Polydium

Miscellaneous client-side optimization mod built by Polyfrost. On average, adding Polydium alongside the OneClient modpack improves average FPS by 40%.

The magic of this mod is how it works with other mods. Polydium works the best alongside Sodium, using its infrastructure to improve performance in mods such as 3D Skin Layers.

Vulkan backend on 1.21.11-26.1.2

This mod brings Vulkan to 1.21.11-26.1.2 by backporting Mojang's Vulkan implementation to these older versions. Any mod which supports Vulkan on MC 26.2+ supports Polydium's Vulkan backend (including Sodium).

By pairing this alongside Polydium's own Vulkan optimizations, you can expect better FPS than VulkanMod whilst maintaining compatibility with every mod in your mods folder.

Other notable features

• Batched particle rendering (works ALONGSIDE Particle Core), writing whole particle layers straight into the vertex buffer
• Particle section culling, skipping particles in chunk sections Sodium has already culled
• GUI item baking, redrawing animated items only when their animation actually moves
• Cached block entity lighting, entity cull boxes, and entity shadow lookups
• Faster startup and resource reloads through shader, pipeline, and resource pack caching
• Optimizations for the new Vulkan backend
• F3 debug screen caching, refreshing entries on an interval instead of every frame
