SwiftShader is now open source: https://swiftshader.googlesource.com/SwiftShader We should be able to package it up and distribute it in a similar way to OpenH264 and the other CDM plugins so that we don't pay the cost of distributing it to most people. I don't know how the performance compares to WARP, but having SwiftShader available as an alternative may be very helpful if we run into unsolvable correctness, performance or security issues with WARP.

Sounds like we want to examine the Windows XP success rates for WebGL first.
44% of our WebGL failures are on Windows XP. This percentage will go up when we ship DXGI1.1 WARP which will take care of a lot of our Windows 7 failures.
And for a different perspective, WebGL fails to work for 62% of our XP users. Here's a break down of the useful CPU features for target audience of nowebgl-xp: SSE2 - 99.30% SSSE3 - 58.07% SSE4_1 - 12.74%

Core count: [(1, '35.41%'), (2, '63.09%'), (3, '0.20%'), (4, '1.30%')] CPU count: [(1, '22.47%'), (2, '75.43%'), (3, '0.20%'), (4, '1.91%')]
