[Mesa-dev] Intel HD4000 Epic Citadel (Unreal Engine WebGL demo) performance regression and some comparisons with Windows

[Vedran Rodic]

As Eric suggested in the bug, setting
layers.acceleration.force-enabled (current Mesa git + patch series to
fix Y tiling) frame-rate goes to 43.7 FPS, compared to 40.5 FPS in
Windows 7 (latest Intel drivers).

Congratulations, we're faster than Windows (assuming that Windows
aren't blacklisted too) :)
