This feature is experimental and may cause issuesĬemu should now be running the fastest it can, with a huge increase in performance for some users.If you use a display with variable refresh rate (G-SYNC), set this to Off instead.Set 'VSync' to Match emulated display (Experimental).Ensure that your 'Graphics Device' is set to use your most powerful GPU if your device has dual graphics.If this doesn't appear, or you have problems using Vulkan, read the OpenGL Optimization Guide.Change the 'Graphics API' to Vulkan if it is not already.Click Options -> General settings on the top bar.If your GPU doesn't support Vulkan, follow the OpenGL Guide. Ensure you are running the latest drivers and that your GPU supports Vulkan. This avoids tearing and reduces input latency compared to previous methods. Vulkan also allows us to use a new experimental VSync technique which allows Cemu to use the game's built-in frame-pacing instead. More recent builds can do this in under 1/10th of a second, depending on the CPU. After these shaders have been recompiled and cached, they won't need to be converted again, so the graphical glitches stop.Īsynchronous shader compilation in an older, slower Cemu version. The video below shows loading Breath of the Wild for the first time using asynchronous shader complation. This means that when the shader is first called, it skips being rendered to the screen, and is instead stored for the next time it's used, providing a much smoother experience. This can take some time, which causes small stutters in the game every time a new one is sent to the emulator.ĭoing this asynchronously allows the emulator to run the process in the background. When running games in Cemu, graphical shaders need to be re-compiled to work on a desktop GPU. While less stable, Vulkan tends to run faster and has extra features in Cemu which OpenGL doesn't. Hardware: Minimum of Intel Core i3 2.5Ghz or AMD Phenom II 2.6Ghz with 4 GB RAM Intel HD Graphics 4000 / Nvidia GeForce 710 / AMD Radeon HD 6450 or better screen resolution of 1280x768 or higher We'll try to resolve this issue as soon as possible. For the best performance, we'll be switching the default graphics API from OpenGL to Vulkan.
