Just as scheduled, a new Cemu update has dropped and can now be downloaded by the public. This new version of the Wii U emulator, 1.22.12, adds some important fixes and new speedups. There's been a fix for those experiencing crashes in the Vulkan--the new default API as of last month--settings, and some tweaks have been made so that certain loading screens in Fatal Frame 5 will no longer crash the emulator. Also notable for this build is an improvement for Vulkan where both the async shader and pipeline compilation are multi-threaded. This means that visual pop-in won't be as prevalent or last as long, and that background compilations will be sped up. Grab the latest version over at the official website, below.

# Cemu detailed changelog for 1.22.12b
# Patreon release date: 2021-04-30
# Public release date: 2021-05-07

# New in 1.22.12c:

Vulkan: Fixed regression introduced with 1.22.12b that caused broken graphics on some GPUs/drivers

# New in 1.22.12b:

general/Vulkan: Fixed a crash that could occur when opening the general settings window
input: Fixed an issue where WGI would not show up in the input APIs

# New in 1.22.12:

Vulkan: Async shader and pipeline compilation is now multi-threaded
This speeds up background compilation and shortens the duration of missing visuals

mmu: Emulate the scratch memory region at the end of the address space (0xFFFFFFE0 - 0xFFFFFFFF)
Fixes a crash that would occur during some loading screens in Fatal Frame 5 (#347)

input: Fixed an issue where WGI (Windows.Gaming.Input) would sometimes cause Cemu to not close properly
input: Generally improved robustness of WGI
input: Improved performance when using GC controller API (#513)

gfxPacks: Added a new option to rules.txt:
default=true
If specified, the graphic pack will be enabled by default
This is intended to be used for workaround packs when there are no side-effects

logging: There is now a logging option to toggle log output for coreinit logging (OSReport, OSConsoleWrite and similar)

Note:
(#xx) refers to resolved bug tracker issues. See http://bugs.cemu.info/projects/cemu/

[Ampersound]

At this point, it’s much better to use Vulkan than OpenGL even with Nvidia.
The 1080ti will support async shaders. Just make sure you’re on the latest drivers.

I’d only suggest using OpenGL on Cemu for the few games that are completely broken with Vulkan

For example
If you tried BOTW on both backends, I guarantee you’d have a better time on Vulkan

I've tried both as well, and Vulkan gave me 10+ more fps in Hateno Village.
I was using a GTX 750.
