If you're per chance running on Linux/Intel/IvyBridge, it can be even faster than on Windows: Details: Windows 7 (latest Intel GPU drivers), Firefox 23 nightly Ubuntu 13.04 with custom Mesa git (Mesa 9.1 also works, but a bit slower), Firefox 23 nightly I had to set layers.acceleration.force-enabled variable to true in Firefox (in about:config) because it is blacklisted for some reason on Linux/Intel (probably some previously resolved bug). The browser Window was maximized in 1920x1080, and game view was not full-screened. Cpu is i5-3320M on Thinkpad X230 Windows: 40.5 FPS Linux: 43.6 FPS
