for OGL i thought increases are seen in all drivers 28.90+
You are right, but Rivatuner 11.1 has a patch that gives you a performance boost for OGL that gives you the better performance using det 30.30 than previous versions.
There are beginning to appear some suggested settings on the guru3d forums mostly for UT engine.
Again I encourage imtim83 to visit the guru3d forums www.guru3d.com
, who better to explain rivatuner settings than Unwinder himself.
