Maybe cus it's underclocked. Binary driver increases GPU clock when in 3d, nouveau doesn't (yet), or thats what I read. Thats why 3d is slow with nouveau. Plus some other stuff that might be missing and is SW emulated by mesa I guess. On integrated gf 6300 it gives ~0ish FPS in regnum, nvidia driver gives ~20 (both in fixed pipeline). gf9600gt was ~15-20ish in fixed pipeline, 10ish in SM2 with nouveau and ~80ish (in SM4) with nvidia driver. 1280x1024 resolution.
GF9600gt is actually slower with nouveau than gf6300 with nvidia driver!!!
Nouveau is just not ready for all the 3d stuff and I don't think it will ever be close to nvidia driver. The only use for nouveau I see is after nvidia drops support for those GPUs in their driver, then one can be glad nouveau exists ^^.

*the numbers are what i remember from some time ago. I can't test that with those cards on amun and with newer nouveau release because my 2nd motherboard is fried (so it was f*ked PSU after all

). And since buying new PSU and another MB is waste for such old PC, I am stuck with laptop and intel x3100 which gives like 5-10 in fixed pipeline if lucky (almost the nouveau performance, see how nouveau is doomed?

). I rememeber when it gave ~20-30 in RO before the UI update, me wants that back please???!!!!
