Roblox FPS Unlocker is a free software that helps the user to unlock the FPS. By default, the game limits the default frame rate to 60 FPS, which can be frustrating.

The main job of this program is to remove the default 60 FPS cap set by the game. Players can also set a custom FPS as high as their hardware supports, making the game feel more responsive and reducing the input lag. It is entirely legal and safe to use FPS Unlocker, and you will not get banned for it.

Note: RBXFPSUNLOCKER does not boost FPS if you’re running the game below 60 FPS on a low-end PC. Rather it simply removes the framerate cap which only high-end PCs can utilize.

Is Roblox FPS Unlocker Safe

Although it is not an official Roblox app, it is still a very trustworthy software used by millions of players.

This FPS Unlocker modifies the game’s running processes to disable the frame rate limiter and unlock the FPS. For this reason, anti-viruses may flag this as a malicious file but that is just a false alarm. Rest assured the game will not ban you from using this app.

It is also not available for Android mobile devices but players can use the Arceus X app instead to unlock FPS without running a script. Chrome browser (extension) version of the game and Chromebooks aren’t supported either.

What is an FPS Unlocker?

It is a tool that removes the default FPS limit (60) in the game. You can also set higher framerate caps like 75, 90, 120, 144, 360, and so on, depending upon your monitor’s supported refresh rate.

Is FPS Unlocker Roblox Safe?

Yes, the software is safe to install and use, also it does not violate any official terms and conditions that could result in a ban.
As of 2019, it’s no longer a bannable offense. You can install these FPS Unlockers without the fear of being banned for using software like these.

How to fix the Roblox FPS Unlocker not working?

The FPS Unlocker not working issue is generally caused by an outdated FPS Unlocker version. We recommend upgrading your FPS Unlocker application to the latest available version.

How to fix Roblox FPS Unlocker’s unable to find Task Scheduler?

This error usually occurs when the game has received an update but you haven’t updated the FPS Unlocker yet. To fix this error, download and install the latest version of RBX FPS Unlocker.

How do I resolve choppiness and input lag at high framerates?

Try entering fullscreen by pressing Alt+Enter. Since this game wasn’t designed to run at high framerates, these problems can occur when you unlock the FPS cap.

I used the FPS unlocker but my FPS are still dropping below 60.

We’re emphasizing again that it is not an FPS booster software. It will only unlock the framerate cap on devices that are capable enough to reach higher FPS.

Can I set a manual framerate cap?

Yes, you can create a list of FPS caps manually by modifying the FPSCapValues inside the Settings file located in the same folder as rbxfpsunlocker.exe.

Why do I get a “Failed to connect to Github” error?

This problem happens when RBX FPS Unlocker can’t access the internet to check for updates. It can however be safely ignored by pressing OK.

Why do I get a “Variable scan failed” error?

This error occurs due to another conflicting app. Maybe you’re running an exploit or a script that is already modifying the FPS values of the game. Shut those conflicting apps down and hopefully the problem will be fixed.

Roblox FPS Unlocker Latest Version 5.0 Update

  • Added support for Roblox's new Hyperion-protected 64-bit client
  • Added an Unlock Method setting with 3 options:
    1. Hybrid (Default): Enables the Memory Write method for Rbx Studio, the Windows store app, and 32-bit client. Enables the Flags File method for the games new 64-bit client.
    2. Memory Write: RFU's traditional unlocking method. It works by scanning and writing to the memory of running the game's processes to unlock FPS. The new anti-cheat makes this method more annoying, but it is still feasible. WARNING: USE THIS METHOD AT YOUR OWN RISK WITH THE NEW 64-BIT CLIENT. While I've taken a few measures to make this option behave nicely with Hyperion, risk of detection and errors still exists.
    3. Flags File: Sets the DFIntTaskSchedulerTargetFps flag in <roblox_version_path>/ClientSettings/ClientAppSettings.json. This method is completely noninvasive at the expense of being unable to change the cap while the game is running. Thanks to Raspy_Pi and pizzaboxer for telling me about it.
