Since a few days i bought a new graphic card ( ATI HD 7750 1GB GDDR5 ) and it works perfectly on my computer but not in league of legends... Sometimes the screen in a second appears broken and i cant play properly . Here there are some photos I posted. I keep losing games due to this problem and i would like to know if someone knows what thing i can do. The problem is only in LoL , and this is one of the reasons why i think it is an in-game problem not being compatible with this graphic card. I would really appreciate any kind of help !
