Store EFB Copies to Texture Only must be enabledĪs with Dota2, gfx’s Metal backend was tested in 2 modes: one with Immediate command recording and one with Deferred.The Dolphin settings used for the benchmark were: We ensure the game window is on screen and in focus while being benchmarked. proposed a simple benchmark scenario: run the game Metroid Prime 2 (US), load into Sanctuary Fortress, wait for the animation to finish, and finally record 20 seconds of frame times (without providing any input to the game). After games appeared to render correctly, we shifted our focus to performance to ensure they also render quickly. 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.
