[Mesa-dev] Time to merge threaded GL dispatch? (aka glthread)

[Ernst Sjöstrand]

I benchmarked Total War: Attila and CS:GO quickly yesterday, both ran fine
but none of them seemed to gain any performance. Maybe lost a little.
I saw that Tomb Raider only had ~130% cpu usage on my system, perhaps
that's a candidate even though it's a Feral title? It's 32-bit though and I
couldn't bother to cross compile.

FYI I think glmark2 is a bit buggy: https://bugs.launchpad.net/glmark2
Tough it does run fine for me without threading right now...

Regards
//Ernst
