Cemu 1.27.1 ((install)) Online

The "Accurate barriers" option for the Vulkan API is now enabled by default. While users can still disable it for a slight performance boost, keeping it on eliminates most flickering graphics and rendering artifacts.

Cemu 1.27.1 was one of the final versions released under the "Experimental" 1.x branch before the project officially went open source on GitHub with the release of Cemu 2.0. It represented a period of massive internal refactoring, including a migration to CMake and an upgrade to C++20, which paved the way for the Linux and eventually Android versions of Cemu .

The decoder now supports multiple parallel sessions, which specifically fixed a long-standing issue where menu videos in Mario Tennis: Ultra Smash would freeze or crash the emulator.
