This issue still exists in Fusion 6 and Mavericks. Please consider implementing OpenGL support soon.
VMWare Fusion with Mac OS guest is a very useful tool for developers....
No virtualization solution provides 3d acceleration for OSX guests (any OS version). I know it's on the list as a highly desired capability, but it's also much much more complicated than providing it for windows because of the architecture.
Best option for 3d is dual boot at the moment, unfortunately.
