GeForce2 Ultra Video Drivers?

When I installed QNX v6.1, I selected TNT for the video driver. The desktop
looks very nice and everything seemed to work well until I tried to use
Voyager. Voyager either doesn’t display the contents of web pages, or it
gets messed up by leaving “closed” windows on the screen. I tried using
fewer colors 8~>32 bit, but nothing worked until I tried the VESA driver.
The VESA driver was the only one that could display the web page content for
me, but it’s extremely slow compared to what you’d expect from a GeForce2

Are there known problems with the TNT driver? Is there a GeForce2 specific
driver that works better than VESA and without the screen corruption I’ve
experienced using TNT?
