Description

VulkBatch

VulkBatch is a client-side rendering optimization mod for Minecraft 26.3. It is designed to address micro-stutters and frame drops that occur in scenarios with high entity and particle density.

How It Works

During heavy rendering phases, Minecraft constantly allocates and discards memory for every frame, which leads to increased Garbage Collection (GC) overhead. VulkBatch intercepts the BufferBuilder pipeline to reuse memory allocations rather than letting them go to the garbage collector. By reducing this memory churn, it prevents the sudden GC spikes that cause frame pacing issues.

Key Features

  • 1% Low Frame Rate Stability: Specifically targets and improves frame pacing during intense combat, explosions, and large-scale mob farms.

  • Reduced GC Overhead: Eliminates memory allocation spikes caused by high-frequency rendering.

  • Dual Backend Support: Fully compatible with both the newer Vulkan and the legacy OpenGL rendering backends.

  • Zero-Config: No menus or toggles. Drop the .jar into your mods folder and it works out of the box.

Compatibility & Requirements

  • Minecraft: 26.3

  • Dependencies: Fabric Loader, Fabric API

  • Environment: Client-side only. It is completely safe to use on multiplayer servers, and server-side installation is not required.

Ongoing Support

This mod is actively maintained. As Minecraft 26.3 continues to evolve and new rendering bottlenecks are identified, I will continue to push updates to ensure optimal performance and compatibility. Feedback and bug reports are always welcome to help improve the mod in future releases.
