You don't need GL 2.0. The most advanced feature I need to display all the rendering tricks is a stencil buffer. I avoided using newer stuff exclusively on purpose because I know how bad some driver support is.
But a more recent graphics card is always a plus although the oldest card I tested this renderer on was a Geforce 3.

Ah, I see. Well, any idea what version of OpenGL you need then?
BTW, I currently have a GeForce4 440 MX (EWWWWWWW).

I run GZDoom on a GeForce 2 without any problems.

You shouldn't have any problems with that. I never specifically check the OpenGL version but 1.2 should be sufficient.
What are your problems, exactly?`

Well, for one, the screen is not centering properly when I'm using 640x480 (my preferred resolution). In ZDoomGL I had this problem, but was able to correct it by setting gl_vid_refresh to 60. However, that doesn't seem to fix it here :\
Also, the screen becomes very dark and discolored. Normally I have to set the gamma to about 1.5 before it's at the same level of brightness in software mode. Even then, it still looks quite "off". I tried taking a screenshot, but the screenshot actually appears to be perfectly lit and colored; quite different from what I have on my screen.
Any ideas?

Adjust your monitor. It isn't properly set up for the refresh rate the game
uses. You have to do this for each refresh rate separately.
Plus, the variable is called gl_vid_refreshhz so setting gl_vid_refresh won't do anything.

If you have to go to a gamma of 1.5 to get a comfortable level of brightness something is not right. For me even 1.0 is slightly brighter than the software renderer. But this is nothing the software can do much about. As you said, the screenshot looks all right. But on the way from the graphics memory to the monitor something goes wrong.
Maybe if you posted your startup log it could give some clue.

Carn I have a feeling your running in Fullscreen Mode. Set it to Windowed Mode. I always had that damn tuty fruity effect happen with ZDooM and Skull Tag until I set my screen option to Windowed Mode. With GZDooM I have it set to Windowed Mode as well. I think on some systems the ZDooM series hates being run in Fullscreen Mode.

That's a software renderer problem. When OpenGL is active none of that code is ever called.

Ah, okay. Setting gl_vid_refreshhz to 60 fixed it.

I think I know what's going on here. See, my monitor used to be way too dark. Eventually, I found a monitor calibration program that fixed it, and just loaded the corrected settings whenever my computer starts up. It seems that whenever I run GZDoom, these settings are undone, so it's as if those calibration settings are negated.
I'm not sure why this would happen, and I'm really not sure how to fix my monitor without this calibration program. I suppose I could figure it out. But so far, GZDoom has been the only program OGL program I've used that actually messes with that :\ Oh well.

I think it has to do with the refresh rate selection. Otherwise it wouldn't work with 60 Hz and only show with other rates.
Or is it simply the gamma setting? To do gamma correction I have to override the system's default settings while the game is running.
Hpw does it behave with other resolutions?

I got the refresh rate working just fine. Setting gl_vid_refreshhz to 60 fixed that.
On the gamma issue...

That's probably what's doing it. What does ZDoomGL do for this? The gamma in that appears to work just fine.

The GL initialization code I am using is from Timmie - for the next version of ZDoomGL though but the gamma stuff looks exactly like the old one.

Hmm, strange. Odd that it behaves differently, then.
Oh well

I noticed adjusting the screen size at different resolutions had to be done on my monitor, but color brightness changes also had to be calibrated at those resolutions as well. I shifted PJ64 into fullscreen with max resolution + color (it kills my computer performance even on Zelda OoT but produces nice screenshots) and the pictures were very dark, however the screenshots I took looked just fine in my normal res.
I should also note on my monitor all brightness and contrast options are changed by the monitor's software, and not by hand dial analog. If you have digital adjustments on your brightness give tweaking those a try.
