not that much sum guy tested several games on it most fast action games like faer stalker and assins greed played great (so far from what i could understand) but with assins creed at one sort of temple he had a problem of sum blur but he wasnt sure if it was the game itself or the monitor but he thinks its the game hey says the coloursare amazing espicially with stalker when he palyed at 1900x1200 he felt he was really in the game it showed how much WOW factor this monitor has caus of its size and high contrast.. thats what i could understand so far...
