FAQ

Q: I need help, have questions, or something else.
A: You can join the Discord server.

Q: Where can I download this mod?
A: Modrinth, CurseForge, GitHub. You can also find unstable builds at GitHub Actions. You will need a GitHub account to download these.

Q: This mod doesn't speed up anything.
A: The effect may not be noticeable on high-end PCs. This mod is designed primarily for low-end devices. Nevertheless, there is a video.

Q: Which mod loaders are supported?
A: Forge, Fabric, Quilt, NeoForge, Legacy Fabric, and Ornithe (for both Fabric and Quilt).

Q: Which versions are supported?
A: Minecraft 1.8 or newer. There may be a backport to older versions in the future.

Q: Where are the Forge, Fabric, Quilt, NeoForge, etc. versions?
A: All in the same file.

Q: Do I need Fabric API or Quilt Standard Libraries?
A: No, but you can have it installed for other mods.

Q: Is this mod open source?
A: Yes. (Licensed under MIT License)

Q: Is this mod stable for use?
A: It should be. No guarantee, though. At least it should not break your worlds. You can always uninstall the mod and load them without Ksyxis.

Q: Is this mod client-side or server-side?
A: This mod works on the logical server side. That is, it does have an effect in singleplayer and on a dedicated (standalone) server. It has no effect on the client when playing in multiplayer. You can install it into your client or your server without any requirements for it to be installed on the other side.

Q: How to force-load chunks for ticking if spawn chunks have been removed?
A: If you really need ticking chunks, load individual chunks with the /forceload vanilla command in 1.13 or newer. For older versions, you can search for some mod that force-loads chunks.

Q: I've found a bug.
A: Report it here. If you are not sure if this is a bug, you can join the Discord.

Q: Can I use this in my modpack?
A: Sure. Credit (e.g., a link to the mod's GitHub page) is appreciated but is not required. Monetization and redistribution are allowed as per the MIT License.

Q: It says Ksyxis: No Mixin found.
A: If you're using Forge 1.15.2 or older, you may need to install MixinBootstrap, MixinBooter, UniMixins, or any other Mixin provider of your choice. If you're using Forge 1.16 or newer, any version Fabric/Quilt/NeoForge/Ornithe, you don't need to install anything, and this is a bug.
