First I\\\'d like to thank Wouter for the high quality open-source 3D engine he has created and hope he keeps up the good work. Anyway, I downloaded Sauerbraten the other day and upon trying to init video, it threw an exception. So I found it would run with res at 640x480 and 256 colors. Wonderful. Turns out it would only use GDI to render. Now I\\\'m not a coder really, but I went tried some google queries for ATI SDL, etc. I found some coding forums with highly relevant information. It seems the problem is that certain drivers require that you request the number of alpha bits you need, should it be more than zero. So I added \\\"SDL_GL_SetAttribute( SDL_GL_ALPHA_SIZE,8)\\\" to to line 513 and now it works great.


PS After I started writing this I tried launching the standard binary and it works. Even after reinstalling I get no error. Bizarre.

Alright, I guess I can give you the rest of the details ;).
Open engine\main.cpp and search for this line:
SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
Below it add this line:
SDL_GL_SetAttribute( SDL_GL_ALPHA_SIZE,8)

My video card is a 9800 PRO with Catalyst 7.10 drivers.
