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 supported, PECI level control has the highest priority and will override both Core and Package level controls, however you won’t find PECI controller on most system (PECI Support: No), so you probably don’t have to worry about it. PECI: represents an individual controller to control p-state hints. If this doesn't appear, or you have problems using Vulkan, read the OpenGL Optimization Guide Intel Speed Shift feature support multiple levels of control Core, Package and PECI.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.
What happens in stuttering is the game freezes for microseconds (or fraction of second), skipping the next frame, and this ruins the whole gaming experience.
Vulkan also allows us to use a new experimental VSync technique which allows Cemu to use the game's built-in frame-pacing instead. Game Stuttering is a very common problem that can be faced by anyone, even if you have a high-end PC with a powerful graphics card, processor, tons of RAM, and equipped with all the latest gaming hardware. 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. For the best performance, we'll be switching the default graphics API from OpenGL to Vulkan.
