Hi... Whenever i try to start a glide game it wont start.
For example: When starting concole in half-life its just "loading" and nothing happens.
Diablo II video test just get stuck when testing glide.
disabling SLI or switching PCI-slots dont help. I have istalled mip-map error fix but nothing changed.

My system is:
Intel Pentium III 530 Mhz, 448 Ram, Radeon 9250, 2 V2 SLI

I had the same setup on a 1Ghz and never had any problems...

Try to uninstall all the drivers of Voodoo2 of your system
Download and install FastVoodoo 4.6 if you have Win9x or FastVoodoo 4.0 Gold Edition for WinXP
Check if games works. If doesn't, install this Voodoo2 driver: https://www.3dfxzone.it/public/uploaded/koolsmoky/200762465834_Voodoo2.zip

However, tell us what is your Operating System, and what drivers have you used.

Half Life has 2 options : Direct3D or OpenGL. This game is not a glide game.
