Hi, I have just downloaded the latest drivers for my GForce card from NVidia (Version 52.16) and now I can run openGL. It works very well with the only problem I have seen is the item tag leaving a white space in the render to screen box. but I don't think that will be a problem. If you use these video cards and don't use opengl you may wish to try these drivers. I have not tried a very large scene with lots of toys in it but I'm happy at this point as it is as fast as the wireframe mode on my 1 gig computer. have fun Neil
