I'm particularly annoyed that they didn't add native AA support. The only way to have antialiasing is to use Windows and use the nVidia/ATI driver utility to force AA on. Enabling it in this manner kills performance big time though, it is *far* better to have it enabled straight in the game. Even with a 5970 in Windows 2xAA makes the game unplayable. For a game with such middle of the range graphics that's simply ridiculous.
