[Ati]:

First, let\'s start off by mentioning ATI slightly. I have, in the pass, ran some 3D applications with the radeon DRI/DRM driver (on my  7500), however i won\'t go into that (see next url) as it was painfull, i\'m still scared. I\'ve heard that the 8500 has 3D support from ATI, however i\'ve never heard any goods or bads about it. Check the ATI tech site for more on ATI. OR:

Check this site for DRI/DRM X 3D help.
http://dri.sourceforge.net/

Note: radeon 7500 DRI/DRM driver does not support S3TC(texture compression) which is needed for games like UT2003. 8500 status unknown. Nvidia/linux drivers does have support for it.


[NVidia]:

Instead of rewriting everystep, go to the following url\'s for mostly complete info on nvidia linux drivers. Straight from the horses mouth, one might say:

Readme for install/configuring the driver and GLX.
http://ftp://download.nvidia.com/XFree86/Linux-x86/1.0-4496/README.txt

You could start from here, there is the download link and theres a link to the readme above.
http://www.nvidia.com/object/linux_display_ia32_1.0-4496.html


[Other cards]:

Goto the DRI/DRM link in the ATI section above. Your card may be supported.



REMEMBER: glxgears command is your friend, once those gears turn really fast (after seeing the nvidia logo on startup - (unless you turned it off)) it will prove your OpenGL/NVidia drivers are working properly.

Any problems or differences from the above info, howto\'s or help.
Consult your distributions website, do a search etc ...


Good Luck.
