In my assembled computer I am using ASUS GTX580 graphic card and I have made my computer especially for gaming. I use to play so many games in my computer like GTA IV, Crysis, fable 3 and I was not facing any issue while playing games in my computer. Now from last few days I am facing one some issue while playing games. Whenever I start game in my computer at that time the game objects and textures does not appear smooth. Please tell me is this problem with my graphic card or this problem is related with my graphic drivers.
