This repository contains a list of games compatible with the Cemu Metal backend. You can see the list by going to Issues (games that run perfectly will be under the Closed tab). If you don't find the game you were looking for, it means it wasn't tested yet.
You can get the latest release of Cemu Metal here (pick the top-most one). From there just run any game you'd like (also make sure you have Metal selected as a graphics API in settings).
If you have tested a game that isn't in Issues, please report it here. Use the game name as a title. If the game you tested doesn't work as intended, please provide a detailed description of what exactly the issue is. Attaching a log is really helpful as well.
If there are graphical issues in the game, it might be useful if you made a frame capture. See this guide on how to make one.
There are some tricks to improve performance for some games. Turning Accurate Barriers off in the Debug section of the menu bar can greatly improve the performance in The Legend of Zelda: Breath of the Wild (make sure to also use the FPS++ mod). Setting the buffer cache mode (in game profile) to either device shared or host will slightly improve the performance in most games, and will also completely fix performance issues present in The Legend of Zelda: Wind Waker HD in areas with lots of particles. Just note that changing this option might cause graphical issues in certain games (for example in New Super Mario Bros U, all blocks will appear yellow when going into the same level twice).
