Crysis

Crysis – DX9

Notes

Crysis performance is pretty even across XP, Vista, and Windows 7. Again, the GeForce card takes a slight hit under WinXP x64, the GTX 275 runs about 4% slower under the 64-bit version of Windows XP, but everywhere else performance is pretty similar. In fact, the SLI setups run 2-4% faster under Vista and Windows 7 at 1600x1200, and that margin grows to 7% at 1920x1200. If you recall Vista was the first Microsoft OS designed from the start for multi-GPU setups like SLI and CrossFire.

We saw similar behavior with Radeon 4890 CrossFire. In fact, CrossFire consistently ran 12% faster or more under Windows 7 than Vista.

CrossFire scaling in Crysis has been a thorn in ATI’s side ever since the game was launched nearly two years ago. Perhaps with Windows 7 that may be a thing of the past.
