Threaded OpenGL Dispatch
The long-standing patches for implementing threaded OpenGL dispatch have landed in Mesa 17.1-devel Git.
Marek Olsak and then Timothy Arceri took to getting OpenGL threaded dispatch across the finish line and they've managed to do so over night in Mesa Git.
The code for OpenGL threaded GL dispatch is now finally in Mesa-git, after multiple developers attempts to fix it up. This should improve performance in multiple games for users of the open source Mesa drivers.
