Kemal... I've been working on this castle for a few weeks in Maya, no glitches whatsoever. The only thing I can't do is hardware rendering, but the only thing you would use this for is particles. The NV17 doesn't support pixel shading extensions, although it all worked fine in Maya 6. Notice, though what else isn't on the list? ANY other graphics cards made in the last two years. So this list is two years old, regardless of what Alias says. They haven't bothered testing any Geforces since my card. And the newer cards, the 5's and 6's, are exponentially more powerful than MY card. So in the last two years, NVidia has updated their drivers... five times? Maybe six. This report doesn't reflect any of these updates on a Geforce level or even Direct X 8 OR 9! Suffice it to say that I have no problems playing FarCry, pumping out massive amounts of texture and T & L data. So a few million polys, untextured as they are in preview mode, are butter in Rhino and Maya. I've never used any polygon reduction on my castle, in Bryce or Maya! At 512 RAM, Bryce just cannot deal with it. Maya has no problems that I've run into, in either it's software renderer or mental ray. Sorry for hijacking this thread or whatever, though...
