G400Max, Quake1, odd color artifacts

[fury]

A picture is worth a 1000 words.

I would post a pic (gif) if requested, as it is very difficult to describe the problem which only seems to appear in Quake1.

I get very odd shadings of surfaces, but not of all surfaces. The colors seem to be not of those in the Quake1 palette.

I have installed bios 1.09. Using drivers version 5.52 from Matrox. Tried 5.20, but got a "not recognized card" message.

Help!

Stuff:
Asus P3V4 bios 1003
VIA 4in1 v4.17
2pcs- Micron 128Mb PC133 ECC (256 total)
Intel P3 550e @733, Alpha + Peltier cooler
SCSI drives
Diamond MX300 sound card

Half-Life, Quake2, and Unreal Tournament work fine.

You are most probably seeing the 'rainbow textures' effect. We have been seeing that since the first ICD beta. Hopefully it will be fixed in the next release..

To go around it, just add -lm_4 parameter to your GLQuake/GLQW commandline.

Another option is to set the console variable:

r_dynamic 0

That turns off the dynamic lighting which is the cause of the disco lighting effects..

[Shoyu]

Tumu: adding the parameter -lm_4 sure fixed the problem. But only because I see nothing! Complete darkness, no walls - only thing I see is other players.

same effect.
Will it be better in GLQWCL? Because that's the only thing I want to play... ;-)

W2K, 5.04, G400, xgl200 glide wrapper.

Thanks, shogun. r_dynamic 0 works.

-lm_4 makes all but players and water black.

[Tumu]

Fury, strange, it works fine for me both in GLQuake and GLQW. The r_dynamic 0 works also for me, though then there will be no dynamic lights. :/

I'm using the OGL ICD, not TurboGL. You could also try the TurboGL to get a _nice_ speed boost. TurboGL should work without the -lm_4 parameter and r_dynamic 1 set.

TurboGL clears up any rainbow effect in Quake 1.

Actually, TurboGL fixes all my rainbow color effects in any Quake and Quake II engine. I just need one for Soldier of Fortune game .

I'm unfamiliar with the terms. What/where do I obtain the OGL ICD? I have the Turbo files but have not installed them.

2nd problem: Why doesn't QWCL work? It hangs at "checking sounds".

[Shoyu]

It would be really good if we can clear this up. If I can have dynamic lighting using ICD and not have rainbow textures it would be really great... so does anyone know why -lm_4 works only for tumu?

fury, OGL ICD is just the PowerDesk 5.52 you are using.

[Tumu]

Did some digging around for my previous post about the -lm_4 parameter and found it:

Also there has been a thread ( http://forum.matrox.com/mgaforum/For...ML/000025.html ) in the Matrox forums where I pointed this out and it seems that the workaround didn't work either with G400's.

Hmm, the only conclusion I may think of all this that the OGL ICD (or in very unlikely case, the hardware in G400 but not in G200) may be totally FUBARed concerning this issue.

Well, the next driver release might solve this problem if we're lucky..
