[!CAUTION] FastFlags are super powerful. Messing with them without knowing what you’re doing can break things, cause crashes, or make Roblox behave weirdly. So be careful. only change them if you really know what you're doing or you’re following trusted instructions.

FastFlags are hidden settings used by Roblox to test out new features before they’re fully released. They let Roblox turn certain things on or off like updates, changes, or other behind-the-scenes improvements without needing to update the whole app.

These flags help developers experiment with changes or slowly roll out new features to a small group of users first. If something goes wrong, they can easily disable the flag without causing problems for everyone.

There are different types of FastFlags:

• FFlag – simple on/off switch

• FInt – a number value

• FFloat – a decimal number

• FString – a text setting

Chevstrap makes it way easier to work with FastFlags, especially on Android. It gives you a simple interface to view, edit, and apply FastFlags safely. It’s a handy tool for advanced users.

Let's take a look at presets!

Framerate limit

Framerate limit on Android games is kind of like setting a speed cap for how fast your game updates the screen. Say it’s set to 60 FPS. that means your game won’t show more than 60 frames every second, even if your android could handle more.
