Hey Mitch, The deal is that the interface itself is completely done in OpenGL. I assumed that just about everyone had a video card that supports OpenGL. Tell you what, send me an email at konan@sympatico.ca and I will return your email with a special build of the Extreme Morph 3D demo that does not use textures in the interface. This may be the cause of your slowdown, and a tetxureless interface may solve your problems. If so, I will enable an option to turn them on and off at at will, and perhaps "auto detect" a slow refresh and offer to turn them off automatically. Konan
