I don't see anything obviously wrong for running P6. But a few thoughts: Check the OpenGL support on the graphics card. My experience is that you'll do better to avoid any drivers available through Microsoft. Either use the CD that came with the card, or download from the hardware manufacturer. You need OpenGL 2 for P6, or things get unstable. MS may be trying to encourage people to use something called DirectX. If your OS supports dual-core, you should at least see Poser running with all the power of one core, and the OS on the other. On 1 Gig of RAM I see a 60-40 split between Poser and Windows, so you'll probably be letting Poser have all the RAM it can cope with. I don't know the motherboard, and I made this mistake when memory could still be specified in kilobytes, but will you have to throw away DIMMs to add more memory?
