm out of ideas.

I've tried: playing in every window-fullscreen mode, capping and upcapping fps, checking and unchecking limiting fps out of window, turning vsync on and off in geforce experience, all other programs closed, and administrator mode

Please help
