The old 60 FPS-unlock tutorial is outdated for most Windows players: Roblox now has an official Maximum Framerate setting. Open Roblox Settings and choose a supported limit—60, 120, 144 or 240 FPS—or leave it on Default. Raising the cap does not make your computer render faster; you need hardware that can produce the frames and a display with a sufficiently high refresh rate.

Change Roblox’s frame-rate cap in Settings

  1. Open the Roblox app and launch an experience.
  2. Open the in-game menu and select Settings.
  3. Find Maximum Framerate and choose the highest available value you actually need: 60, 120, 144 or 240 FPS. Default is also available and corresponds to 60 FPS.
  4. Return to the experience and check the displayed frame rate with Shift+F5.

Roblox introduced this control for Windows PCs with displays above 60Hz. The official options and recommendation to use the in-game setting are in Roblox’s Maximum Framerate announcement. Roblox’s Creator Hub documentation likewise says Windows users can raise the client cap from its 60 FPS default up to 240 FPS.

What a higher cap does—and does not do

The setting raises the maximum rate Roblox is allowed to target; it does not add CPU or GPU capacity. Your computer still has to render each frame, and your display must refresh fast enough for you to see the additional frames. Roblox says that if your device cannot reach the selected value, you should not notice a difference. The original tutorial made the same core distinction: unlocking the cap is not an FPS boost.

  • For a 60Hz display: choosing a value above 60 does not make the display show more than 60 refreshes per second.
  • For a high-refresh display: a higher setting can allow Roblox to use the display’s capability, provided the computer can render at that rate.
  • If performance remains below the selected cap: the cap is not the bottleneck; raising it further will not create the missing frames.

How to check FPS and diagnose performance

Press Shift+F5 in the Roblox client to show the debug statistics summary, which includes frame-rate information. To investigate performance, Roblox recommends using manual graphics mode and checking client statistics; Studio measurements can be skewed and should not be treated as a reliable substitute for client performance.

How the current setting compares with the old methods

Method Roblox support Maximum selectable rate Requirements and update behavior
Maximum Framerate setting Official Windows client setting, announced May 30, 2024 240 FPS Choose the rate in Roblox Settings; no file edit or third-party unlocker is needed.
ClientAppSettings.json edit Legacy community workaround, not the current recommended method Not stated in the original tutorial’s cited guidance Edits can stop working after Roblox client updates and may need repeating, according to forum replies.
rbxfpsunlocker utility Third-party workaround; Roblox recommends using its setting instead Not stated in the original tutorial’s cited guidance Requires external software. Roblox says unlockers modify an internal dynamic flag that was not intended as a stable public API.

The 2023 community tutorial described both a JSON edit using DFIntTaskSchedulerTargetFps and the third-party rbxfpsunlocker utility. Roblox’s 2024 announcement explains why its own setting is preferable: external unlockers rely on an internal flag that Roblox does not provide as a stable public interface. Forum responses to the original topic also note that the file workaround may break following client updates, and the topic was later marked outdated.

Should you still use the JSON method or an unlocker?

For the common Windows use case, use Roblox’s built-in control. The legacy approaches are historical workarounds, not a more capable route to higher performance. The available evidence for the old tutorial does not establish current macOS support, a current maximum rate for either workaround, or that either method will continue working after updates. Avoid relying on them when the supported in-game option covers the need.
