This is a thread for posting benchmarks if you have any.
Mesa repo that contains the compiler: https://github.com/daniel-schuermann/mesa
* Testing instructions.
* Bug reporting.
Compiler is enabled by default. To disable it and use regular amdgpu/llvm compiler with the same Mesa build, set the environment variable:
RADV_PERFTEST=llvmSee:

amdgpu/llvm
aco:
Not bad! It produced around +3 fps for me on average (+3.6% improvement) in the busy street in Novigrad.
GPU: Sapphire Pulse Vega 56
Resolution: 1920x1200.
CPU: AMD Ryzen 7 2700X.
I had to use llvm 8.0.1 though, since 9.0 snapshot currently causes a GPU hang. So would be interesting to compare with 9.0 once it will be fixed.

Plus, I'm not sure how recent Blender is in Debian testing now, due to freeze (it will end soon though).

Mesa does it by the version, so I'd say no need. New build will have a different version.

I'm having troubles compiling. What flag should I pass to -dri-drivers?? seems that part is failing? just swrast is ok??

I used my usual Mesa build script (except using the relevant git repo for the source instead of upstream one). It built fine without setting any dri-drivers.
The relevant part ($arch_dir is my variable):
-Ddri-drivers= \-Ddri-drivers-path="${arch_dir["64"]}" \
"-Dvulkan-drivers=amd" \

You can see how Debian builds stock Mesa here: https://buildd.debian.org/status/fetch.php?pkg=mesa&arch=amd64&ver=19.1.1-1&stamp=1561995279&raw=0
I used that as a starting point for my script.
Since it's just for testing purposes, you can skip everything but radv altogether. Don't replace your regular Mesa with it. Just run the game on demand with the built one placed in dedicated location. That's what I do.
