    BTW, was the power profile default or high?

      Wow... that white text on cyan background is an all-time low readability record for Phoronix... what's up with the CGA colors?

        Yes, but if it has 60+ FPS for the applications you need competing (optimizing remaining "bottlenecks") is kind of pointless. That's competing enaugh for me.

        It would be definitely very good if it was supported for more video codecs, but what CPU does your HTPC have and what quality of videos do you want to play?

        Except for Playing Portal 2 in wine or all of the games in the humble bundles.

            Well,VDPAU via 3d shaders seems to work, just VDPAU via UVD isn't released:

            /usr/lib64/vdpau/libvdpau_r600.so.1

              Taxi but the decoding runs on the cpu only mpeg2/1 is currently hardware accelerated.

                Yes, it clearly says it's using ffmpeg's h.264 codec implementation, only the display part is done by the vdpau implementation, and that part works just as well with xvideo.

                  The last time I checked, it only supported mpeg 1 and 2.

                    it seems the biggest bottleneck roght now it is on the lack of shader packetizer and threading but the fixed functions seem pretty competitive right now wtih catalyst

                      I wouldn't call it "remaining bottlenecks" as long as the binary blob is still 2-40 times faster.

                      My HTPC has an AMD X2 4050e with an onboard AMD HD 3???. It is capable of playing Full-HD videos with the binary blob. However I'm currently using a NVidia GTX430, as XBMC or the Catalyst driver has/had problems with vba (got display errors with some hd-videos) and suspend-to-ram. I'm pretty much done with AMD, my next system will be an Intel Atom with a Nvidia chipset. Nvidia is just the only problem-free solution on Linux.
