VulkanFX Optimized

⚠️ OUTDATED / DEPRECATED NOTIFICATION

🛑 ATTENTION: VulkanFX is no longer actively maintained for newer Minecraft versions.

With the release of Minecraft 26.2, the official Vulkan API backend has been natively integrated into major performance stacks. Therefore, this project has been merged into our main flagship pack:

Why switch to Renderium Optimized?

• Full Compatibility: Supports Minecraft 26.2 and the latest Fabric ecosystem perfectly.
• Native Vulkan: Uses the stable, built-in "Prefer Vulkan" rendering engine directly integrated into Sodium (no separate VulkanMod crashes).
• Up-to-Date Features: Features modern Quality of Life mods, EMF/ETF animations, and massive stability improvements without experimental desync issues.

If you still wish to use this legacy pack for older versions, the original description remains below:
