I have an old crappy ATI 128 Pro with XP SP2... But I can run most GL stuff just fine.

If the card is too old it is possible that it doesn't support a stencil buffer. I am using that one for several rendering tricks so it won't really work without it...

It's just too bad that you can't get any information about implementation of such features anywhere.

The specific cause for the reported bug has been fixed.

Nightmare, when I upload a new version this evening please check it out and tell whether it works or not.

The good news: the problem I experienced on my laptop with almost everything being completely black has been fixed - even with depth fog turned on

!

The bad news: I still can't switch to OpenGL mode on my desktop

What does it say now?

"ZGL: OPENGL DRIVER NOT ACCELERATED! FALLING BACK TO SOFTWARE RENDERER."

Well, then you are out of luck. This means that your card (or driver) doesn't support something I need, most likely the stencil buffer. And to be honest, considering that your driver neither supports an extension that has been around for some time now and neither manages to get an accelerated rendering context I have to say that something is very wrong there...

Strange that GL Quake works absolutely fine...

Please start the game with gzdoom -set developer 1 +log logfile and post the log file's contents. Then I can at least see whether your driver is up to date or not. This is clearly something that should not happen.

That didn't do anything, did you mean +logfile log? If so, the resulting file doesn't seem to mention driver versions.

However, I can tell you that I'm using Catalyst 5.8, which was released on the 17th August 2005. If you like, I can try one or more older versios of the driver, though it's probably worth finding out if anyone is using Catalyst 5.8 with no problems in GZDoom.

Since the GL driver didn't initialize the info I needed is not in there.
Can you do the same with gl_vid_allowsoftware set to 1?

THat doesn't tell me much. I think I'll add some code into the next version that outputs more information during the startup process. I'd really like to know what is happening here.

Me too

. GZDoom runs fine on my laptop now, but I really miss the huge resolutions my desktop allows

Post by **Graf Zahl** » Sat Sep 03, 2005 13:37

Out of curiosity, have you tried lower resolutions. Not that that should make a difference but who knows?

NiGHTMARE · Post by **NiGHTMARE** » Sat Sep 03, 2005 13:47

I have - everything from 320x200 to 2048x1536. I even tried it in window rather than fullscreen.
