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)

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.

Graphical Settings

Move Pre-Render Phase [~25% Performance Boost]

Important

This FastFlag moves the Pre-Render task to an off thread after all other tasks are completed. By default, Pre-Render runs first, forcing the render thread to wait until the Pre-Render process finishes before it can start rendering a frame.

Note

With this FastFlag enabled, Pre-Renderer is executed while the main thread is processing the previous frame. This adjustment allows the main thread to proceed without waiting for Pre-Renderer, leading to increased framerates at the expense of some frame latency.

Tip

This flag is most effective in CPU-bound scenarios.

Caution

Enabling this FastFlag may lead to compatibility issues with certain games. (It works fine dw)

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"

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.
