I guess nobody knows the answer?¿

I'm wanting to upgrade as soon as possible but having a hard time finding out just what Windows Server 2003 has to offer in the way of support for Direct 3D, OpenGL and even DirectX. I know they are supported however, how well do Apps that use the technology run or how much do they suffer.

If anyone knows anything, is running or has run any 3D software, pleeeeease let me know.
