Crysis Warhead

Sapphire HD4850x2

Crysis Warhead updates and refines the gameplay of Crysis through a side story 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 features new fully customizable weapons, vehicles and enemies, along with new multiplayer content. It also showcases a new, enhanced and optimized version of Cry Engine 2.

Playing in “Gamer” mode automatically sets resolution to 1280x1024 and optimizes the other settings around this resolution.  Also for the testing, we left the other settings at Gamer optimized and pushed resolution up to 1680x1050.

Results: At 1280x1024, Crysis Warhead was able to nearly double the frame rate of the NVIDIA GeForce 9800GT at stock speeds, and more than double the Radeon HD 4830 when overclocked.
