           Summary: Vsync always on
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: sa at whiz.se


With kernel 2.6.35, there doesn't seem to be a way to turn off vsync/vblank. 

E.g. "vblank_mode=0 glxgears" has no effect.

This seems to be the same for both r300c and r300g.
