6.6 Video Drivers
Setting up hardware GL acceleration under Linux used to be a big deal, but modern distros should now handle this automatically. Of course there are exceptions...
Nvidia's drivers for all of their modern video cards are not open source. Because of this many distributions do not include them. If your Nvidia card is running slowly this is probably the cause and you should visit http://www.nvidia.com to download the Linux installer. In the author's experience these drivers are great, but not all versions work 100% with all cards and kernels. If you have a misbehaving Nvidia video card, try a different driver.
While new versions of XFree and Xorg have great support for Voodoo 3, 4 and 5, early 3dfx hardware such as Voodoo1, Voodoo2 and Rush are no longer hardware accelerated. To get OpenGL working for these cards, you'll need to download, install and/or compile the software libraries called Glide and Mesa. Here is a detailed README on old 3dfx cards.
