PROMOTE OUR CLEAN LIST TO NORMAL USERS

https://github.com/fastvariable/nvrmaintain

[!CAUTION] Fast Flags 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.

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, add a 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

Android Rootless Roblox (MT Manager) How to Use:

[!CAUTION] Roblox is implementing anti-tamper measures on mobile. Proceed at your own risk.

1. Download a Roblox APK file from a trusted source.
2. Open MT Manager and navigate to the Roblox APK file.
3. Tap on the APK and select View. /assets >> main.1.com.roblox.client.obb and click on it then Archive Viewer.
4. Create a new folder named ClientSettings.
5. Place your ClientAppSettings.json file inside the ClientSettings folder. (You can use ChatGPT to help format JSON files for clarity if needed)
6. Tap on the back button (..) to exit the archive. It will prompt you to update the file main.1.com.roblox.client.obb—click OK.
7. Long-press the Roblox APK file, choose Sign File, and click OK with default settings.
8. Install the modified APK.

   This process must be repeated whenever a new Roblox build is released, as the modifications will not carry over to new updates.

How to Use _PlaceFilter

1. Add _PlaceFilter after the Fast Flag name.
2. Add a semicolon after the Value (;). Examples: True;, 1;.**
3. Include a Place ID after the semicolon. Examples: True;4483381587, 1;4483381587.
4. Your configuration is complete!**

MTU

[!TIP] Identify the Current MTU

• Windows: Open Command Prompt and type netsh interface ipv4 show subinterfaces.
• Linux: Use ifconfig or ip link show to find the current MTU of your network interface.

[!TIP] Determine the Optimal MTU

• Ping Test: Use the ping command with the -f flag (to avoid fragmentation) and the -l (or -s on Linux) flag to set the packet size.
• Example for Windows:

  ping roblox.com -f -l 1472

• Example for Linux:

  ping -s 1472 -M do roblox.com

• Start with a packet size of 1472 bytes, then reduce by 10-12 bytes if needed until you find the largest size that doesn't fragment. Add 28 bytes to this number to get the optimal MTU.

  {
  "DFIntConnectionMTUSize": "MTU_HERE"
  }

  No Internet Disconnect

  [!NOTE] You will still be kicked but the message wont show.

  {

  Quick Game Launch

  [!CAUTION] This can cause some bugs

  {
  "FFlagEnableQuickGameLaunch": "True"
  }

  Increased Asset Preloading Count

  [!NOTE] Increasing the maximum limit of preloaded assets from 100 to infinite allows games you've already played to load much faster by instantly accessing previously loaded assets.

[!IMPORTANT] For this to be effective, the game must have been fully loaded at least once, preferably with the entire map cached.

[!TIP] If a game has a "Skip Loading" button, it's recommended to use it. These games typically include a countdown timer that, after reaching zero, merely confirms that all assets are loaded.

{
"DFIntReplicatorAnimationTrackLimitPerAnimator": "-1"

Stick unanchored parts to you

[!TIP] - = up, + = down

{
"DFIntSolidFloorPercentForceApplication": "-1000",
"DFIntNonSolidFloorPercentForceApplication": "-5000"
}

Max Raycast Distance

[!NOTE] Raycasting is the use of intersection tests to solve problems in Roblox. The most common use of raycasting is to determine the first object intersected by a ray. This is done by casting a virtual ray from a certain point in a direction and determining the first surface it intersected with.

[!TIP] Break legs collision from 2 to -inf, kinda break camera on values over 3 noclip cam on 3

{
"DFIntS2PhysicsSenderRate": "-30"
}

Invisible 2

[!NOTE] Locks your character's position on the server to (0, 0, 0), having the side effect of turning you invisible. This only affects the server and other clients, not you. server-sided things that rely on your position, like clicking to get tools, will not function. In some games these can be abusable. Here is a list of them: Link

{
"DFIntGameNetPVHeaderTranslationZeroCutoffExponent": "10"
}

Invisible 3

[!NOTE] Restricts the client from sending any physics-related information. This means other people can topple you over.

Low Gravity 1

[!NOTE] 'FFlagDebugSimDefaultPrimalSolver' : True
This flag enables the new simulation engine or whatever it is.

[!CAUTION] 'DFIntDebugSimPrimalLineSearch' : 1
This setting is a poor man's gravity/flight. The default value is 100:

• Above 0: Low gravity.
• Below 1 to -1: Will make gameplay weird, especially with physics.
• Below -1: Acts as a poor man's fly mode (not really usable).

  [!WARNING] Bugginess and speed depend on the value of DFIntDebugSimPrimalWarmstartForce. Recommended values are 775 and the value I put.

[!TIP] For DFIntDebugSimPrimalWarmstartVelocity, it’s recommended to use a value of 150. However, it might be difficult to control.
