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. The screenshots that we posted yesterday are
done at 1366x768 on a super overclocked 3.4+ GHz machine with 2+GB
memory and a heavily overclocked Radeon HD 2900XT. Even with such a machine, you still get 20 to 40FPS.
You can expect a slightly better FPS values
from the XP machine since this demo is optimized for XP, but it does
run on Vista. Remember Crysis is suppose to be DirectX 10
breaktrough game and it should run on DirectX 10 and Vista much
better.
