Details
Firefox's performance is much worse than Chrome on the following page extracted from the webgl2 conformance test suite: http://people.mozilla.org/~jmuizelaar/js/gc-test/WebGL%20Texture%20Shadow%20Conformance%20Tests.html Chrome Canary should be used and must be run with --enable-unsafe-es3-apis to enable WebGL2 The page will output lines like: compare took: 3260.2350000000006 Chrome gets: compare took: 569.9849999999997 This comes from the computeTextureCompareDiff2D where the majority of the time is being spent. computeTextureCompareDiff2D is creating lots of temporaries. I tried reducing the page but didn't have much success.
