I'm trying to play a game on VMware Fusion (using windows xp). But I get this message: "3D acceleration requires features that are not present in your Mac's graphics processor. You can enable 3D acceleration, but some programs may not behave as expected, or your virtual machine might unexpectedly quit. If you encounter problems, disable 3D acceleration." The game runs, but with terrible lag. Can I fix the problem by upgrading my video/graphics card? I have a white Macbook 2.2 GHz Intel Core 2 Duo with 2GB of memory.
