Smooth Boot Mod (1.21.1, 1.20.1) – Improve and Tweak Minecraft CPU Scheduling

If you have a PC with a older or lower end CPU (ex. CPUs with 8 or less threads), you may have noticed that Minecraft takes up 100% of the CPU when loading into the title screen, causing cursor stutter and makes multitasking painfully difficult. Smooth Boot Mod solves this problem completely, and loading should be much smoother and potentially faster as well. Optimize Minecraft loading performance to be smoother on low end systems and scale better on high end systems.

Minecraft uses executors to run multithreaded tasks. The problem is that the tasks that are ran during loading are quite heavy on the CPU, so it leads to 100% CPU usage. And, some of the tasks do not necessarily benefit from multithreading. Smooth Boot fixes these problems by change the parameters of the executors, including the number of threads they use and the priority of each thread.

The mod should be compatible with all mods including Optifine. However, it’s worth noting that the mod uses mixin overwrites on some methods used for loading the game.

Features:

• Change amount of threads used for loading.
• Change priority of threads used by Minecraft.
• Auto config menu to change config from in game.
