P6 has an openGL workspace (finally, geez), which does put some straiin on your GPU. honestly, i dont see much of a difference at all (you could just disable it in the settings). but, i'd have thought that a mx4400 would be enough to run it. i mean its basically a rebadged geforce2 GTS, and i used one of those to run 3ds max's openGL workspace for years with no problems (of course i may have modded the card into a quadro, dont remember). anyways, this is why im asking about the system specs. perhaps the slowdown is due to other reasons. for all we know the original poster could have 128 megs of RAM, or running it on win9x, etc.
