How To Fix Roblox FPS Unlocker Not Working:[Causes & Fixes]
How to fix the Roblox FPS Unlocker not working is a common concern for players looking to boost game responsiveness. Roblox passionate players use this tool to remove the default FPS cap of the game, which is 60.
This FPS cap can be frustrating for those who are used to playing fast games, and this tool provides a solution. However, sometimes the Roblox Frame Booster doesn’t work as expected or, worse, causes lag. In this article, we have explored three common issues players face and the solutions to fix them.
Issue-1] Roblox FPS Unlocker Not Working
If your FPS Unlocker is not working look for the following solutions one by one:
Check Compatibility Mode
The RBX unlocker may not work if it’s not compatible with your device. One attempt to fix this issue is to enable compatibility mode for the software.
- Right-click on the Roblox Frame Unlocker file.
- You will choose “Properties” from the menu.
- In the next window that opens, navigate to the “Compatibility” tab
- Select the option labeled “Run this program in compatibility mode”.
- Then click “OK” to save the changes.
Close Other Programs
Cause
When your system runs multiple demanding applications, it can slow down performance and reduce the efficiency of your Roblox Unlocker. Closing unnecessary tasks helps free up resources and improves overall gameplay.
Solution
- To do this, you have to launch the task manager by pressing Ctrl + Shift + Esc.
- In the “Processes” tab, find out the applications using high system resources.
- Right-click on each unneeded application and choose “End Task” to close them.
High Graphic Settings
Cause
High graphics settings in Roblox can cause lower frame rates, leading to lag, and you experience a less smooth game. Reducing the graphics quality can help improve FPS, making the gameplay more fluid.
Solution
- To adjust the settings, launch Roblox and start a game.
- Open the menu by pressing Escape, then click on “Settings.”
- From there, lower the graphics quality slider or turn off certain visual effects to boost your FPS.
Antivirus or Windows Defender Blocking the Unlocker
Cause
Antivirus software or Windows Defender flags the FPS unlocker as a potential threat, preventing it from running properly. This is typical behavior of antivirus software when dealing with third-party tools, especially those that modify game files or processes.
Solution
The first solution is to temporarily disable antivirus software while launching the unlocker. Then you must enable it again. But if you are still facing running issues, then add the FPS booster to the whitelist programs of the antivirus. Besides this, make sure to download FPS Unlocker from our website to prevent any risk of malware.
Issue-2] Roblox FPS Unlocker Not Launching
The first issue while downloading this FPS booster may arise during its launch. The causes behind this issue and its solutions are:
Lack of Administrator Permissions
Cause
Running RBX FPS unlocker for Windows without administrative privilege can not access necessary system resources or make the required changes to unlock frames per second rate.
Solution
- First, you will close all the tasks related to Roblox.
- Next, open File Explorer and go to the folder where Roblox FPS Unlocker is installed.
- Right-click on the executable file “rbxfpsunlocker.exe” and you will select the option of Properties in the menu.
- Scroll down to the Compatibility tab, check for “Run this program as an administrator,” click Apply, and then OK
This FPS unlocker should be started before running any Roblox game.
Outdated FPS Unlocker
Cause
The common culprit behind the FPS unlocker’s failure to launch is that it’s an outdated version. Roblox regularly updates its platform, and older versions of the unlocker may struggle to keep up with these changes.
This incompatibility issue has become especially pronounced after the Byfron update introduced by Roblox developers to combat hacking and cheating.
Solution
You can either go to the official GitHub page for Roblox Frame Unlocker’s updated version Or you can download the updated version by clicking on the link provided here on our website.
Disable Antivirus or Firewall
Cause
The antivirus prevents our system from certain hacks, exploits, or scripts. Therefore, Microsoft Defender antivirus interrupts launching or downloading the RBX FPS booster.
Solution
- You can prevent this by disabling “Real-time protection” from Windows Security.
- To do so, search for “Virus and threat protection” in the Windows search bar.
- Go to Virus and Threat Protection settings, next to Manage settings, and turn “Real-time protection” off. This temporarily disables the antivirus.
- Download RBX FPS Unlocker and check if it works.
- If it launches successfully, then re-enable your firewall or antivirus.
Issue-3] Roblox Frame Unlocker Causing Crashes, Lags, or Errors
The reasons behind the RBX FPS unlocker causing crashes or lagging may include software conflicts, device incompatibility, outdated graphics drivers, performance settings, etc. So, if your FPS unlocker is lagging, giving errors in its performance, or crashing, then check for these issues to identify the culprit.
Reinstall The Roblox FPS Unlocker
Cause
The first troubleshooting step if you are facing frequent lagging or crashes is to delete the FPS unlocker that you are currently using.
Solution
Download the latest version either from the GitHub repository or from our trusted link given here. We assure you that we are providing the updated version link here. In most cases, the issue is fixed by reinstalling the software.
Outdated Graphics Drivers
Cause
For gaming enthusiasts, your Windows drivers should be the latest and optimized. If your system has outdated or not properly optimized graphic drivers, they may not work well with the RBX booster or Roblox to raise performance issues.
Solution
- Visit the website of your trusted graphics card manufacturer (AMD, NVIDIA, or Intel).
- Open Drivers or Support section.
- Look up the most recent driver for your specific graphics card model.
- Download and install the driver by following the manufacturer’s instructions.
Check For Conflicting Software
Cause
Other applications running on your system, like screen recording software, overlays (e.g., Discord or NVIDIA GeForce Experience), or game optimizers, might conflict with the FPS unlocker, causing it not to work or create lag.
Solution
Look for any software that could interfere with the FPS unlocker, such as overlays or performance-boosting tools. Temporarily disable or remove these programs to see if there are any compatibility issues.
Unlocking FPS Too High for Your Hardware
Cause
Sometimes, by using this FPS unlocker tool, you increase FPS beyond what your hardware can support, such as setting it to 240 FPS on a weaker CPU or GPU. This causes hardware strain, and the game starts to lag or crash.
Solution
You adjust the frame per second by observing your system’s responses. If your system struggles at 240 FPS, then reduce it to 200 and check if your system is handling it well. In the same manner, set the limit to where you observe smooth system performance.
Overheating and Throttling
Cause
Unlocking FPS increases the workload on your CPU and GPU, causing them to overheat. When hardware overheats, it automatically throttles performance to cool down, and you experience system lags.
Solution
You can monitor your system’s temperature using software like HWMonitor or MSI Afterburner. Ensure your cooling system is working effectively, clean out any dust from fans, consider using a cooling pad, or reduce the game’s graphics settings to ease the load on your hardware.
Limited System Resources
Cause
Unlocking FPS increases the demand for system resources like CPU and RAM. If your system is low on resources or already overloaded by other applications, unlocking FPS may cause performance drops.
Solution
Close unnecessary programs and background tasks that consume CPU, RAM, and GPU resources. You can also adjust in-game settings to reduce the load on your system.
Power Settings Limiting Performance
Cause
If your computer is running on “Power Saver” or “Balanced” mode, it might throttle performance to save energy and you experience lagging or not working the software.
Solution
Switch to “High Performance” mode in your system’s power settings so that your PC uses its full potential for gaming, preventing performance throttling due to power-saving settings.
Corrupt Roblox Game Files
Cause
Corrupt or outdated game files can cause the FPS unlocker to malfunction or lag. This may happen if a Roblox update didn’t install properly or files were altered.
Solution
You can go for reinstalling the Roblox. Alternatively, clearing the Roblox cache or verifying the integrity of the game files can help solve this issue without a full reinstallation.
Roblox Server Issues
Cause
Occasionally, this tool doesn’t work or lags not because of the in-game settings or your system incompatibility, but because it’s due to the Roblox server. The server efficiency hits due to high traffic, and your game starts lagging.
Solution
Check community forums like the Roblox Discord to see if other players are experiencing the same issues. If it’s a problem with Roblox’s servers, just wait until it’s resolved.
FAQs
Conclusion
We’ve covered all the common issues that might cause your Roblox FPS Unlocker to stop working, lag, or crash. If you set the FPS higher than your system can handle, it may lag or crash. To optimize performance, ensure you have the latest version of the FPS Unlocker, an updated graphics driver, a high-spec system, administrative permission to run the software, and secure Roblox files.
For best results, enable compatibility mode, adjust in-game settings like reducing graphics quality, and temporarily disable antivirus software. If you still face issues, try reinstalling the unlocker, adding it to your antivirus whitelist, and checking the official Discord community to see if there’s a server issue.
