Crysis Warhead updates and refines the gameplay of the original game through a sidestory plot involving Psycho, one of previous protagonist Nomad's allies. The game is a parallel story that follows Sergeant Michael "Psycho" Sykes, a character from the original Crysis, as he faces his own trials and challenges on the other side of the island during the time period of the first game.
It also showcases a new, enhanced and optimized version of CryEngine 2 using full DX10 extensions and is the first game developed by Crytek's Budapest studio.
Compared to the single HD 5850 we see some very good performance gains. We weren't able to achieve a 30 FPS minimum with one card, but adding a second sees us achieve a 30 FPS minimum at both 1680 and 1920. At 2560 x 1600 we're only a few FPS away which a small detail drop would fix.
