Just recently upgraded to windows 10 and its never been a problem before.
theres nothing wrong with my pc specs (5820k + 980ti +8gb ram which never goes above 6gb)
my monitors are asus swift pg 278q, i think i have seen this type of flicker before. but that was on call of duty ghosts on the loading screen before entering the maps on multiplayer and only affected ghosts player window.
When i play either hearthstone, gta5 or black ops3 on my middle monitor (windowed mode) content on my side monitors flicker and looks slightly laggy. (doesnt effect just decktop background, only games or youtube videos running on side monitors)
as if their framerate is out of sync or something. (i dont know what im talking about, just guessing)
even as im typing this this, the webpage seems laggy/slow responding at random (gta5 is running in the window behind this page)
Yes nvidia driver is updated.
