The goal of this project is to provide tools for mod developers so they no longer have to worry about performance, or limitations of Minecraft's archaic rendering engine. That said, this is primarily an outlet for me to have fun with graphics programming.


Flywheel provides an alternate, unified path for entity and tile entity rendering that takes advantage of GPU instancing. In doing so, Flywheel gives the developer the flexibility to define their own vertex and instance formats, and write custom shaders to ingest that data.


To accomodate the developer and leave more in the hands of the engine, Flywheel provides a custom shader loading and templating system to hide the details of the CPU/GPU interface. This system is a work in progress. There will be breaking changes, and I make no guarantees of backwards compatibility.


Flywheel uses its technology to optimize vanilla tile entity rendering. Currently, this is only implemented for chests and bells, but eventually Flywheel will accelerate all tile entity and all entity rendering. This will be released on a rolling basis, with updates coming as individual optimizations are made.


  • More vanilla performance improvements
  • Different renderers for differently aged hardware

A Note on Optifine

Flywheel is mostly compatible with Optifine. If you use shaders, however, Flywheel's optimizations get disabled.
