Kerria

# Kerria ## Overview Kerria is a mod that optimizes texture animations. In vanilla Minecraft, texture animations are handled rather inefficiently. Each time a texture is updated, it is uploaded onto the atlas via the slow `glTexSubImage2D`, which involves CPU->GPU upload and may potentially incur a pipeline stall. This mod adds two optimizations to reduce the performance impact of animated textures: - **Texture Animation Cache**. Instead of performing an upload each time, we can cache non-interpolated animated textures once they are uploaded to the GPU. When the texture is subsequently needed, it is applied with a very fast GPU-to-GPU copy. - **Fast Texture Upload**. Optimize texture upload performance with persistently mapped buffers and pixel buffer objects. The optimizations can be configured through the Sodium/Embeddium video settings screen. ## FAQs **Is this compatible with Sodium/Embeddium's "Animate Only Visible Textures" option?** Yes. That option improves performance by skipping uploading animated textures that are invisible, while this mod actually speeds up the process of uploading animated textures.
