Ocuwheel

Ocuwheel is a compatibility mod for Create, Flywheel, and Iris/Oculus.

The problem

When Iris/Oculus shaderpacks are active, Flywheel can disable its GPU-instancing backend and fall back to CPU rendering. This can cause severe FPS drops around Create machines and large contraptions.

The fix

Ocuwheel keeps Flywheel’s GPU rendering backend active while Iris/Oculus shaders are running. It uses targeted compatibility Mixins and works automatically with shaderpacks without requiring per-pack patches.

FAQ

Why use Ocuwheel instead of Colorwheel?

Ocuwheel takes a direct, universal approach: it keeps Flywheels native GPU instancing backend active while Iris/Oculus shaders are running, without requiring shaderpack specific patches.
