Vector-render
Vector-render lets players on Minecraft 1.20.4 lower GPU load by capping frames to the monitor refresh rate, using rendering code adapted from a later release.
What it does
Players who run 1.20.4 on a high refresh rate monitor can use Vector-render to lower GPU load. It caps the frame rate to the monitor's refresh rate and lets the in-game FPS limit be set to Unlimited, so the GPU no longer runs at full load while producing frames the display never shows. Only the client needs the mod, and it changes nothing on the server side.
The mod carries a newer rendering pipeline back to 1.20.4. It adds GpuDevice, RenderPass and CommandEncoder abstractions and a pipeline-based shader system with RenderPipeline and CompiledRenderPipeline classes. A required library must sit alongside it on Fabric.
Files are published for Fabric only, with 2.0.0 for 1.20.4 as the latest build, dated 2026-06-28. The code is open source under the Apache License 2.0, and public source code and an issue tracker exist.
Key features
Frame rate cap
The frame rate is capped to the refresh rate of the monitor, so an Unlimited in-game setting does not keep the GPU at full load.
Rendering pipeline backport
A shader pipeline built around compiled render pipelines replaces the older 1.20.4 drawing path once the graphics context starts.
Held item alignment
The gap between the arm and a held sword, axe or other non-shield item is corrected, so the item sits flush with the raised arm.
