Achieve smoother gameplay by unlocking the FPS cap in Roblox with the RBX FPS Unlocker.

Roblox FPS Unlocker is a free software that helps the user to unlock the FPS. Roblox limits the default frame rate to 60 FPS, which can be frustrating. Download Roblox FPS Unlocker to enhance your gaming experience today.

Roblox FPS Unlocker is the best free tool to remove the default 60 FPS cap in Roblox. 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 Roblox 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

Roblox FPS Unlocker is not an official app by Roblox devs despite that it is a trustworthy software. RBX FPS Unlocker is safe and free of viruses.

RBX FPS Unlocker modifies the running Roblox processes to disable the frame rate limiter and unlock the FPS. For this reason, anti-viruses may pick it up as a virus but that is just a false alarm. You also won’t be banned from playing Roblox using this app.

Roblox FPS Unlocker FAQs

What is FPS Unlocker

Roblox FPS Unlocker software removes the default FPS limit (60) in Roblox. 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 Roblox terms and conditions given by Roblox developers 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 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The FPS Unlocker not working issue is generally caused by an outdated FPS Unlocker version.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 Roblox has received an update but you haven’t updated Roblox FPS Unlocker yet. To fix this error, download and install the latest Roblox FPS Unlocker version.

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

Try entering fullscreen by pressing Alt+Enter. Since Roblox 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 it again that Roblox FPS Unlocker 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 custom framerate cap?

You can create your custom list of FPS caps 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 due to a lack of internet access to Roblox FPS Unlocker 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 Roblox. 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 Roblox Studio, the Windows store app, and 32-bit client. Enables the Flags File method for Roblox's new 64-bit client.
    2. Memory Write: RFU's traditional unlocking method. It works by scanning and writing to the memory of running Roblox processes to unlock FPS. Roblox's 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 exist.
    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.
