Lowering OpenGL level in Sauerbraten?

[Gentooer]

According to http://www.x.org/wiki/RadeonProgram, Sauerbraten should be playable on my r500 with the radeon driver. I've tried running it with the "-f0" option, but it still says that it's using OGL 1.5 (I think radeon only supports 1.3). It runs very, very slow and is obviously using software rendering. Am I missing some option to lower the graphics even more? I can't even get to the in-game options.

Look at the console output. This is what I get with my R500 card:

Note that the R500 driver, while is supporting only OpenGL 1.3 is very close to 1.5 (missing only 3 extension that are either not used (fog) or workarounded in sauerbraten (occlusion query): see http://dri.freedesktop.org/wiki/R300ToDo)

I am having about 10-40 fps.

Also make sure to use at least sauerbraten 2008-06-20 (the latest as of now).

Ok so I guess it is a bug with my drivers because I have the same output as you then a 1000's of errors:

I'll see what the radeon devs say.

EDIT: Just the found the bug report; it's a known bug in current mesa: http://bugs.freedesktop.org/show_bug.cgi?id=17929

There is a patch to test in the bug linked.

This starts Sauerbraten as a dedicatated server. The default is a non-dedicated server with only a single client in graphical mode. Dedicated servers run in the shell only (no graphics), with increased priority yet use very little cpu time and memory, so you can run one in the background, or at the same time with a client if you want to host a game (which is usually better than using a listen server). Servers use the ports 28785 (UDP) and 28786 (UDP).
