Potassium

Update to 26.2

Potassium 1.6.1 now supports Minecraft 26.2 and moved all rendering to Mojang's Blaze3D API, along with Vulkan support.

Blaze3D-Safe Rendering

• Added conservative Blaze3D backend detection logging.
• Added shader-cache backend signature validation for safer renderer changes.
• Keeps existing shader-pack safety gates and crash protections.

Note

Currently Unavailable features:

All super-resolution algorithms (Potassium Spatial, FSR1, FSR2, FSR3, SGSR1, SGSR2, DLSS, XeSS) — disabled on Vulkan (no render graph API migration yet) and on Apple Silicon (water/transparency depth issues) Native DLSS/XeSS/FSR3 frame gen — only functional if the native vendor SDK bridge reports support
