MetalHudLoader lets jailbreakers see live GPU information in Metal-based apps

Have you ever wanted to be able to gauge your handset’s GPU performance? Apart from developing a keen eye for jitteriness, you’d be hard-pressed to find a good method on the iPhone; until now, that is.

MetalHudLoader UI.

Enter MetalHudLoader, a new and free jailbreak tweak by iOS developer pookjw that, as shown in the screenshot example above, puts a graphics overview heads-up display over the top of any Metal-enabled app that you might be using.

As you can see for yourself, MetalHudLoader displays a wide array of GPU-centric information, including the following:

  • The type of GPU you’re using
  • The current display resolution
  • The current display frames per second
  • The amount of graphics memory available
  • And more…

MetalHudLoader is designed to launch automatically whenever a compatible Metal-based app is opened. If you don’t see the interface upon launching an app, then the most likely reason is that the app isn’t Metal-driven.

For those unaware, Metal is an API that apps can use to communicate with the graphics hardware embedded on any of Apple’s mobile chipsets.

MetalHudLoader isn’t really practical for most people since it only gets in the way of the viewing experience, but if you’re ever interested in checking out your graphics performance in a particular app, then it may come in handy.

MetalHudLoader is available as a free download from the developer’s GitHub page, where it’s open source. Upon downloading it, users can install it with a package manager app such as Sileo or Zebra. The tweak is fully compatible with jailbroken iOS & iPadOS 15 and 16 devices, but unfortunately doesn’t work with rootless jailbreaks. There are no options to configure.
