Thats a tall order, lol.
Firstly you could try my settings and disable the HD pack. I originally worked them out for smooth gameplay on a 5670@720p. If you're playing at 1080p I don't see why the 3Gb of vram would cause stutter. Someone on Maldo's forum posted the vram usage on his rig, which was 1830mb on his 6950, 1080p. I am confident he used crytek's HD pack + maldo. If the game doesn't use vram and gives load stutter then I guess I have the right to call it a poor port
Well, even with no mods and no Hi res pack, the vram goes above 3072mb just at 1080p according to MSI AB.
