View Full Version : Gamma Problems with NVidia TNT2 M64 on Win2K

03-20-2001, 04:57 AM
We have four Dell PCs with NVidia TNT2 Model 64 cards, all Pentium III's running Win2000.

Several games that use OpenGL (Quake III Arena, Star Trek Voyager: Elite Force, to name a few) have extreme gamma issues. The in-game picture is DARK! When you adjust the brightness settings, it hops all over the place but basically the games are near pitch black.

We have tried using the in-game console commands (r_intensity/vid_restart) but no setting looks good, they don't "stick," and while you can brighten up the image, it becomes contrasty & glaring. It's awful.

We have upgraded and downgraded drivers for weeks and nothing seems to work.

Can anyone help? Thanks in advance!

I had a similar problem trying to run Quake 3 on a Dell GX150 (Win2000)with a built in TNT2 card. I loaded the latest TNT2 ref drivers (6.50) and that didn't help. What does seem to work is to run Quake 3 as a window rather than full screen. Adjust the Quake resolution so the window is as close to full screen as possible.

This isn't a high tech solution, but at least I have a playable game. Maybe somebody else has a better idea.

Strangely, running in a window works! But the frame rate suffers badly. This has to be a buggy driver problem... something must over-ride a setting when running in a window. Frustrating!!!

did you have any problem getting the game to run at all? Im useing a nvidia GeForce 256, it's a very similar card to yours, but I cant even get Quake III to start.. I keep getitng "can not load open GL subsystem"... Im running Windows Me, a Athlon Processor, and a 64mb Geforce video card.. if you did have that problem, how did you fix it? the latest Nvidia drivers, open GL drivers and the Quake III patch didnt help..
