About this Mod
Low Latency
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.

Low Latency server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.
Is Low Latency compatible with fabric and neoforge?
Low Latency officially supports fabric, neoforge for Minecraft 26.1.2, 26.1.1, 26.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Low Latency – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Low Latency consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
