# setfpscap

Sets the game's frame-rate limit.

```luau theme={null}
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.<br />Bind F1 to toggle the cap between 60 and the player's previous setting.

      else
          savedCap = setfpscap(60)
      end
  end)

<Tip>
  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.](https://github.com/bloxstraplabs/bloxstrap/wiki/Why-you-can%27t-%28or-shouldn%27t%29-go-faster-than-240-FPS)
