CEMU Version 1.18.2 offers huge improvements in the Vulkan API by greatly decreasing the amount of shader stutters.

For the latest version of the popular Wii U emulator, the CEMU team has significantly improved the speed at which shaders can be compiled, which might also slightly reduce GPU load. The downside, however, is that shader loading screen is much slower. The CEMU team writes that they will address this in a future update.

# Cemu detailed changelog for 1.18.2

# Patreon release date: 2020-04-24

# Public release date:  2020-05-01

  • general: When updating graphic packs Cemu will let the user know if previously enabled graphic packs were removed or renamed
  • general: Improved robustness of account.dat parser (invalid files could crash Cemu on launch)
  • general: Updated language files
  • coreinit: Added API MEMFreeToFrmHeap (#322)
    • Used by Marvel Avengers: Battle for Earth (but other issues still prevent it from running
  • nn_nfp: Changed behavior of GetNfpRegisterInfo for unregistered Amiibos
    Games that expect Amiibos with a registered owner no longer should display an empty ErrEula message box
  • nn_nfp: Implemented API GetErrorCode and NFCGetTagInfo
  • Vulkan: Correctly emulate depth clamping
    This fixes the overly bright backgrounds in some stages of Super Smash Bros for Wii U
  • Vulkan: Added an overlay notification for when a Vulkan graphics pipeline has to be compiled
  • Vulkan: Added experimental SPIR-V optimization pass which is applied to all shaders that are compiled during the shader loading screen.
    • This should reduce pipeline compilation stutter if a shader cache is present. It may also reduce GPU load slightly. The downside is that the shader loading screen is much slower. But we plan to address this in a future Cemu update.
  •         By default this option is disabled. It can be enabled under Debug -> Experimental
  •         Also note that this option results in different shaders being generated and consequently also triggers new pipeline compilation
  • input: Remember ip and port for DSU client

The latest version of the Wii U emulator is available now for Patrons and will be released publically tomorrow.
