For Dolphin, we previously focused on visual correctness.
Previously, we benchmarked Dota2 and were able to run many other applications and engines successfully, including Dolphin Emulator. This post is focused on the Metal backend only. We are also building a Vulkan Portability implementation 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.
