 By default mesa uses llvmpipe. You can switch to OpenSWR by setting GALLIUM_DRIVER environment variable value to swr either globally or in a batch file. Mesa environment variables documentation is available [here](https://mesa3d.org/envvars.html). Build instructions, if you want to replicate my builds, are available [here](https://github.com/pal1000/mesa-dist-win/tree/master/buildscript).

-# Build script
-- Dead variables clean-up.
-- Load Visual Studio environment only when building LLVM with Ninja.
-- S3TC build: If both MSYS2 and standalone Mingw-W64 are installed let the user pick which to use.
-- S3TC MSYS2 build: prefer 64-bit MSYS2 over 32-bit if both installed.
-# Build script documentation
-- S3TC build with standalone Mingw-w64 is no longer deprecated. GCC 7.2 update finally took place.
-- You are now asked which flavor of Mingw-W64 to use when building S3TC if both MSYS2 and standalone are installed.
