# Cemu detailed changelog for 1.18.2c # Patreon release date: 2020-04-24 # Public release date: 2020-05-01 # New in 1.18.2c: Vulkan: Fixed a bug in the new cache which could lead to Cemu freezing or crashing randomly # New in 1.18.2b: Vulkan: The SPIR-V optimization pass is now always enabled (no longer considered experimental) Vulkan: Added SPIR-V cache to speed up shader loading screen on subsequent runs Vulkan: Fixed an issue where the wrong image layout (LAYOUT_UNDEFINED) would be provided for operations on 3D textures On strict or optimized drivers this could lead to texture data being thrown away (as far as we know, only Nvidia 445.75+ drivers are affected) # New in 1.18.2: 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 triggers new pipeline compilation input: Remember ip and port for DSU client Note: (#xx) refers to bug tracker issues resolved by this change.
