Frequently asked

How do I install Default Optimization DO?

Use a launcher that imports packs, such as Prism Launcher, the Modrinth App or the CurseForge app, and open the pack file with it. The launcher installs the right loader and mods for you; installing a pack's mods by hand is the error-prone way.

Where do I download Default Optimization DO safely?

Start with the author's page on CurseForge, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.

Which Minecraft versions does Default Optimization DO work on?

The author has not declared a supported version in the metadata we sync, so there is nothing here we can state as fact. Check the project's own page before installing it, and treat an old modpack with no declared version as untested on modern Minecraft.

Details from CurseForge, where the author last updated it on 17 Aug 2026. We do not host files and we do not republish descriptions; every download link points at the author’s own release.

Not indexed yet. Score 45 against a threshold of 55. The page still exists and is still linked; it simply carries noindex until we hold more.
