I played through Deus Ex on mine. Game looks great at 2560x1600 although there is banding in the textures which is not the fault of the monitor but rather the art team. I don't detect any input lag. Finally, the cutscenes look worse then the game itself because they are at some stupid low resolution. Again, not the monitors fault.
The only issue I have for FPS games on a large monitor is that due to the immersion factor I need the framerate to be a smooth constant 60 with no stutter else I get motion sick pretty fast which requires an investment in graphics cards.
