Well, it's unreal engine 3, so it doesn't surprise me that it compiles shaders
on demand. All UE3 games are affected in the same way.

Possible solution 1:
- persistent shader cache on the disk

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

Comments welcome.
