UniTweaks
With UniTweaks installed, Minecraft Beta b1.7.3 gets a bundle of fixes and option changes for network timing, focus handling, autosave and input on the Fabric and Babric loaders.
What it does
UniTweaks bundles several tweaks for the b1.7.3 client. It turns on the TCPNoDelay flag for network sockets and removes an artificial delay that held back outgoing packets for up to 392 milliseconds. It also turns off the game pausing when the window loses focus, and it disables controller initialization code that does nothing useful. Raw input is available as an option, and the autosave interval default can be changed from its 30 second value.
The mod also lets players change the default resource URL, which points at Betacraft, and lets server owners disable loading of certain dimensions. Installing it requires Glass Config API, and Glass Config API must be present for the mod to load. The code is open source under the MIT License, and source code and an issue tracker are linked publicly. Files are published for Fabric and Babric, only for b1.7.3, and snapshot builds are published as well.
Key features
Network packet tweaks
TCPNoDelay is enabled on network sockets, and a packet speedup patch removes the delay that held back packets.
Focus and pause control
The game no longer pauses when its window loses focus, so switching windows does not stop play.
Autosave interval
The autosave interval default of 30 seconds can be changed to suit a player's preference.
Raw input and controllers
Raw input is available, and controller initialization code that serves no function is disabled.
Server dimension loading
Server owners can disable loading of certain dimensions, and the resource URL default can be changed.
