Metal 3 introduces the MetalFX upscaling framework, which renders complex scenes in less time per frame with high-performance upscaling and anti-aliasing, mesh shaders support.
Metal is designed for macOS and especially optimized for Apple Silicon. However, due to a bug or misconfiguration, some Macs — including recent M1–M4 models — are showing a false warning that they do not support Metal.
Metal is the technology that powers hardware-accelerated graphics on Apple platforms.
Metal Performance On Apple hardware, Metal offers remarkable performance, especially with unified memory on Apple Silicon. Because Apple controls the entire hardware and software stack, the optimizations can be extremely efficient.
