CEMU 1.11.3 Adds Multi-Threaded CPU Emulation; Brings BOTW Close to Locked 60FPS

Zelda Breath Of The Wild

The CEMU development team has released CEMU 1.11.3 which adds support for multi-threaded CPU emulation alongside other optimizations.

The new version of the popular Wii U PC emulator is available now to all Patreon members and is slated for a public release next week. It appears that the version of the emulator significantly improves dual and triple core FPS over single-core CPU’s, and it basically allows for a framerate close to a locked 60FPS.
