This issue may be related to the graphics regression at bug 1247585.

I am getting rock solid 60 FPS on my Macbook Pro in both Firefox 44 and Chrome 48.0.2564.109 (64-bit). Just reporting per Jukka suggestion as this may point to Windows only/ANGLE problem. This is a beefy machine with both the Iris Pro and nVidia secondary GPU FWIW.

Tested. I am averaging 24FPS and never hits 30FPS+ on my MacBook Pro 13" using Firefox 44.0.1.

If you set the webgl.enable-prototype-webgl2 preference to false in about:config do things improve?

It's value is already set to false.

Ironically if I do set the preference to 'true' — the assets don't load.

Oh sorry, I didn't realize you were using FF44. Is there a version that you see a performance regression compared to?

No. However Comment 2 from Andre is likely from very similar hardware and also on using Stable 44.

[Martin Best (:mbest)]

Yep.

Comment 10

[Milan Sreckovic [:milan] (needinfo for best results)]

Given comment 9 and comment 2, should this be tagged as "with E10S enabled"?

Comment 11

[Milan Sreckovic [:milan] (needinfo for best results)]

I get 60fps Windows 7 SP1, 32-bit Firefox 44.  Quadro 600.
