    When it comes to the OpenCL performance for the Radeon R9 270X, the performance came up short of the Radeon HD 7950 but surprisingly the NVIDIA GeForce Fermi/Kepler performance was awful with the NVIDIA 331.13 Linux graphics driver for the LuxMark workload
    not really.

      2D Open source works well under Fedora 19

      I received my MSI R9 270X yesterday and played it with open source driver in Fedora 19.

      Without any hacking or additional kernel parameters, it turns out to be very well, at least for average desktop 2D usage.

      DPM works so it's power efficient, only adding roughly 5W to my total power consumption.
      VDPAU works and it seems to decode H264 well and no crashes, at least for a 10 mins 1080P clip.
      Desktop effects works in GNOME Shell. Not sure about KDE/Kwin though.

      However, I do spot some rendering corruption on Control Panel toolbar. Not sure why it's there because other GTK3 applications(Nautilus, Rhythmbox, Document) doesn't show this problem.

        I'm curious as to why the 7850 is... lacking in a lot of those tests, especially in-comparison to a 7950 and R9 270X...

        I just figured "all" newer cards under Linux were generally lower-performing because of drivers currently, but that doesn't seem to be the case.
