Didn't have these issues using 2.5.1:9998 or anything lower than that.
Edit: After digging much deeper I have more info, I didn't know my hardware.
Windows XP SP 3
Nvidia 9800 GT
4GB Ram
AMD Athlon Dual Core 2.7GHZ
and I can't get the command prompt thing to work. Keeps annoying me about -basedir or some crap. Everlasting windows problems...
Edit: Forgot. yes I do know about r_fog r_water r_showtris and all the rest of the stuff. I tried the r_water and the same thing keeps happening. Also tried redownloading...
Tried it on suse too. works fine there I'll just use that. But thats still an issue maybe for some people.
