The Vulkan Priority

⚡ PURE PERFORMANCE

The Ultimate Fabric Optimization Modpack

“No gimmicks. Just performance.”

This modpack is a hand-picked collection of the best optimization mods available for Fabric 1.21.11. Every mod has been carefully selected, configured, and tested to work together harmoniously.

What makes this pack special?

Unlike other “optimization” packs that throw random mods together, this pack focuses on complementary optimizations that don’t conflict or overlap. Each mod targets a specific performance bottleneck:

⚠️ Important Notes:

This pack is pure optimization, no content mods, no new biomes, no gameplay changes

VulkanMod requires a GPU that supports Vulkan (most GPUs from 2016+ do)

Shader mods (Iris/Optifine) are NOT compatible with VulkanMod

The pack includes Fabric API and required libraries for maximum compatibility

📌 Requirements:

Minecraft: 1.21.11

Mod Loader: Fabric

Java: 21

GPU: Vulkan-compatible (NVIDIA Kepler+/AMD GCN+/Intel HD 500+)

Perfect for:

✅ Low-end PCs / Laptops

✅ Servers needing better TPS

✅ Players who prefer vanilla gameplay but want better performance

✅ Base for adding your own content mods

Not recommended for:

❌ Players who want shaders (use Sodium/Iris instead)

❌ GPUs without Vulkan support

❌ Modpacks that rely on OpenGL-specific features

🎮 How to Use

Install Fabric Loader for Minecraft 1.21.11

Download Java 21 if not already installed

Drop all mods into your mods folder

Launch the game once to generate configs

(Optional) Tweak individual mod configs via ModMenu

Recommended JVM Arguments:

-Xms4G -Xmx8G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200

❓ FAQ

Q: Why VulkanMod instead of Sodium?

A: VulkanMod provides better performance on modern GPUs by using Vulkan directly instead of OpenGL. However, it’s less compatible with shaders and some mods.

Q: Can I add shaders?

A: No. VulkanMod is incompatible with Iris/Optifine shaders.

Q: Can I add content mods (Biomes, Mobs, Tech)?

A: Partially, with significant limitations.

This pack uses VulkanMod, which replaces Minecraft’s rendering engine from OpenGL to Vulkan. While many content mods work fine, any mod that makes direct OpenGL calls will crash your game.

Q: My game crashes!

A: Ensure you have Java 21 and a Vulkan-compatible GPU. Check the crash report and disable VulkanMod if needed.

Q: How do I disable VulkanMod?

A: Remove vulkanmod.jar from your mods folder. The pack will still work with default OpenGL rendering.
