Roblox has a built-in 60 FPS cap that limits how smooth the game looks regardless of how powerful your PC is. For players with capable hardware, this cap is an artificial ceiling that leaves performance on the table. Bloxstrap’s FPS unlocker removes this restriction and lets Roblox run at whatever frame rate your system can actually produce.
Why Does Roblox Have a 60 FPS Cap?
Roblox originally implemented the 60 FPS cap for several reasons. First, it was designed to keep the game accessible on a wide range of hardware by setting a consistent performance target. Second, Roblox’s game physics and certain gameplay systems were originally tied to frame rate in ways that made higher FPS problematic.
Over the years, Roblox has decoupled many of its systems from frame rate, making higher FPS more viable. The cap remained in place largely for legacy reasons and as a conservative default. Third-party tools like standalone FPS unlockers and now Bloxstrap’s built-in version have been removing this cap for years with no significant issues for the vast majority of players.
How Does the Bloxstrap FPS Unlocker Work?
The Bloxstrap FPS unlocker works by setting a specific internal Roblox FastFlag called DFIntTaskSchedulerTargetFps to a value higher than 60. By default, this flag is set internally to 60, which enforces the frame rate cap. Changing it to 240 or another high value tells Roblox’s scheduler to allow frames to be rendered at a much higher rate.
Bloxstrap handles this flag change automatically through the FPS unlocker toggle, so you do not need to know the technical details to use it. Simply enabling the option in Bloxstrap’s settings applies the flag change at every Roblox launch without any further input from you.
For players who want more control over the exact target FPS value, the FastFlags editor in Bloxstrap allows you to set any specific value you want. Our guide at Bloxstrap FastFlags Explained: What They Are and How to Use Them Safely explains how to use the editor manually.
Does the FPS Unlocker Still Work in 2026?
Yes, the Bloxstrap FPS unlocker is fully functional in 2026 as of the time this article was written. Roblox has made several engine updates over the past few years, but the underlying FastFlag mechanism for frame rate control remains in place and continues to work correctly with Bloxstrap’s implementation.
Occasionally after a major Roblox engine update, the FPS unlocker may temporarily stop working if Roblox changes the relevant flag name or behavior. In these cases, the Bloxstrap development team typically pushes an update within a short time to restore functionality. Keeping Bloxstrap up to date, which it does automatically by default, ensures you always have the latest working implementation.
How to Enable the FPS Unlocker in Bloxstrap
Step 1: Open Bloxstrap Settings
Right-click the Bloxstrap icon in your system tray and select “Open Bloxstrap,” or launch it from your Start menu or desktop shortcut.
Step 2: Navigate to the Fast Flags Tab
Click on the “Fast Flags” tab inside the Bloxstrap window. This is where all FastFlag controls live, including the FPS-related settings.
Step 3: Enable the FPS Unlocker
Look for the FPS Unlocker option or preset within the Fast Flags section. In recent versions of Bloxstrap, there is a convenient preset or toggle that handles the frame rate unlock with a single click. Enable it and set your desired target FPS if prompted.
Common target values to choose:
- 144: Matches a 144Hz monitor refresh rate
- 165: Matches common 165Hz gaming monitors
- 240: The popular choice for competitive play on high-refresh-rate displays
Step 4: Save and Restart Roblox
Save your settings in Bloxstrap, then fully close Roblox if it is running. Relaunch it through Bloxstrap. The FPS unlocker is now active and will apply automatically at every subsequent launch.
How to Verify the FPS Unlocker Is Working
After enabling the unlocker and joining a Roblox game, press Shift + F5 or Shift + F3 to open the Roblox performance stats overlay. This shows real-time FPS data. If the FPS unlocker is working, you should see your frame count exceed 60 FPS in situations where the game would previously have been capped.
Note that the actual FPS you see depends on your hardware. If your GPU and CPU can only produce 80 FPS in a given game, the unlocker will not magically produce 240 FPS. It simply removes the artificial cap so your hardware can operate at its actual ceiling.
What FPS Can You Expect?
This depends entirely on your PC’s hardware. Here is a general guide:
- Integrated graphics (Intel/AMD): May still struggle to exceed 60 FPS consistently in demanding games even with the cap removed
- Budget dedicated GPU (GTX 1050 / RX 560 equivalent): 80 to 120 FPS in most Roblox games
- Mid-range GPU (RTX 3060 / RX 6600 equivalent): 144 to 240+ FPS in most Roblox games
- High-end GPU (RTX 4080 / RX 7900 equivalent): 240+ FPS in virtually all Roblox games

Does a Higher FPS Actually Help in Roblox?
Yes, in several meaningful ways:
Smoother Visual Experience
Higher FPS means smoother animations and less visual judder. Even if you cannot consciously count frame rate differences, your brain perceives smoother motion and responds to it more easily.
More Responsive Controls
Higher frame rates reduce input lag, which is the time between pressing a key and seeing the result on screen. In fast-paced Roblox games, lower input lag translates to more responsive aiming, movement, and reactions.
Better Use of High-Refresh-Rate Monitors
If you have a 144Hz or higher monitor and Roblox is capped at 60 FPS, you are not using your monitor to its potential. Unlocking FPS lets you take full advantage of a high-refresh-rate display.
Is the FPS Unlocker Safe to Use?
The Bloxstrap FPS unlocker has been used by millions of Roblox players for years. There are no known cases of accounts being banned or penalized solely for using it. The feature works through a legitimate FastFlag mechanism within Roblox’s own engine and does not inject any code into the Roblox process.

Troubleshooting the FPS Unlocker
FPS Still Shows 60 After Enabling
Confirm that you fully closed and relaunched Roblox after saving the Bloxstrap setting. FastFlag changes only take effect at Roblox startup, not mid-session. Also verify Bloxstrap is up to date since a Roblox update may have required a Bloxstrap fix.
FPS Is Higher Than 60 but Still Feels Choppy
This is usually a monitor issue rather than an FPS issue. Make sure your monitor’s refresh rate is set to its maximum value in Windows Display Settings. A monitor set to 60Hz will display 60 frames per second regardless of how many the game produces.
Game Becomes Unstable at High FPS
Some older or poorly optimized Roblox games can have minor physics or visual quirks at very high frame rates. Try setting your FPS target to 144 instead of 240. This usually resolves stability issues while still delivering a noticeable improvement over 60 FPS.
Final Thoughts
The Bloxstrap FPS unlocker is one of the most straightforward and highest-impact features in the entire application. Enabling it takes under a minute and the benefit is immediately noticeable if your hardware can produce frames above 60 FPS.
Combined with the right FastFlags from our list at Best Bloxstrap FastFlags for FPS Boost in 2026 (Working List), low-ping servers from the Bloxstrap Server Region Checker, and the full feature suite covered in Bloxstrap Apps: Every Built-In Feature Explained for Beginners, you will have one of the most optimized Roblox setups possible in 2026.
