Lock-in prevents me even co spidering Apple devices, and performance does not match what I can get elsewhere. I’m and immersive designer using Unreal Engine

It sounds like you have concerns about performance and platform lock-in when considering Apple devices for immersive design using Unreal Engine. Here are some relevant points from WWDC sessions that might address your concerns:

1. Performance on Apple Vision Pro:

   • The session Optimize your 3D assets for spatial computing discusses how the GPU workload on Apple Vision Pro scales based on the size of the app's appearance to the viewer. Immersive scenes require more optimization due to the need to render the entire view every frame.
   • The Platforms State of the Union highlights the advancements in Apple silicon and Metal, which enable console-class gaming performance on devices like the latest iPhone 15 Pro, iPads with M series chips, and Apple silicon Macs. This unified gaming platform is built with tightly integrated graphics software and scalable hardware architecture.

2. Developing for Spatial Computing:

   • The session Design great visionOS apps emphasizes the importance of using native frameworks like ARKit and RealityKit to take full advantage of device capabilities. This can help in creating high-performance and immersive applications.
   • The session Build immersive web experiences with WebXR introduces WebXR, which allows for creating virtual reality experiences that can be tested and debugged on visionOS. This could be a useful tool for developing immersive web content.

3. Optimization Techniques:

   • The session Optimize your 3D assets for spatial computing provides detailed steps on optimizing 3D content for Apple Vision Pro, including considerations for polygon count, texture memory, materials, and shaders.

4. Interactive Experiences:

   • The session Design interactive experiences for visionOS discusses design considerations for creating interactive experiences on Apple Vision Pro, which can help in telling impactful stories and connecting with the audience in new ways.

Relevant Sessions:

1. Optimize your 3D assets for spatial computing
2. Design great visionOS apps
3. Build immersive web experiences with WebXR
4. Design interactive experiences for visionOS
5. Platforms State of the Union

These sessions provide insights into how Apple is addressing performance and offering tools for immersive design, which might help alleviate some of your concerns about platform lock-in and performance.
