While we have difftests, Use https://github.com/Rust-GPU/VulkanShaderExamples as benchmarks contains a lot of real-world shaders across multiple impls. We should use them as an additional difftest corpus. I am unsure if it is currently set up to render to a file to compare, but…

We don't have a benchmark suite. In https://github.com/Rust-GPU/VulkanShaderExamples, we have a bunch of shaders with the same logic written in multiple languages. Also, they have a way to benchmark built in. So all we need to do is automate running and reporting the benchmarks…
