Understanding Roblox’s FPS Cap

Roblox typically caps frame rates at 60 FPS by default, but you can push beyond this limit using several methods. The most popular approach involves third-party FPS unlockers, while Roblox Studio offers built-in options for developers.

Method 1: Using Roblox FPS Unlocker

The most widely-used solution is the Roblox FPS Unlocker by axstin, available on GitHub. This tool modifies Roblox’s frame rate limiter without altering game files:

  • Download the latest version from the official GitHub repository
  • Extract the files and run RFU.exe as administrator
  • The tool runs in the background and automatically unlocks FPS when Roblox launches
  • Your frame rate will now match your monitor’s refresh rate (144Hz, 240Hz, etc.)

Safety note: This FPS unlocker is generally considered safe by the community and doesn’t violate Roblox’s terms of service, as it doesn’t provide gameplay advantages.

Method 2: Roblox Studio Settings

For developers working in Roblox Studio, you can unlock FPS through built-in settings:

  1. Open Roblox Studio
  2. Go to File → Studio Settings
  3. Navigate to Rendering → Performance
  4. Set “Graphics Mode” to Manual
  5. Adjust “Graphics Quality” to your preference
  6. Look for frame rate options and disable the 60 FPS cap

Alternative Methods

Some players report success with:

  • Graphics driver settings: Force higher refresh rates through NVIDIA Control Panel or AMD Software
  • Windows settings: Ensure your display is set to its maximum refresh rate in Windows display settings
  • In-game graphics: Lowering Roblox graphics quality can help achieve higher frame rates on lower-end hardware

Important Considerations

Before unlocking your FPS, keep these factors in mind:

  • Hardware requirements: Your GPU and CPU must be capable of rendering above 60 FPS
  • Monitor refresh rate: You need a high-refresh monitor (120Hz, 144Hz, 240Hz) to see the difference
  • Game optimization: Not all Roblox games are optimized for high frame rates
  • Battery life: Higher FPS consumes more power on laptops

Troubleshooting Common Issues

If you’re not seeing improved performance:

  • Check that your monitor is actually set to a high refresh rate
  • Verify the FPS unlocker is running (check system tray)
  • Lower in-game graphics settings if your hardware is struggling
  • Close unnecessary background applications
  • Update your graphics drivers

Once you’ve optimized your Roblox experience with higher frame rates, you’ll want to explore games that truly showcase the smoother gameplay.

Who this is for: Roblox players and developers wanting smoother gameplay with higher frame rates above the default 60 FPS cap.
