How to Unlock FPS in Roblox (120+ FPS Easily)

Roblox, a platform that has taken the gaming world by storm, often comes with a standard 60 FPS cap. But what if you have a high-refresh-rate monitor and want to make the most of it? In this guide, we’ll walk you through two methods to unlock the FPS cap in Roblox.

Method 1: Removing the FPS Cap Using FFlag

Step 1: Locate Roblox Files

First, navigate to where your Roblox files are stored. Typically, you’ll find them in:

  • C:/Program Files (x86)/Roblox/Versions
  • C:/Users/{your user}/AppData/Local/Roblox/Versions

Step 2: Find RobloxPlayerBeta

Search through each folder starting with “version” until you stumble upon RobloxPlayerBeta. This is where we’ll be unlocking the framerate for our client.

Step 3: Create a ClientSettings Folder

Once inside the version folder, create a new folder and name it ClientSettings.

Step 4: Download or Create ClientAppSettings.json

You can either download the ClientAppSettings.json file or, if you’re wary of downloading, manually create this file in the ClientSettings folder. Add the following FFlag:

{"DFIntTaskSchedulerTargetFps": 144}

Adjust the value to match your monitor’s refresh rate. For instance, if you have a 120hz monitor, set the value to 120.

Step 5: Launch a Roblox Game

Fire up a Roblox game, and voilà! Your FPS should now soar above 60.

Note: This method is confirmed to work at the time of writing this guide.

Method 2: Using Software to Unlock FPS

Step 1: Visit the rbxfpsunlocker GitHub Page

Head over to the rbxfpsunlocker GitHub page to get started.

Step 2: Download the Software

Download the latest version of rbxfpsunlocker.

Caution: Chrome might flag rbxfpsunlocker as a potential threat since it modifies running Roblox processes to unlock the framerate. However, rest assured, it doesn’t inject anything, making it safe and non-bannable.

Step 3: Extract and Run

Once downloaded, extract the folder and run rbxfpsunlocker.exe. If done correctly, you should notice a change in your FPS.

Remember: Unlocking FPS doesn’t boost it; it merely removes the cap. Ensure your computer can handle more than 60 FPS in Roblox.
