Lacking strong macOS/Metal support: potentially enables macOS users to be able to run these projects natively for the first timeįortunately, we quickly found two projects which matched our criteria: RPCS3 and Dolphin.

Already using Vulkan for rendering: allows us to simply load gfx-portability on macOS in place of a Vulkan driver on other platforms, because gfx-portability implements vulkan.h.

Open-source: allows us to easily debug issues and add or modify existing macOS window and surface support.

We were especially interested in finding projects matching the following criteria: Expanding Portability TestingĪfter improving functionality and performance of gfx-portability’s Metal backend through benchmarking Dota2, and verifying certain functionality through the Vulkan Conformance Test Suite (CTS), we decided to expand our testing to other projects. This post is focused on the Metal backend only. We are also building a Vulkan Portability implementation ( gfx-portability) based on it, which allows non-Rust applications using Vulkan to run everywhere. It’s a single Rust API with multiple backends that implement it: Direct3D 12/11, Metal, Vulkan, and even OpenGL. Gfx-rs is a Rust project aiming to make graphics programming more accessible and portable, focusing on exposing a universal Vulkan-like API.
