I've been using the WHQL'd 12.41's on my Geforce3 which have performed fine in Direct3D and OpenGL apps.. since Poser is for fun and not a factor in my current project, it'll be a bit before I downgrade to the 6.50's. But I'll get around to it someday. ;) Thanks for the tips. BTW armand, what version is your Detonator driver at?
