GPL gamma control problem

I hope someone can help me ! I'm running GPL on a Voodoo3/2000 AGP card with the latest drivers from 3dfx on a Intel P2 350mhz sytem. The game and Voodoo card runs fine but I'm unable to get the game to react to the Display Control gamma adjustment. You can see that the control has an effect because the 3DFX splash screen gamma does change with the adjustment but the game doesn't react. Any suggestions ? Thanks and Cheers !

In the display properties dialog, you can adjust gamma correction seperately for 'desktop', 'D3D' and 'Glide/OpenGL'. Did you select the 'Glide/OpenGL' box before adjusting the gamma settings? -- Wolfgang Preiss \ E-mail copies of replies to this posting are welcome.

I and a few others experienced this problem when we bought Voodoo3's this summer. Regardless of what I did in the 3dfx tweaks my display would still remain dark (making it difficult to race on circuits with black tarmac). I have never been able to trace the exact cause of this problem and it also seems to be one that affects only a small number of people based on Usenet postings. I don't think I've even seen the problem acknowledged by 3dfx. Nevertheless, there is a solution. I found an old version of GLIDE2X.DLL for the Voodoo Banshee card (dated October 98) that responds to gamma controls properly. All you have to do is copy the file into the same directory as GPL. If you can't find it anywhere, I'd be more than glad to send it to you. Martin ?Viva Mansell!
