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!

Options

Option
Description
Vanilla
Modpack
Reason for Change
autoJump
Makes the player jump when approaching a 1-height block
true
false
Many people consider it annoying and therefore disable it (1.19.4 parity)
snooperEnabled
Toggles Snooper, a hardware analytics service. The setting was removed in 1.13 but it still exists in options (and defaults to enabled) for some reason.
true
false
Just in case you use the same profile on MC 1.13 or older, to improve privacy. In 1.18+ Debugify is used to disable the new telemetry.
darkMojangStudiosBackground
Makes the splash screen black and white
false
true
Black background is less intrusive than red, partial Bedrock Edition parity
simulationDistance
Redstone and mob spawning distance
12
6
Better performance regardless of the rendering distance you use
guiScale
Size of the menu and interface elements
0
3
3 is usable on all screens, 0 (Auto) can get too large on Full HD and larger screens
maxFps
The maximum framerate
120
260
260 means "unlimited", this is changed for better UX when VSync is disabled by the user (on fast computers/monitors)
resourcePacks
Adjusts which resource packs are enabled by default
[]
¹
Enabled mods' default packs and FO-exclusive Mod Menu Helper
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
skipMultiplayerWarning
Whether to skip the legal disclaimer when opening the multiplayer screen
false
true
I expect my users to already know that the third party servers are not owned or monitored by Mojang Studios or Microsoft. A more relevant warning is added to Realms by No Chat Reports.
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
chatPreview
Whether to display the Chat Preview toolbar
1
0
Disabled for privacy to avoid sending your chat to the server as you type, avoids related annoyances like toasts and warnings, 1.19.3 parity

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...).

    Find the actual bug in Mojang's bug tracker​

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, better grass and zoom:
  1. 1.
    Click Mods
  2. 2.
    Read the descriptions of the mods to see what they do
  3. 3.
    If the pencil is blue, you can configure the mod by clicking the config button
    config
    ​
    • If you don't see any pencils, 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.
If you have more questions about the mods, chat with us on Discord!​
