Now for 2d desktop acceleration using xrender this part is not using platform agnostic code, it is using linux/x11 specific code which what they said they would be optimising. So basically what I'm saying is don't get your hopes up...
I just want to report that with the 177.70 drivers my performance in UT2k4 is now excellent. I believe there had to be a fix in the beta drivers. The game now runs flawlessly. Of course the desktop performance is also vastly improved with the new 2D performance enhancements. The beta 177.70 drivers are simply awesome as far as I can tell.
