Made a Windows XP x64 virtual machine (allocating 4 cores and 4GiB of memory) in VMware Worstation 8.0.1, installed newest VMware Tools, updated Windows, updated DirectX, and copied my Crysis Wars crap over.
Here is MWLL running at 1440x900, no AA/AF, all HIGH in game settings, except particles which is medium:

Had a solid 30-70 fps the whole game, except the occasional loading/zooming pause. There was some minor texture corrupting and a bizarre shadow bug that made it seem like as small could was following me around, but the game was totally playable and looked pretty good. I'm sure I could improve things further with some more tweaking.
