I am able to run all the games with no problem and FPS is fine etc. its just that when I play any game in windowed/windowed full screen like for example h1z1 and league of legends the screen flashes/waiting to respond every time I click my left button more than twice/spam click? Also when I play in full screen and alt+tab the game crashes and I can't alt+tab back into it? I figured out that if I go into full screen mode on league of legends then back into windowed mode the flashing problem doesn't occur on, but every other game there is still a problem.. I thought it was something wrong with my GTX 680 so I bought a new R9 380X and this problem still occurs? Please help!?
