This experimental setting allows extra cores to be utilized for PPC CPU emulation instead of 1, however not many games actually utilize multiple PPC cores and currently causes stability issues/crashes or offers no benefit for most titles. See the Recommended Settings section for what is recommended under CPU Options / Affinity. I wouldn't recommend going under a score of ( 1,800 ) if you plan to play Breath of the Wild at 1080p 30FPS (Native Wii U Framerate)

This list ranks CPUs for Single Thread IPC: You can check out Darkemaster's AMD FX Compatibility Video list for Cemu 1.12.0 and for 1.15.3~1.15.8 Single Thread IPC and Overclocking are the most important factors for how well CEMU will perform on your PC! Additionally, Dual-Core or Triple-Core Recompiler options should allow better performance in the few applicable games that support it, especially Breath of the Wild.Generally speaking (for Breath of the Wild and almost any CPU), it's recommended to be over your base clock speed where possible for better performance (overclocking.).It is suggested AMD CPU users keep better quality RAM installed (DDR4 3200Mhz recommended,) using more than 1 RAM stick, as emulators are particularly RAM intensive. Any CPU will work, technically, but non-Ryzen AMD CPUs typically lack Single-Thread processing power non-Ryzen AMD CPUs may struggle heavily with more demanding Wii U titles.
