You can't compare Farcry 2 with Crysis at graphics. You can compare them at anything else, but not graphics. Crysis is way up there at this chapter. There are the "other games" and there is Crysis. I haven't still seen a game that has the amazing image quality, the photo realistic jungles, textures, water effects, sun rays and so many great things like Crysis has . Stalker Clear Sky has some interesting graphics/effects, but it's still inferior to Crysis.
Farcry looks great too, but it lacks the image quality that Crysis has. You can compare them better during the nights and see how the scenery becomes, once you take the lighting away from them.
