Cemu needs three things people skip: the graphics packs, the correct input profile and a shader cache that is allowed to build. Get those and it runs smoothly.
Point Cemu at your **game folder**, enable the **graphics packs per game**, map the **controller** once as a profile and let the **shader cache** build on the first run.
Cemu reads games from a folder structure, not from a single file. Add the root folder in the settings and let it scan; titles appear with their real names once the metadata loads.
Options > General settings > Game pathsEach game has its own set of packs: resolution, frame rate, shadow quality and fixes for known glitches. Enable them per game, not globally, and read the notes attached to each one.
Right-click the game > Graphic packsMap the input once, save it as a named profile and apply it to every game. Remapping per title is how a library ends up with five different layouts.
Options > Input settings > Controller 1The first minutes in a new area stutter because shaders are compiled on demand. Play through the opening area once and the stutter stops; the cache is stored next to the emulator.
Vulkan is the right default on modern GPUs. Leave vsync off if you use a variable refresh display; the emulator's frame pacing behaves better without a hard cap.
Options > Graphic settings > APICemu's audio can lag behind the picture on some titles. If sound drifts, switch to the other backend and test the same scene instead of adjusting the buffer blindly.
The folder layout is wrong or the metadata has not downloaded. Rescan the path and check that each game sits in its own folder.
Shader compilation. Play the area once and let the cache grow; it is normal on a first run.
The profile is not applied, or the wrong controller slot is active. Check Input settings per game.
Disable the pack. Some titles tie logic to the frame rate and cannot be fixed from the emulator side.
Cemu installs the shared system files itself. Game files are separate and come from your own console.
Only if you generated it yourself. Prebuilt caches from the internet mix in data you do not own.
Delete the Cemu folder; every setting and cache lives inside it. Game files stay where they are.
