I use the latest r600g driver from > xorg-edgers package repository for ubuntu Lucid. > > My most important OpenGL software is XBMC. It has three video renderers: > Software, ARB or GLSL. I notice (using the debug information of XBMC) that the > Software renderer is actually the fastest one, then ARB and finally GLSL. I > guess something is not well optimized in r600g with regard to video rendering. > This is especially true for 1080p video (sometime I get only 12-16fps using > OpenGL renderers while CPU usage is still only 50%. Software renderer could do > 24fps with 100% CPU.). > > FYI, I also have another similar desktop, but with ATI X1650 PRO card. On this > machine, using the r300g driver, the GLSL renderer is fastest (also similar to > ARB renderer) and is faster than the Software renderer. So, r300g is well > optimized with regard to video rendering. > > I file this bug hoping the developers could spare sometime optimize r600g for > video rendering. > > Thanks a lot I forgot to say, I have an AMD athlon 64 X2 dual-core CPU 4800+ (2.5GHz). -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
