About this Mod

Low Latency

中文

This mod is designed to reduce input latency when the GPU is full load and the CPU is not, inspired by NVIDIA Reflex.

When the gpu is full load and the CPU is not, a frame queue backlog will build up, the input latency will increase.

This mod estimates input latency based on historical CPU and GPU frame times, and waits before input events to ensure the frame queue will not build up, which reduces input latency.

This project is in its early stages, which may result in reduced frame rates or increased latency. You can adjust the ‘wait time offset’ in the config menu to alleviate this issue.

You can enable/disable low latency feature in config menu.

Frequently Asked Questions

Does Low Latency need to be installed on the Minecraft server?

No. Modrinth marks Low Latency as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Low Latency require?

Use a file for fabric, neoforge and your exact Minecraft version. Supported versions include 26.2, 26.1.2, 26.1.1. Files for different loaders are not interchangeable.

Low Latency is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
