Overview

This release brings Vectors' supported Minecraft versions and loaders onto a unified codebase, aligning them with the latest 1.5.0-alpha.22 architecture.

It also introduces improvements to chunk worker management, preset configuration, and terrain batching to improve rendering performance and maintain more consistent behavior across supported versions.

Changes

Performance Improvements

• Dynamic Chunk Workers: Chunk worker threads are now configured dynamically based on the available CPU cores, with a maximum of six workers.
• Improved Preset Handling: Fixed an issue where changing optimization presets could reset or incorrectly modify the terrain batching setting.
• Preset Tuning: The Performance preset uses six chunk workers, while Balanced uses four.
• Terrain Batching: Improved the Multi-Draw Indirect (MDI) rendering pipeline to reduce draw call overhead and help alleviate CPU-side rendering bottlenecks.

Version and Loader Updates

• Updated the Minecraft 26.3 NeoForge build to the latest Vectors codebase.
• Updated the Minecraft 26.3 Fabric build to version 1.5.0-alpha.22.
• Synchronized the 26.2, 26.1.2, 26.1.1, 26.1, and 1.21.1 builds with the unified release.

Configuration

• Terrain Batching remains enabled when switching between Balanced, Performance, and Quality presets.
• You can review your optimization settings in the Vectors configuration menu by pressing F8 in-game.

Recommended Checks

After updating, open the Vectors configuration menu and verify that Terrain Batching and Chunk Threads are enabled under the optimization settings.

Note: Vectors is still in alpha. Performance gains may vary depending on your hardware, Minecraft version, and mod configuration.
