setfpscap - Mintlify Starter Kit

Sets the game’s frame-rate limit.

setfpscap(fps: number): number

Most often used to bypass Roblox’s built-in fps settings restrictions. Common pattern: drop to 30 on alt accounts or autofarm scripts. Frees CPU and GPU headroom for the active client.

Parameters

Parameter	Type	Description
`fps`	`number`	The new cap, floored to an integer.

Returns

number - the cap that was active before calling setfpscap().

Aliases

setfps

Example

In Roblox, wallhops land more reliably at 60 fps.
Bind F1 to toggle the cap between 60 and the player’s previous setting.

Roblox caps actual rendering at ~240 Hz from 2024 onwards. Caps above that store and read back fine, but the rendered frame interval won’t drop below ~4 ms. Background here.
