Dear KiFe
Like MANY other people, you have problems with your GeForce2 graphic card. What makes me think so? If Softimage is properly installed, using a legal license of course, there should be no problems with the software itself.
The GeForce is an extremely powerful card, and the price is now very reasonnable. BUT it is totally crap when it comes to Softimage. You are one among so many to have problems with these stupid cards. I too own a GeForce2 card, and I too have problems (too many to list).
I know that many users of GeForce2 card will object on what I said, but the fact is, based on personal experience (forums, mailing lists, friends and co-workers), they are minority. I tried many hardware and software configurations, with the same results.
I spoke with Softimage's Technical Support, and what they told me is that Nvidia doesn't care about their GeForce2, they care only about their GeForce 3 and their Linux drivers. So don't expect any improvements to your problems.
Besides that, have you done the normal checkup things? Like reinstalling your grapic card driver, downloading the most recent one, trying another card, reinstalling Softimage, reinstalling Windows, trying your card on another machine with Softimage, and the like?
Sorry to give you bad news. The next purchase, in my advice, should be a 3DLab card. That's my choice for an upcoming card.
