I would love to use Background GPU Access to do some video processing in the background. However the documentation of BGContinuedProcessingTaskRequest.Resources.gpu clearly states: Not all devices support background GPU use. For more information, see Performing long-running tasks on iOS and iPadOS. Is there a list available of currently released devices that do (or don't) support GPU background usage? That would help to understand what part of our user base can use this feature. (And what hardware we need to test this on as developers.) For example it seems that it isn't supported on an iPad Pro M1 with the current iOS 26 beta. The simulators also seem to not support the background GPU resource. So would be great to understand what hardware is capable of using this feature!

Hi, What's the best way to handle drastic changes in scene charateristics with the new MTLFXTemporalDenoisedScaler? Let's say a visible object of the scene radically changes its material properties. I can modify the albedo and roughness textures consequently. But I suspect the history will be corrupted. Blending visual information between the new frame and the previous ones might be a nonsense. I guess the problem should be the same when objects appear or disappear instantly. Is the upsacler manage these events for us (by lowering blending), or should we use the reactive or the denoise strength mask or something like that to handle them?

Hi there, I'm wondering if it's possible under iOS 28 developer beta to enable MetalFX scaling info with '{"MTL_HUD_ENABLED": "1" for my App. This information has been added to Mac, but looks to be absent on iPhone / iPad

Recently, I adopted MetalFX for Upscale feature. However, I have encountered a persistent build failure for the iOS Simulator with the error message, 'MetalFX is not available when building for iOS Simulator.' To address this, I modified the MetalFX.framework status to 'Optional' within Build Phases > Link Binary With Libraries, adding the linker option (-weak_framework). Despite this adjustment, the build process continues to fail. Furthermore, I observed that the MetalFX sample application provided by Apple, specifically the one found at https://developer.apple.com/documentation/metalfx/applying-temporal-antialiasing-and-upscaling-using-metalfx, also fails to build for the iOS Simulator target. Has anyone encountered this issue?

Hey all! I'm got my hands on a refurbished mac mini m1 and already diving into metal. At the moment, i'm currently studying graphics programming with opengl and got to a point where I can almost create a 3d cube. However, I noticed there aren't many tutorials for metal cpp but rather demos. One thing I love about graphic programming, is skinning/skeletal animation. At the moment, I can't find any sources or tutorials on how to load skeletal animations into metal-cpp. So, if I create my character in blender and had all types of animations all loaded into a .FBX or maybe .DAE and load this into metal api with metal-cpp, how can I go on about how this works?

Hi, trying to wrap my head around Xcode's FXPlug. I already sell Final Cut Pro titles for a company. These titles were built in motion. However, they want me to move them to an app and I'm looking for any help on how to accomplish this *What the app should do is: Allow users with an active subscription to our website the ability to access titles within FCPX and if they are not an active subscriber, for access to be denied.
