I'm running Windows 95 OSR 2.5, directx 7 and the 30100 reference drivers. Changing the gamma settings in the display settings doesn't work at all. Default is 1.7 and I've tried changing it to everything between 2.0 and 0.1. Yes, I have the 'change gamma in glide' box ticked. I've also tried manually setting it with a batch file (SET SST_GAMMA=1.0). I tried a different Voodoo 1 as well. Nothing works. I'm out of ideas at this point.
