About this Mod

Registers Minecraft's main thread as a game with MMCSS on Windows, which helps to improve performance and general smoothness while multitasking. The effects of this are most significant on older or lower-end hardware where system resources are scarce, and may not be as noticeable on modern CPUs.

Because this mod does not depend on any Minecraft code and only relies on Fabric to call the Windows API while loading, it works on all* versions, including legacy ones via Legacy Fabric and Babric. Additionally, as it simply does not do anything when running on other platforms, it is safe to include in packs.

* Java 8 or above is required for legacy versions.

Frequently Asked Questions

Does Windows Priority Boost need to be installed on the Minecraft server?

No. Modrinth marks Windows Priority Boost 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 Windows Priority Boost require?

Use a file for babric, bta-babric, fabric, legacy-fabric, quilt and your exact Minecraft version. Supported versions include 26.4-snapshot-2, 26.4-snapshot-1, 26.3. Files for different loaders are not interchangeable.

Windows Priority Boost 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.
