Fix SPIR-V Shader Compilation Failure & Vulkan Opcode Mismatch
When AnyPS5 translates PS5 GCN/RDNA bytecode to SPIR-V intermediate representation, missing Vulkan 1.3 extensions (such as VK_KHR_shader_float16_int8 or VK_KHR_dynamic_rendering) on the host GPU can trigger an immediate abort with "VK_ERROR_INITIALIZATION_FAILED" or "Invalid SPIR-V instruction".
AnyPS5 bypasses classic emulation by directly mapping PS5 shader stages to Vulkan compute and raster pipelines. If your host GPU driver is outdated or lacks modern Vulkan extensions, the translation pipeline fails.

Verify Vulkan 1.3 Driver Support on Host GPU
Run vulkaninfo in PowerShell or terminal to confirm your graphics driver supports Vulkan API version 1.3.0 or higher. For NVIDIA, update to driver >= 535.xx; for AMD, update to Adrenalin >= 24.x.
vulkaninfo | Select-String "apiVersion"Enable Shader Cache Staging Directory
Ensure the game directory has an existing ./shader_cache folder with write permissions. This allows AnyPS5 to cache compiled SPIR-V bytecode and eliminate runtime stutter.
mkdir ./shader_cacheLaunch with Fallback Vulkan Extensions Disabled
If using an older GPU (like GTX 1050 Ti or Intel UHD 620), pass fallback flags to disable optional ray tracing and hardware haptics.

Does AnyPS5 support DirectX 12 instead of Vulkan?
No. AnyPS5 upstream compiles strictly against the Vulkan API for cross-platform compatibility across Windows and Linux. Any site offering "AnyPS5 DirectX 12 Edition" is distributing fake trojan malware.
