Roblox FastFlags Presets Bloxstrap

Caution

FastFlags are extremely powerful, being that they are intended to only be used by Roblox engineers. While they can be very useful, they can cause issues with stability and functionality if you don't know what you're doing.

Version: 2.0.0 [UPDATE]

  • V2 Release
  • Submit an issue if you need help!
  • Want to add your preset? Fork and make a PR!

Bloxstrap How to Use:

  1. Open the Bloxstrap Menu.
  2. Navigate to Fast Flags >> Fast Flags Editor >> Add New >> Import Json.
  3. Paste in the JSON.
  4. Save and your good to go!

Normal Roblox Bootstrapper How to Use:

You can also do Roblox Studio
  1. Navigate to your Roblox Installation directory. Typically found at %localappdata%\Roblox\Versions\ or C:\Program Files (x86)\Roblox\Versions.
  2. Identify the folder version-xxxxxxxxxxxxxxxx containing RobloxPlayerBeta.exe You can do this for Roblox Studio too.
  3. Create a new folder named ClientSettings. Inside this folder, place the file ClientAppSettings.json.
  4. Paste the JSON into ClientAppSettings.json. (You can utilize ChatGPT to format multiple JSONs for clarity if needed)
  5. Save and you're good to go!
Do note that after roblox updates you have to do this process again

I don't see a difference between these two, Please don't blindly paste Fast Flags that you don't know what they do & Don't buy those "FPS" & "PING" flags.
