No good for Half-Life, I'm afraid :-( I've run `patch < savagestate.diff' in the
./src/mesa/drivers/dri/savage dir, recompiled the Mesa driver, copied it into
/usr/X11R6/lib/modules/dri and restarted X. No change in Half-Life. Boohooo ;-(

O...kay :-) Think I get the idea. Well, in Half-Life, even when I get closer to
some of those walls or anything, the texture remains shredded. Also, when I
just walk straight forward, sometimes the correct textures turn into the "bad"
ones when I get close to them. They just randomly rotate from good to bad and
vice versa, however there is usually some part of the level which looks good
all the time.

Take your time, I'm not hasting anyone. Just wanna know where the problem lies.

If you need further testing, just tell me >:-]

Good luck out there,
