Purely Optimized - Vulkan

This is a lightweight Fabric optimization modpack built around VulkanMod, using the Vulkan graphics API instead of Minecraft's default old OpenGL renderer while combining several carefully selected performance mods to maximize FPS without changing vanilla gameplay.

Instead of changing mechanics, adding content, or modifying the game's visuals, this modpack only includes performance improvements and quality optimizations.

This is a client-side modpack. It can be used on vanilla and modded servers unless a server explicitly disallows client mods.

Why Vulkan?

Unlike most optimization packs that rely on OpenGL, Purely Optimized - Vulkan is built around VulkanMod. On systems with good Vulkan support, this can provide smoother frame times and significantly higher FPS while preserving the vanilla Minecraft experience.

Who is this for?

This modpack is ideal for players who want:

• Maximum FPS
• Lower CPU usage
• Better multiplayer performance
• Vanilla gameplay
• A lightweight alternative to larger optimization packs

Features

• Vulkan rendering using VulkanMod instead of OpenGL
• Higher FPS and smoother frame times
• Memory and CPU optimizations
• Faster chunk rendering and loading
• Better performance on multiplayer servers
• Fully vanilla gameplay
• Small, lightweight mod list

Included Optimizations

This modpack combines Vulkan rendering with several well-known performance mods, including:

• VulkanMod + Not Enough Vulkan - For the rendering engine.
• FerriteCore - Reduces memory usage.
• Lithium - Game logic optimizations.
• ImmediatelyFast - More efficient GPU usage.
• Entity Culling - Culls hidden blocks and entities to reduce rendering work.
• More Culling - Improves several block and rendering culling techniques.
• Krypton - Optimizes Minecraft's networking.
• Very Many Players - Improves multiplayer performance and networking efficiency.
• Packet Fixer - Fix various problems with packets, NBT, and timeouts.
• Clumps - Clumps XP orbs together to reduce lag.
• ScalableLux - Fixes lighting performance and lighting errors.
• XXLPackets - Bigger Packet Size Limit.
• Debugify - Fixes Minecraft bugs found on the bug tracker.
• Fast IP Ping - Reduction in time of connecting to the server.
• Particle Core - Optimizing particles.

along with the required Fabric libraries.

Each mod was selected to improve performance while maintaining compatibility and preserving the vanilla Minecraft experience.

Expected Performance

Because every PC is different, performance gains will vary.

On hardware that supports Vulkan well, many players can expect significantly higher FPS and smoother gameplay compared to vanilla Minecraft. Depending on your hardware, world, and graphics settings, some users may see FPS improvements of up to 2x–3x compared to vanilla Minecraft.

Summary

If you're looking for a lightweight, vanilla-friendly optimization pack built around Vulkan rendering, Purely Optimized - Vulkan is designed to deliver the highest performance with minimal overhead.
