What to change in the config.ini?

I have a pretty good comptuer I5-3570k (no over clock), 8 gig Ram, HD7970 and GSC2013 runs pretty well. I get about 60-100 FPS most of the time. However, I read a while back that performance can be improved through INI tweaks. Can someone link me to a good site on the the INI for GSC is setup or what lines I need to tweak?

Thanks, I made those tweaks and still the AA looks horrible with jaggies everywhere. I think it is an AMD issue.
