Roblox FPS Unlocker | rbxfpsunlocker

Roblox FPS Unlocker or rbxfpsunlocker is a tool designed to disable the default frame limiter and V-sync in Roblox, which are typically set to cap the game at 60 frames per second (FPS). This limitation can lead to performance issues, particularly on more powerful PCs capable of higher frame rates. By disabling these settings, Roblox FPS Unlocker allows your game to run at higher FPS, potentially improving gameplay smoothness, reducing input lag, and enabling you to take full advantage of high-refresh-rate monitors.

Roblox FPS Unlocker works by disabling the frame limiter and V-Sync settings within Roblox. This allows your game to exceed the default 60 FPS limit, potentially providing a smoother gaming experience. It injects codes into Roblox to automatically turn off these limitations, allowing your system to achieve higher FPS based on its capabilities.

All detections are false positives. Internally, RbxFPSUnlocker "tampers" with running Roblox processes in order to uncap framerate and can appear as suspicious to an anti-virus. For reasons unbeknownst to me, 32-bit builds of RFU garner many more false positive detection's than 64-bit builds and are no longer included in new releases.

If you don't trust me, feel free to download the repository, review the source code, and compile the project yourself with Visual Studio 2019.

Otherwise, add an exception to your anti-virus for rbxfpsunlocker.exe (or the folder it is in).

To check your FPS in Roblox, you can simply press Shift + F5 during gameplay. This will display various performance stats, including the current FPS.

Try entering fullscreen using Alt+Enter or by going to settings "Fullscreen Mode - On".

I say with great emphasis, as this seems to be a common misconception, that Roblox FPS Unlocker is an FPS unlocker and not a booster. It will not boost Roblox's performance in any way and only removes Roblox's 60 FPS limit. To take advantage of Rbxfpsunlocker, a computer powerful enough to run Roblox at more than 60 FPS is required.

This being said, if you know your computer is powerful enough but still aren't seeing higher frame rates with the FPS unlocker, feel free to submit an issue.

You can create your own list of FPS cap values by editing the FPSCapValues array inside the settings file located in the same folder as rbxfpsunlocker.exe.

Simply right click the settings file and open with notepad. See below highlighted section where you need to insert manually FPS rate!

RbxFPSUnlocker does not install itself anywhere. It can be deleted by simply exiting the program if it is open (tray icon->Exit) and deleting rbxfpsunlocker.exe.
