Phoronix: Mir-On-X11, Latency Drops & Other Changes Coming To Mir 0.15

While Mir 0.14 just recently appeared in Ubuntu 15.10's archive followed by Ubuntu 15.04, Mir 0.15 is already under heavy development...

I would like to see the following benchmarks:

• X vs Wayland vs Mir
• X vs Xwayland vs Xmir
• Wayland vs Xwayland vs X
• Mir vs Xmir vs X

Relative motion events aren't necessary for first-person shooters at all. XCB doesn't emit relative motion details. You get the relative change yourself based on where the mouse was the last time you got input. It would be propaganda to say that because of this Mir only now supports first-person shooters.

Pretty sure they are going have absolute mouse position events too. Its just those games don't need to do the hacky-way themselves anymore.

As to performance: W and Mir were created not to yield more OpenGL FPS, but to give better (smoother, more predictable, not faster) frame rates than X11.

Of course there are many more reasons why Mir and W are to succeed X11.

WIN32 doesn't emit relative motion events either. It isn't the "hacky" way. It's the only way. This new addition is just a nice little dev-helper for Mir, which is nice to see. Most games don't directly interface with the display server or window manager though, so most developers use SDL or some other API that has those "hacky" methods already built in. OR, even better; use direct input handling.

P.S.
Mir isn't "going to have" absolute motion events; it already does, or it would be damn-near useless.
