You're not giving anyone much to go on there - graphics card? driver version? OS? CPU? available memory? GZDoom version? Mother's maiden name?...

How about some information I could actually use (like startup log or eventual error messages.) Obviously there is something wrong on your system and I need at least a clue.

First clue:when changing graphic mode disables and enables gzdoom and only stays in software mode i don't know why well now

Could you post the output generated by starting 'gzdoom +logfile log'?

This is a simple suggestion. Make sure you have installed the CATALYST drivers correctly.. this means uninstalling previous versions before installing newer versions. (This is essentially true for all video cards in general.)

The latest drivers should work just fine.. if you are using archic drivers (or installed it incorrectly), you shouldn't expect it to work in the first place.

Ok, since I get no useful information here let's get this out of the way.

And here's the reason:

R_OPENGL: Desktop not in 32 bit mode!
Try to switch your desktop from 16 bit to 32 bit and it should work. I have no idea whether this is really necessary but it was in the startup code I used for GZDoom before I got it.

(I think I remove that line from the code though if it works on my system.)

Could you change code to support opengl 24 bit?

Post by **Graf Zahl** » Wed Dec 07, 2005 22:13

No. Modern graphics cards don't support 24 bit anyway. They only offer 16 and 32 bit and I don't know a single older card that can do hardware rendering in a 24 bit mode. Memory access is just too inefficient.

Deathlike2 · Post by **Deathlike2** » Wed Dec 07, 2005 23:54

Is there any effect that requires 32-bit? Just curious...

24-bit isn't really supported by the ATI Radeon 9600 anyways (like any modern graphics card).. so asking for the feature anyhow would be rather pointless.
