This is my first post to this forum. Every second Google result in my journey went here. Great work!

I currently experience these graphical glitches with my Voodoo 3 3000 setup, I came to rebuilt after 25 years of storage:

The attachment glitchquake3voodoo33000.jpg is no longer available

Some textures flicker and I can even see bots through walls. See it in motion: https://www.youtube.com/watch?v=fIhJvGOkvpE

This does only occur with the Quake 3 Arena Demo I have downloaded. Other games like Unreal, Unreal Tournament, Motocross Madness and 3dMark99 rune fine with no such errors. I even got a decent 3dMark score.

The card runs hot and I have now attached a fan. What could be the issue? Is it my driver version (voodoo3-10300.zip) or anything else? Could the card be damaged? Does this early version of Q3A miss Glide support? Where should I start?

From my recollection I had some issues with my Voodoo. I remember graphical glitches when playing GTA3 when it released. I moved to a different graphics card later on. In the mean time I used my Voodoo in a dedicated Linux HTPC as a TV out with no problems. It has been safely stored for the past 15 years.

I have installed the following drivers and game versions with sha1sums:

I'd try slightly newer drivers like 1.04.00 or 1.05.00 (but not 1.07.00 as I feel that's regressed V3 some)

Q3A never had a glide mode, the only 3dfx things it does is send a special color ramp to the card and prevent trilinear filtering. The rest is up to the OpenGL ICD

r_primitives is a cvar to also play with for this as that deals with how the renderer draws polygons. 2 is the fastest path, 1 is a slightly slower fallback, and 3 is a slow method that won't get picked. 0 tries to pick 2 if it finds a CVA extension (a root cause of benchmark skew when it doesn't)

I installed

and it is working perfect now! No graphical glitches anymore.

Thank you
