using Glide and not miniGL (I'm no expert, but there is no opengl32.dll in the Quake folder).

You're using OpenGL by that point, GLQuake will attempt to use the system ICD (which would be 3dfxogl.dll on Banshee) if there is no minigl provided. and since it's a third-party driver, that ICD's probably some compiled 'mesafx' thing that might have problems

There's also sometimes problems with GLQuake defaulting to 640x400 fullscreen which can cause problems with some drivers so you should specify a res at least. Also make sure it's 16-bit color

Thank you for the feedback. So if I understood you well I should try different versions of the 3dfxogl.dll and see how it goes?

I am still not sure to understand what is the difference between running the game windowed and full-screen. Are there different 3D API involved?

Also I'll try out the Darkplaces engine, maybe that will solve my problem.

FInally managed to find a solution thanks to a redditor... After forcing the color depth with "-bpp 32" AND enabling the miniGL driver the game now works fine @ 1024x768.

I am super happy.

Btw on my setup I am getting around 30 fps @1024x768 and 40 fps @800x600.
