    that "benchmark" is of a pre-production video driver vs stable video driver, probably with very early xvba video outputs from mplayer vs more mature vdpau video outputs from mplayer

    and the two cards used were not even close in performance levels.

    bottom line.... trying to draw any conclusions from that "benchmark" either way would be entirely premature.

      Huh? Where are they?

        I think ethana2 is referring to Gwenole's benchmarks linked off this report :

          Thanks a lot bridgman, but indeed what results can someone accept when the benchamrks are between so different in value hardware?

            I believe the rationale is that both low end and high end GPUs have the same video decode block, so within a GPU generation the model shouldn't make that much difference. I think that is generally correct. The issue with these specific benchmarks, flagged both by Gwenole and others, is that the NVidia chip used had an older decode block which did not fully accelerate VC-1.

              Finally, with 9.9 Stepmania doesn't crash anymore.

              With 9.8 and older versions, the whole X server crashed randomnly when playing Stepmania and the system freezes.

                VC1 is fast enough with NV, i just did not think that so many Bluray Discs would use it, but it seems it even more common than H264. The picture quality seems to be even a bit better (but could be the input data too). The main problems are a/v sync problems with mplayer (the only player i could directly play m2ts with accelleration).

                  I can't get fglrx 9.9 running at all anymore (and somehow not even the older ones that used to work), I'm stuck with radeonhd.
                  Install works fine, but no matter what I do X hangs on start-up.
                  First as usual X crashed when loading amdxmm.so (as with every version of the driver) so I renamed the file, but now hanging on start-up instead of crash.

                  Nothing I can see in the log file

                    True, performance is the same on RS780G and M98, among some others. Since the UVD2 is used, that won't change anything. However, if you want to implement video decoding through the GPU/shaders, that will obviously make a difference.

                    Actually, I am now only testing on RS780 and I did not notice any difference. CPU is still as low as with M98 and my ears are happier...

                    BTW, the NVIDIA module in an AMD riser card somehow made it run at half speed only. ;-)
