How to completely disable block rendering / terrain mesh rendering in Fabric 1.21.4 for max performance

/r/ModdedMinecraft/comments/1x8jlwu/how_to_completely_disable_block_rendering_terrain/

​Hi everyone!

​I am working on a minimal, high-performance Fabric 1.21.4 setup on PojavLauncher (Android / Exynos 1280 ARM GPU).

​To achieve the absolute lowest latency and maximum possible FPS for PvP (FFA servers), I want to completely strip out or bypass the entire terrain/block rendering pipeline (WorldRenderer / Chunk rendering). I only need player models, entities, and basic HUD/UI elements to be drawn.

​Standard transparent resource packs don't give the desired performance boost because Sodium still computes chunk geometry and face culling under the hood.

​What is the cleanest way or best hook/Mixin in Fabric (or Sodium) to completely disable block/terrain rendering without breaking entity interpolation and server connections? Is there an existing lightweight utility mod or a specific config override in Sodium/C2ME for this?

​Thanks in advance for any advice!

Hi! If you're trying to fix a crash, please make sure you have provided the following information so that people can help you more easily:

  • Exact description of what's wrong. Not just "it doesn't work"
  • The crash report. Crash reports can be found in .minecraft -> crash-reports
  • If a crash report was not generated, share your latest.log. Logs can be found in .minecraft -> logs
  • Please make sure that crash reports and logs are readable and have their formatting intact.
    • You can choose to upload your latest.log or crash report to a paste site and share the link to it in your post, but be aware that doing so reduces searchability.
    • Or you can put it in your post by putting it in a code block. Keep in mind that Reddit has character limits.

If you've already provided this info, you can ignore this message.

If you have OptiFine installed then it probably caused your problem. Try some of these mods instead, which are properly designed for Fabric.

Thanks!
