# Objective Speed up the render phase for rendering. ## Solution - Follow up #6988 and make the internals of atomic IDs `NonZeroU32`. This niches the `Option`s of the IDs in draw state, which reduces the size and branching behavior when evaluating for equality. - Require `&RenderDevice` to get the device's `Limits` when initializing a `TrackedRenderPass` to preallocate the bind groups and vertex buffer state in `DrawState`, this removes the branch on needing to resize those `Vec`s. ## Performance This produces a similar speed up akin to that of #6885. This shows an approximate 6% speed up in `main_opaque_pass_3d` on `many_foxes` (408.79 us -> 388us). This should be orthogonal to the gains seen there. ![image](https://user-images.githubusercontent.com/3137680/209906239-e430f026-63c2-4b95-957e-a2045b810d79.png) --- ## Changelog Added: `RenderContext::begin_tracked_render_pass`. Changed: `TrackedRenderPass` now requires a `&RenderDevice` on construction. Removed: `bevy_render::render_phase::DrawState`. It was not usable in any form outside of `bevy_render`. ## Migration Guide TODO |
