Crysis runs better on Windows XP
 

Crysis runs much better on Windows XP than on Vista and this is a real shocker for us. At the development stage you will get severely worse performance from a Vista based machine than from Windows XP. This affects both Radeon HD 2900 and Geforce 8800 owners and there is only a hope that Crytek can fix this until the launch.

So we got one more thing for a Nelson "HA HA" moment with Vista users?
