Replacing the underlying VM with luajit speeds up the entire game.

Supports saves up to 2000 days with numerous mods, without frame drops or lag

Installation:

Open the mod's folder, typically located at steamapps\workshop\content\322330\3444078585, and run install.bat (for Windows) or linux.sh (for Linux and macOS).

Recommended Settings:

Client: Set rendering frame rate to 120, logic frame rate to 60, and client synchronization frame rate to 60.
Server: Set rendering frame rate to 120, logic frame rate to 60, and add -tick_rate 60 to the command line.
Features:

JIT for global script acceleration.
Disables full garbage collection, which is the main cause of game stuttering.
Enables inter-frame garbage collection to perform garbage collection during spare time between frames.
Unlocks frame rate options: 120/144/165/200/240 FPS.
Unlocks logic frame rate options: 45/60/75/90/105/120 FPS.
Allows modification of the client network synchronization frame rate (default is 10 FPS and cannot be changed without this mod).
Fully compatible with the Snowstorm series of encrypted mods.
Bugs:

Except when saving the game, if you experience lag, first check your CPU usage. If it’s at 100%, you might need a better CPU. Otherwise, please report the issue. I don’t think there will be any lag.

Problem-Solving:

Rerunning the installation script can solve 99% of problems, usually caused by version inconsistencies.
If the progress bar in the "patch process" window gets stuck, add -disable_progress to the startup parameters and try again. This issue is caused by system problems where the timer function is malfunctioning.
If you can’t enter the game at all, you may need to install the VC2022 runtime library:

Uninstallation:

Use the uninstall button in the configuration interface, or
Delete bin64/winmm.dll in the game directory.

Use the package from GitHub, as the Steam Workshop only provides the Windows version:
