As the titles says I'm having an issues with my new GTX 970 graphics card where occasionally my FPS will drop to about 100 (wouldn't be an issue in most games but is in CS:GO) and will only return to normal (around 300) when I tab in and out. I also hear what I guess are the fans on the gpu go faster or "power up" I guess when I alt tab to fix it. Anyone know what could be causing this or a potential fix?
