https://bugs.freedesktop.org/show_bug.cgi?id=29067 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@xxxxxxxxxxxxxxxxxxxxx ReportedBy: sa@xxxxxxx 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: https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/demos/google/shiny-teapot/index.html WebGL requires support for pbuffers (for both Firefox and Chrome) so Xserver 1.9.0 is required.
