Install in the game only; not needed on the server
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.*
