Well, the UT2003 demo was released for Linux. Unfortunately, it's kind of a bummer for multiple reasons.
a) cpu required is higher than my cpu, but I was going to give it a shot anyway
b) only works with nvidia cards + binary cruft driver right now because of needing GL_EXT_texture_compression_s3tc extension
c) said extension doesn't have support on tnt2 (the nvidia hardware I still have lying around)
Hmm… guess I'll drop by the office tomorrow and give it a try on one of my test box with the athlon 950 and a geforce3. The problem is that if I like it, I'll feel a need to get a new machine soon.
And this comes just after I had decided to wait until Christmas to upgrade hardware and that I was just going to get a new laptop then.
