Which graphics card are you using? I have the same 
experience, and posted a note to this newsgroup a few days 
ago. 

I am using an NVidia 8600GT card with 512MB of DDR3 VRAM, 
and the card performs poorly on MATLAB's graphics benchmark 
(which does a 3D rotation of the MATLAB symbol). 

The card turns in stellar performance on Vista graphics 
benchmarks. I don't understand why it is slow in MATLAB 
(and a much slower ATI 2400 HD card turns out to be faster 
in MATLAB, but slower on Vista graphics benchmarks!).
