Details

The PhobosLab HTML5 benchmark is extremely slow in FF8 and above when hardware acceleration is enabled. It seems like it's probably performing some canvas operation that is slow in hardware. If you turn off hardware acceleration in settings, it runs really fast.

Here are some timings (the frame time value shown in the top left, next to the FPS):
Firefox 8 (hardware acceleration on): 60-75ms
Firefox 8 (hardware acceleration off): 6-11ms
Aurora 10.0a2 2011-12-11 (hardware acceleration on): 60-70ms
Aurora 10.0a2 2011-12-11 (hardware acceleration off): 4-6ms
FF3.6: 15-28ms
Chrome 15: 1-4ms


Here's the Graphics section of my about:support. None of the graphics prefs have been changed in this profile.

Yes, seems like it. Chrome's in the 10-20ms range on my machine, latest FF nightly is 2-5ms.
