           Summary: The new MESA degrades performance on RS690M and x1270
                    graphs chip.
           Product: Mesa
           Version: 7.5
          Platform: All
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/DRI/R600
        AssignedTo: dri-devel@lists.sourceforge.net
        ReportedBy: de.techno@gmail.com


I don't exactly remember but I think the 6th version of mesa used to draw ~500
FPS in glxgears. With mesa 7.5, it's ~350 and 7.7 it has dropped to less than
200. Same for the latest development version of mesa (i'm using Gentoo and the
latest development version is the one provided by the live ebuilds in the x11
overlay).

The direct render is in general very slow on this chip; 500 FPS is very less
considering the performance of this chip.
