           Summary: WebGL in Firefox is very slow (pegs the cpu)
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: sa@whiz.se


WebGL in Firefox (4.0b1) is very slow on r300g, it seems to be using an
excessive amount of CPU, this is not the case in Chrome, where things seem to
be working very well. 

I'm not really sure if this is a bug in the driver, or in Firefox, but on i965
performance seems to be the same in both browsers.

This problem is very noticeable in demos which measure framerate, such as:
http://cs.helsinki.fi/u/ilmarihe/demo/demo.html
http://cs.helsinki.fi/u/ilmarihe/demo2/paint.html

Another good test is an interactive demo like the teapot, where lag is
noticable:

WebGL requires support for pbuffers (for both Firefox and Chrome) so Xserver
1.9.0 is required. For more general tips on getting webgl running see:

Using git master (from yesterday?) this is no longer a problem!
