Changed options

Fabulously Optimized changes some default options of Minecraft to improve your gameplay.

Because the pack is using YOSBR, the options will only change if you do not have options.txt or mod-specific files in config folder already, e.g. by using a clean profile. That also means you can freely update the pack without losing your settings!

P.S. This table has 5 columns. Scroll right if you can't see them!

Options

Option	Description	Vanilla	Modpack	Reason for Change
advancedItemTooltips	Enables "advanced" tooltip info on items - item ID and durability, and exact color hex code for dyed armor	false	true	These are useful for much more than just debugging - if you're using commands, want to know the exact durability value, learning English, etc. Plus, this setting is hidden in the debug menu, so many people might not know about it.
darkMojangStudiosBackground	Makes the Mojang Studios splash screen white-on-black instead of white-on-red	false	true	Black background is less intrusive than red, partial Bedrock Edition parity
enableVsync	Toggle VSync, a FPS-limiting system	true	false	Disabling VSync by default helps users instantly see the benefits of FO, reduces input lag and increases framerate when using shaders. The benefits of enabling or disabling it vary by system; also note that FO has an option to use Adaptive VSync on some systems.
guiScale	Size of the menu and interface elements	0	3	3 is more usable on most screens, 0 (Auto) can get too large on Full HD and larger screens, including most Macs' "Retina" displays
incompatibleResourcePacks	A list of resource packs that have been forcefully enabled, despite being marked as incompatible	[]	(varies)	Mod-provided resource packs that have old manifest version but are known to be compatible. Usually contains just Continuity's resource packs, but values may vary by FO version.
joinedFirstServer	Whether to display the hint for Social Interactions	false	true	I expect my users to already know that Social Interactions can be opened with P; the screen is easily discoverable by the "Player Reporting" button
maxFps	The maximum framerate	120	260	260 means "unlimited", which allows you to see the full FPS that your system is capable of
onboardAccessibility	Indicates whether the user has not seen the accessibility onboarding screen	true	false	Minecraft already has an easily accessible accessibility button in the main menu, this screen just creates annoyances for the majority who don't need it. Read more about accessibility in FO
operatorItemsTab	Shows operator-only items (command blocks, lights, barriers, etc.) in a Creative inventory tab, when you have operator access (/op)	false	true	It is useful and it only appears when you have the permission for it, so it's weird Mojang even made it an option
resourcePacks	Adjusts which resource packs are enabled by default	[]	¹	Enabled mod-provided and FO-exclusive resource packs by default
lang	Adjusts the game's language	en_us	(your OS language)	Enables user's system language by default, for usability, accessibility and discoverability purposes - courtesy of Language Reload. Not available for all launchers and operating systems.
simulationDistance	Redstone and mob spawning distance	12	6	Better performance regardless of the rendering distance you use
skipMultiplayerWarning	Whether to skip the legal disclaimer when opening the multiplayer screen	false	true	Users are already expected to know that the third party servers are not owned or monitored by Mojang Studios or Microsoft.
telemetryOptInExtra	Sets the telemetry (analytics data collection) toggle to "minimal".	false	false	While "minimal" is the default right now anyway, it may not always be the case, hence the enforcement by FO. Debugify is used to disable it entirely though, so this is also just a fallback.
tutorialStep	The next step of tutorial hints	movement	none	If you know how to install a modpack, you probably don't need those tutorials anymore

Telemetry

Telemetry Data Collection, previously known as Snooper, refers to Minecraft's and potentially mods', launchers' methods of collecting analytics about the user, usually in a limited form to preserve privacy. Minecraft's telemetry options are detailed here.

While telemetry is not always bad, as it may help developers better support their content for users' devices (e.g. to see where performance can be improved) it can be unwanted and unexpected for privacy concerns.

As of 1.20.2, Minecraft does not have an option to fully disable telemetry, so in this modpack such option is added by Debugify. The reason for disabling vanilla telemetry is that

1. it collects too much data even in minimal configuration (e.g. user's Xbox ID)

2. it skews Mojang's data due to being modded - Mojang may see that users already have good performance, but it does not actually reflect the vanilla game

The modpack's stance is to disable all forms of telemetry by default, letting users to choose to opt-in to it manually when wanted. However, it is important to note that the modpack cannot disable any telemetry collected by user's launcher or operating system.

Keybinds

P.S. This table has 5 columns. Scroll right if you can't see them!

Option	Description	Default	Modpack	Reason for Change

Zoomify: Zoom	Zooms the view when the key is held	v	c	This key is more often used for zoom
Zoomify: Secondary zoom	Activates the secondary zoom option	F6	none	Not needed for most players
Iris: Reload Shaders	Reloads the applied shaders	r	none	Not needed for most players
Iris: Shaderpack Selection Screen	Opens the shader selection screen	o	none	Not needed for most players
Iris: Toggle Shaders	Disables or enables shaders	k	none	Not needed for most players
FabricSkyboxes: Toggle mod	Disables or enables custom skyboxes	Numpad 0	none	Not needed for most players

Resource packs

Fabulously Optimized enables relevant mod-provided resource packs and bundles some resource packs for better experience.

• Mod Menu Helper (FO-exclusive) - explains what each mod does in a consistent and clear way on Mod Menu
• Chat Reporting Helper - explains chat reporting in a clear way by simplifying vanilla and No Chat Reports tooltips and No Chat Reports icons
• Fast Better Grass - imitates OptiFine's "Better Grass" (fast mode)
• Translations for Sodium - adds unofficial translations for Sodium (video settings)

The resource packs use minimal resources, can be translated to your language and they will work with other resource packs.

Fixed bugs

Fabulously Optimized includes some mods that fix vanilla bugs. Similar to the mod inclusion policy, they must be meaningful to 70%+ users to get enabled (e.g. FPS drops, crashes, platform-specific annoyances...).

Requesting a bugfix

Want to get a bug fixed in Fabulously Optimized? Here's what you'll need to do:

1. Find the actual bug in Mojang's bug tracker
2. Request it or look at its status on Debugify's bug tracker
3. Once implemented (or confirmed to be) in Debugify, request an option change in FO
4. Describe the bug, mention the mod that fixes it and why it is important to 70-80% of users

5. If accepted, expect the fix to be enabled in the next version of FO :)

Configuring mods

The modpack is already configured for the best performance and simplest experience for most users.

If you want to configure something, you'll most likely find it on Options... → Video Settings.... If you have a powerful computer or monitor, you may want to disable Vsync there.

For other things like dynamic lights, shaders and zoom:

1. Click Mods

2. Read the descriptions of the mods to see what they do

3. If 🛠️ or ✏️ is blue, you can configure the mod by clicking the config button

   • If you don't see the 🛠️ or ✏️ emoji, you don't have the Mod Menu Helper resource pack enabled for some reason. Click Done → Options... → Resource Packs... → ⏵ on "Mod Menu Helper.zip" → Done → go to point 1 of this tutorial

If you need to disable a mod, see this wiki page.
