Frequently Asked Questions
Question: Why hide F3 elements from other mods? Didn't their authors add them intentionally? Answer: While some mods do add information useful for debugging, most players don't need this data and it only distracts from what's truly important. However, if you're planning to report an issue with one of the mods, be sure to turn their debug information back on if the developers request a screenshot!
Question: Can you add a toggle for ImmediatelyFast? Answer: ImmediatelyFast already has a built-in setting option to disable debug information.
Question: Can you add support for another mod xyz? Answer: Create a request on GitHub with the mod's name, and I'll look into the possibility of adding it.
Question: Neoforge/Forge version? Answer: Clean F3 is currently being developed only for Fabric. However, for use on NeoForge, you can use Sinytra Connector. Unfortunately, this doesn't work with Forge 1.20.1.
