Very funny cyan

.. your problems were with sli and those are fixed now. Granted the engine does perform worse then some other engines but its being looked into. Its just a huge riddle to the engine developers as the engine IS optimized quite well, it stresses the cpu far less then quake3 for example. For some strange reason the graphic drivers seem to dislike something the engine does but its hard to find out what. Part of the problem is that gfx drivers tend to be optimized for quake3 and that might give other engines problems.
HOWEVER 30fps on average with a 7600 IS TOTALY BAD and i have no idea what might cause it. You could take a look at this post:

I mention some system dependent variables at the end.. If i change two of them i get 10fps more on average compared to the default setting of those two variables, although someone with the same OS, gfx card needs to have them at the defaults or it will get slower. So it REALLY depends on the system if changing them will help. That why i do not mention any recommended settings for them, just try benchmarks and change them. But i doubt they will help to get 30fps to as high as 90 fps which i have at low settings.. and your card should get even more.
Did you look through the options in your gfx driver options to find settings that might affect opengl performance?
