Metal provides a platform-optimized, low-overhead API for developing the latest 3D pro applications and amazing games using a rich shading language with tighter integration between graphics and compute programs. To help you do more while managing ever more complex shader code, Metal adds an unparalleled suite of advanced GPU debugging tools to help you realize the full potential of your graphics code.
To better realize the latest GPU rendering techniques, you can now call dynamic libraries, use function pointers, and leverage the Ray Tracing API directly from your graphics shaders.
Efficiently combine precompiled functions into more complex functions at run time. This allows shader authoring tools to precompile individual shader nodes while maintaining flexibility as they author shaders.
The Ray Tracing API now supports motion blur, user instance IDs, and an extension of numerical limits to help you generate immensely complex scenes with professional renders.
MPSGraph adds new operations and optimizations using Metal buffer-based ML primitives on the GPU, so you can accelerate ML model training on Mac with higher peak performance.
The new Metal backend in PyTorch version 1.12 enables high-performance, GPU-accelerated training using MPS Graph and the Metal Performance Shaders primitives.
The TensorFlow-Metal PluggableDevice adds improvements to machine learning training with new operations accelerated on GPU, custom operations, and distributed training support.
Optimize your graphics code for power and performance on all Apple platforms.
To help achieve peak performance with the latest rendering techniques, Metal Debugger now includes performance counters and bottleneck analysis tools while providing a unified view of Metal commands, resources, and buffers on the timeline of GPU events.
To dramatically reduce the time it takes to debug incredibly large GPU shader code, Xcode 13 now includes the option to target and debug specific functions within the overall GPU shader code.
Xcode 13 can automatically find difficult bugs, such as buffer overruns, in complex GPU shader code.
To simplify optimizing game texture assets for Apple platforms, the new Texture Converter Tool supports the latest modern texture formats used by high-end games. For game developers with a Windows-based build environment, the Texture Converter Tool is also available in the Metal Tools for Windows package.
