Cemu v1.21.2 is released. Cemu is a Nintendo Wii U emulator that runs commercial games. Highly experimental software to emulate Wii U applications on PC.

Cemu Changelog:
CPU/JIT: Added support for instructions STHUX and RLWIMI.
Provides a minor performance boost in games that utilize these instructions (e.g. Sonic Boom)

Vulkan/OpenGL: Added support for integer texture samplers
Project Zero seems to be the only game that uses these but no obvious visual difference was observed

Vulkan: Compilation of shader modules now uses multiple threads
This gives a small speed boost for synchronous compilation since vertex and pixel shaders for a drawcall can compile in parallel
It also gives a speed boost to asychronous compilation due to using extra threads
Vulkan: Fixed a rare race condition where asynchronous shader compilation could fail and lead to permanent graphic bugs for the current play session
Vulkan: Added barrier before frame output which should resolve black pixel artifacts on some GPUs
Vulkan: Fixed a bug that could cause device loss during swapchain creation
