Chandler's Optimizations
by chandler3
Chandler's Optimizations changes how the beta terrain renderer builds and draws chunks, and lifts the render distance cap to 64 chunks.
What it does
The mod revises several pieces of the old beta-style chunk renderer. Its rebuild queue avoids scanning and sorting large numbers of chunks over and over, and the renderer keeps more of its internal terrain state in caches instead of recalculating it on every frame. Its stated aim is to cut wasted CPU work, with smoother performance and faster terrain loading, most noticeable at high render distances.
Several options control the renderer. Frustum priority loads chunks inside the view first, and Multidraw makes fuller use of the GPU. Players report that Multidraw, Terrain Renderer and Frustum Priority are most stable left off, and that Frustum priority speeds up terrain loading at some cost in frame rate. The settings are found at the bottom of the Video settings under Chandler's Optimizations, and an in-game profiler overlay with hotkey controls shows frame time and chunk rebuild work.
The mod runs on BTA Babric and supports only b1.7.3. Two dependencies are listed, the BTA Fabric 7.3 04 release and HalpLibe 5.4.0. It is client-side only, so only the client needs it. Files were first published on 2026-05-13 and last updated on 2026-08-08, and snapshot builds are published. The mod is released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license and is not open source.
Key features
Faster chunk rebuilds
A smarter rebuild queue handles chunk updates without repeatedly scanning and sorting large numbers of chunks.
Higher render distance
The render distance limit is raised to 64 chunks, and the renderer is reworked to cope with the larger range.
Frustum and Multidraw options
Frustum priority loads visible chunks first, and Multidraw makes fuller use of the GPU, each as a separate setting.
Built-in profiler overlay
An in-game overlay shows frame time and chunk rebuild work, with hotkey controls for the benchmark tools.
Use cases
High render distance play
Players who want distant terrain at large render distances can use the renderer changes to load chunks with less wasted work.
Who it’s for: Players on BTA Babric who run the beta version b1.7.3 and want to measure or tune terrain rendering performance. Only the client needs the mod.

What the author says
Chandler’s Optimizations improves Better than Adventure’s terrain renderer so larger render distances are more practical. The mod raises the render distance limit to 64 chunks and reworks parts of the old beta-style chunk renderer to reduce wasted CPU work. It uses a smarter chunk rebuild queue, avoids repeatedly…
