Intel's Mesa GLSL Shader Cache Is Speeding Up Game Load Times

Serious Sam 3: BFE with OpenGL sees some nice load time savings with using the Intel GLSL shader cache.

As well as with the higher quality settings.

As you can see from this quick round of testing, the Intel GLSL shader cache does help in speeding up load times with not having to recompile GLSL shaders when cached. But the shader-heavy games are those that tend to not run fast with HD/UHD Graphics right now anyways and even Iris Graphics not handling too many Linux OpenGL games gracefully. Nevertheless, it's nice to see this technology in place and you can try it with Mesa Git by setting the environment variable until it's flipped on by default.
