Commen= t # 37 on bug 97879<= /a> from Micael Bergeron 
The number of shaders is quite astonishing.

Could using the r600 shader compiler LLVM (--enable-r600-llvm-compiler) fix
this?

As for the future, I think a persistent shader cache is probably the quicke=
st
way to patch this so the game is enjoyable. After that, a more subtle appro=
ach
could be used:

> Possible solution 2:
> - convert shaders from TGSI to ISA in Mesa (we can use the LLVM assemb=
ler,
> but we need good register allocation for TGSI)
> - LLVM compilation should follow and be fully asynchronous

Rocket League is a really popular game, which I think the Linux community
should embrace. Thank you guys for making this work.
