    From what I undestand the big thing to do is to increase the VARSize 
from 32 to 64 in the ut2004.ini file. Here's what it says at 

      Speeding up AS-Mothership

Note: this tip may be specific to the Linux version and/or the OpenGL 
renderer. I was having major framerate issues with the AS-Mothership map 
with the Linux version of UT2K4 with my Athlon XP 1800+, 512M RAM, and 
an NVIDIA GeForceFX 5700 Ultra. No amount of in-game tweaking seemed to 
do any good. Ryan "icculus" Gordon (who did the Linux port for Epic) 
suggested opening up my UT2004.ini and changing VARSize=32 to VARSize=64 
to see if that would help. That made a dramatic change. VARSize controls 
how much static geometry in megabytes can be cached in AGP memory.

    Other than that it might be the limitations of your graphics card 
coming into play. I understand that the 5200's do overclock 20% fairly 
easily if you motivated in that way.
