Quick answer: Vulkan pipeline cache file growing larger over months of use? Cache accumulates per-driver entries; periodically prune.
Player's cache binary is 500MB after a year; disk fills.
Prune by age
Discard entries older than 30 days. Newer entries kept.
Or size cap
Cache fixed size; LRU eviction.
Audit cache size
Per-player cache size; reports if over threshold.
“Caches grow unbounded by default. Bounds are policy.”
If your game accumulates per-player cache, the pruning policy is operational. Document.
