Bug Description

I own an iMac with the new M3 chip, and I've noticed significant differences in FPS between Sodium and vanilla Minecraft or with VulkanMod. With Vanilla or VulkanMod, I can achieve 100+ FPS in the same area, whereas with Sodium, I only get around 30-70 FPS. Additionally, chunks load much slower, and the fans start spinning rapidly. When I touch the iMac, it feels very hot. However, this isn't the case with Vanilla or VulkanMod.

Reproduction Steps

Install Fabric and Sodium on a Mac with Apple Silicon (M1, M2, M3)

Crash Report

I am unable to generate one. I've tried using Fn+F3+C, but nothing happens.

The issue tracker is only intended for bug reports, not help requests. Please ask on the community Discord server.

But please keep in mind that Apple's ARM processors do not meet the minimum hardware requirements due to lacking OpenGL support, and that it is unlikely anyone can fix the issue.
