Spark does some multi-threading though (I'm thinking physics\sound\networking\file-IO), which is probably what the r_mt-command is mostly for.

But you say to yourself, well, what could possibly be worth the wait? Good performance... few bugs... etc. That's what you're looking at. It's a matter of building from there

This release was completely worth it IMO - it made the game playable for me. In fact, not only does it play quite well most of the time, but I got ~80-100% fps increase. Seriously, it's freaking awesome, I can't wait for future patches.
I think I just had the best game of NS2 yet with this build just now but the game has started to crash often now. Well at least I can submit some useful crash data. :)
EDIT: Crashing could be due the AMD Rage drivers too but who knows.

The AMD rage drivers only seem to effect my open GL games, so RAGE (which makes it better) and half-life/ns (which it crashes). They only made opengl updates to the rage drivers, I believe NS2 uses D3D Level 9.
