The number of shaders is quite astonishing.

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

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

> - 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.
