Re: How much graphics RAM?

Try to render the skull from a 256^3 CT scan or the output of a 3d plasma simulation and you will know *what* can be done with extra 3d RAM > (which are themselves completely useless). The major effect is, that 3d Games make 3d graphics hardware less expensive. Five years ago a SGI cost 20-30 000 $ and today you can have more 3d power for 400 $ Regards Jens > A static 3D plot doesn't > need that much graphics RAM -- it's the rapid transformation of it, to > simulate live action, that may require it. > > On the other hand, if the manufacturer's limits are that low for > graphics RAM, I would get another manufacturer.
