# Objective - Reduce compilation time ## Solution - Make `spirv` and `glsl` shader format support optional. They are not needed for Bevy shaders. - on my mac (where shaders are compiled to `msl`), this reduces the total build time by 2 to 5 seconds, improvement should be even better with less cores There is a big reduction in compile time for `naga`, and small improvements on `wgpu` and `bevy_render` This PR with optional shader formats enabled timings: <img width="1478" alt="current main" src="https://user-images.githubusercontent.com/8672791/234347032-cbd5c276-a9b0-49c3-b793-481677391c18.png"> This PR: <img width="1479" alt="this pr" src="https://user-images.githubusercontent.com/8672791/234347059-a67412a9-da8d-4356-91d8-7b0ae84ca100.png"> --- ## Migration Guide - If you want to use shaders in `spirv`, enable the `shader_format_spirv` feature - If you want to use shaders in `glsl`, enable the `shader_format_glsl` feature |
