Cemu allows you to use multiple cores for it's emulation. Since the Wii U had a total of three CPU cores it'll only allow you to use up to three CPU cores/threads from your CPU. You can set this amount by changing the CPU Mode setting.


Changing your CPU Mode

Where to find this setting

You can change the CPU Mode in a game profile. This can simply be done by right-clicking the game you want to change and click the Edit game profile option. There you'll find the Mode option under the CPU section.

What should I use

First of all, it's important that the game is compatible with the multi-core recompilers. You can test this yourself by trying to play the game for an extended amount of time. If you're experiencing crashes or softlocks you should go back to using the singlecore-recompiler! There's also a list of games at the end of this page with a list of games that have been tested.

Secondly, you want to check if you'll benefit from using the dualcore-recompiler or triplecore-recompilers over the singlecore-recompiler. You'll need to know the amount of cores and threads your CPU has. If you don't know how many cores or threads your CPU has, Google your CPU model's specification page. Here's the recommended settings for your CPU:

CPU Cores CPU Threads CPU Mode
2 2 Singlecore-Recompiler
2 4 Singlecore-Recompiler or Dualcore-recompiler (close any background processes!)
4 4 Dualcore-Recompiler
4 8 Dualcore-Recompiler or Triplecore-Recompiler (close any background processes!)
6+ 6+ Triplecore-Recompiler
