I have personally owned multiple Nvidia cards (Riva 128 back in the day, GeForce 256, GeForce2, 2 GeForce 4 (Ti4200 currently and a 4600 last fall)).
I haven't had any problems with the cards themselves nor with the drivers. But....with different video card/motherboard combinations now....that is a different story.
Ran into troubles with my GF 256 on an older Slot A Athlon board. Nothing to do with drivers or physically with the card. Just an incompatibility between the 2.
Are you sure that you have the motherboard drivers installed correctly? If you miss the AGP driver, all kinds of problems can occur. Also, make sure that you are using a current version of DirectX.
Have you played any other games besides freelancer? If so, did they show problems? If not, I wouldn't lay blame on Nvidia's drivers and black ball the company because of it. Have you checked for an update or patch for freelancer that may address this type of problem, or any graphical problem, if not specifically for your graphics card or motherboard?
That is how Microsoft came into power....people began to give up on the competition.
