Smooth Boot (Reloaded) Mod is an optimization mod that tweaks Minecraft CPU scheduling and executor thread behavior for Minecraft Forge. It supports Minecraft 1.20.1, 1.19.4, 1.19.3, 1.19.2, and 1.18.2.
If your PC struggles when Minecraft reaches the title screen, Smooth Boot (Reloaded) is aimed at that exact pain point. Instead of letting loading tasks crowd out everything else, it adjusts how those tasks are scheduled so startup can feel less stuttery and easier to multitask around, and its 3 million+ Modrinth downloads suggest a lot of players have found that tradeoff useful.
Key Features of Smooth Boot (Reloaded) Mod
- Configurable loading thread count - The mod lets you change how many threads Minecraft uses while it is loading. That matters because the default behavior can be too aggressive on CPUs with fewer threads, especially if you want to keep the rest of your system responsive while the game starts.
- Thread priority control - You can adjust the priority of Minecraft's loading threads instead of leaving everything at the default level. In practical terms, this gives you a way to keep the launcher and the rest of your desktop from feeling like they are fighting Minecraft for attention.
- Focus on startup CPU pressure - The mod is designed around the heavy CPU load that happens during the journey to the title screen. That is useful because startup bottlenecks often feel worse than in-game slowdown, especially when the system is already busy with other applications.
- Better multitasking during load - One of the biggest quality-of-life wins here is that Minecraft is less likely to monopolize the machine while it boots. If you alt-tab, listen to music, or keep browser windows open, the smoother load behavior can make the whole session feel less hostile to your PC.
- Potentially smoother and faster-feeling loading - The mod is intended to make loading feel more controlled, and that can also make startup seem faster in some setups. I would not frame it as a universal speed boost, but it does appear to be a sensible fix for the kind of loading stutter that frustrates lower-end systems.
- Open-source and modpack-friendly - Smooth Boot (Reloaded) is a free and open-source project, and the author states that it can be included in modpacks. That makes it a practical choice if you are curating a Forge pack and want a performance-oriented mod that is easy to redistribute.

How to Install Smooth Boot (Reloaded) Mod
- Install Minecraft Forge for the same Minecraft version you plan to play.
- Download the Smooth Boot (Reloaded) file that matches your version, such as 1.20.1, 1.19.4, 1.19.3, 1.19.2, or 1.18.2.
- Open your Minecraft game directory and find the
modsfolder. If you do not have one yet, create it after setting up Forge. - Place the mod file into the
modsfolder, then launch Minecraft using the Forge profile. - If you want to fine-tune the experience, check the mod configuration after the first launch and adjust the worker-thread settings to fit your CPU.

What's New
- The mod now uses a specific number of main worker threads that you can change in the configuration.
- Earlier updates relied on the number of available threads, which could lead to weaker performance in some cases.
- The change shifts the focus toward more deliberate thread management instead of automatically using every available thread.
- This update is meant to give you more predictable control over how Minecraft behaves during loading.
Pros and Cons
Pros
- Targets a common problem: Minecraft using too much CPU during startup.
- Lets you tune thread count and thread priority instead of relying on defaults.
- Can make multitasking feel less painful while the game is loading.
- Supports several recent Forge-compatible Minecraft versions.
- Open-source and usable in modpacks.
Cons
- Forge only, so it is not the right choice for other loaders.
- Its benefits are most relevant on older or lower-thread CPUs.
- It focuses on loading behavior, so it is not a broad all-in-one performance mod.
Alternatives to Smooth Boot (Reloaded) Mod
- Embeddium - A performance-focused mod many players consider when building a smoother Forge setup, especially if they want broader optimization alongside loading tweaks.
- ModernFix - A complementary optimization mod to compare if you want to reduce friction across more parts of the game, not just startup behavior.
- FerriteCore - A good option for players looking at memory-saving performance improvements as part of a wider optimization stack.

Frequently Asked Questions
What does Smooth Boot (Reloaded) actually do?
It adjusts Minecraft's loading executors so startup can be less demanding on the CPU. The goal is to reduce the period where the game monopolizes system resources and makes the desktop feel choppy.
Is Smooth Boot (Reloaded) only for Forge?
Yes, this mod is listed for Minecraft Forge. The supported versions provided here are all Forge builds, so it is not the right pick for a different loader.
Which Minecraft versions are supported?
It supports Minecraft 1.20.1, 1.19.4, 1.19.3, 1.19.2, and 1.18.2. If you are on one of those versions and using Forge, you are in the intended compatibility range.
Will this help if my CPU is older or has fewer threads?
Yes, that is the scenario it is most clearly aimed at. The mod description specifically calls out lower-end CPUs, including processors with 8 or fewer threads, because those systems are more likely to feel the load spike.
Can I use Smooth Boot (Reloaded) in a modpack?
Yes, the author says it can be included in modpacks. That makes it a practical performance mod for pack makers who want to improve loading behavior without restricting redistribution.
Is this an official Smooth Boot release?
No, it is an unofficial fork of Smooth Boot. That matters because you should treat it as a community continuation rather than the original project.
Does it add new gameplay content?
No, it is an optimization mod rather than a content mod. Its purpose is to change how Minecraft handles CPU work during loading, not to add blocks, items, or mechanics.
Can I change the settings?
Yes, the mod exposes thread-related options in its configuration. The changelog also notes that the main worker thread count can now be set specifically, which gives you more control than relying on the default behavior.
