Hmm, I tried to run on a Dell Inspiron 8200 laptop computer:
winXP, ati radeon mobility 9000 64MB, 1GB RAM, 1.8Mhz P4, latest dell ati drivers…

Its running quite well relative its a laptop, but there are some annoying issue:

In the parameter window if its not fit to it, (the scrollbar visible), it doesn't refresh when I switch to an other category (e.g from transformation to shading), if all the parameter fits to the window pane then its working fine.

It should be some double buffer issue, when I switch off the double buffering its working well, but then the 3D viewport looks awful during any interaction.

Xray function has no effect at all. (in Maya xray working well on the same machine)

any idea?
