# Objective - Fix sprite rendering performance regression since retained render world changes - The retained render world changes moved `ExtractedSprites` from using the highly-optimised `EntityHasher` with an `Entity` to using `FixedHasher` with `(Entity, MainEntity)`. This was enough to regress framerate in bevymark by 25%. ## Solution - Move the render world entity into a member of `ExtractedSprite` and change `ExtractedSprites` to use `MainEntityHashMap` for its storage - Disable sprite picking in bevymark ## Testing M4 Max. `bevymark --waves 100 --per-wave 1000 --benchmark`. main in yellow vs PR in red: <img width="590" alt="Screenshot 2025-01-01 at 16 36 22" src="https://github.com/user-attachments/assets/1e4ed6ec-3811-4abf-8b30-336153737f89" /> 20.2% median frame time reduction. <img width="594" alt="Screenshot 2025-01-01 at 16 38 37" src="https://github.com/user-attachments/assets/157c2022-cda6-4cf2-bc63-d0bc40528cf0" /> 49.7% median extract_sprites execution time reduction.
