GLSLtoSPV takes an optional SPIRVCache, keyed on a 32-bit hash of the source, stage and variant, plus the source length. A changed shader simply misses. thin3d's shaders and the other fixed ones use a global cache in PSP/SYSTEM/CACHE/vulkan_spirv.cache, loaded on first use and saved after graphics init, when a game's cache is saved, and at shutdown; it's flushed once it reaches 32 entries, about twice what a session compiles, so outdated ones don't pile up. Game shaders keep theirs in the .vkshadercache, ahead of the shader IDs so that the compiles on load find it (version 60), and only what the session used is saved. A cold glslang costs about 40ms before its first shader here, and 0.3-0.9ms per shader after that. Co-Authored-By: Claude Opus 5.5 (1M context) <[email protected]>
