DeepSea Render Metal provides the Metal implementation of the renderer.
If you wish to get optimal performance for Apple silicon, you may want to consider supporting fragment inputs. This requires a separate set of shaders and render passes, but can reduce memory bandwidth and improve overall performance. It is roughly equivalent to using render subpasses on Vulkan, though is unfortunately requires a significantly different interface to utilize. It's also advisable to use dsRenderbuffer rather than dsTexture for any buffers you don't need to use outside of the render pass, which can reduce the amount of memory the driver needs to allocate. You may check the hasFragmentInputs member of dsRenderer to determine whether you should load the fragment input render passes and shaders or subpass versions.
