Build real-time neural rendering pipelines with Metal

A Podkey summary of Build real-time neural rendering pipelines with Metal, from WWDC 2026.This week’s theme is Apple’s graphics stack getting a lot more comfortable with neural tricks, and doing it in ways that feel practical instead of sci-fi demo only. The big ideas are a very usable MetalFX denoising path for live viewports, a handful of details that make or break image stability, and a broader push toward tiny neural networks running right inside shaders. And when you zoom out, the through line is pretty clear: Apple silicon is making real-time rendering, denoising, tone mapping, and even on-the-fly training start to live in the same neighborhood.MetalFX denoising for live viewportsThe albedo channel really mattersTransparency and where not to denoiseMotion vectors and temporal stabilityNeural tone mapping in one passTiny neural nets inside shadersPer-frame training for changing lightWhy the hardware side mattersThis podcast was created with Podkey.
