AcceleratedRendering-reFabricated
by ZhuRuoLing
Entities with many vertices can stall the CPU during rendering, and AcceleratedRendering-reFabricated moves part of that work onto the GPU for Fabric players on client builds.
What it does
The mod targets entity rendering on the client. Minecraft's older immediate rendering mode uploads and transforms vertices on a single render thread, which can leave the CPU and GPU idle while frames take longer than they should. AcceleratedRendering-reFabricated builds a separate rendering pipeline that keeps copies of the original vertices, transforms the meshes in parallel on the GPU through compute shaders, and then draws the transformed vertices with their original shader. The aim is to take that transform load off the CPU, which matters most for large amounts of entities and complex modded models.
The mod needs Fabric API and Forge Config API Port, both of which must be installed alongside it. It is client-side only, so servers do not need it and players can join a server without it. The pipeline depends on OpenGL 4.6 and newer hardware, and the author has tested it on several recent NVIDIA, AMD and Intel adapters as well as laptops, with mobile devices listed as supported. Acceleration can be turned off, which the author recommends when compatibility with other mods is the priority. The mod is open source under the MIT License.
Key features
GPU vertex transforms
Entity vertices are transformed in parallel on the GPU with compute shaders, instead of on one CPU render thread.
Cached original vertices
A separate pipeline keeps the original vertices so transformed meshes can be drawn with their original shader.
Shader pack support
The acceleration works alongside shader packs, with Iris Shaders named as supported by the author.
Toggleable acceleration
The acceleration features can be disabled, which the author says gives better compatibility with other mods.

How it compares
AcceleratedRendering-Ported is a Client-side only mod under the MIT License, but it is not open source and targets 1.21.4 – 26.1. OptiPainting is a different kind of optimization: it is client-side only, open source under the GNU Lesser General Public License v3.0 or later, and published for 1.19 – 1.20.6, so it does not cover the 1.20 – 1.21.1 range of this mod.
