StorageTextureBudget gave the storage image cache a quarter of the VK_EXT_memory_budget budget of the largest device-local heap (capped at TextureCacheBudget, never below 512 MiB) whatever else the heap held, while SampledTextureBudget takes what that budget leaves after the heap's other use. On a 10 GB card the storage cache kept 2024-2170 MiB into a level load whose depth and render target allocations then failed with VK_ERROR_OUT_OF_DEVICE_MEMORY with the heap at its reported budget where a run logged it. The storage image budget is now what the reported budget leaves after the heap's use other than the cached storage images, the unused part of the sampled textures' 2 GiB floor and an eighth of the budget; the caps at a quarter of the budget and at TextureCacheBudget and the 512 MiB floor stay. The sampled budget still reserves TextureCacheBudget for the storage cache, at least the storage cap, and the storage budget reserves the sampled textures alive, so neither counts bytes the other may take; while the sampled textures alive stay within their floor the sampled budget falls first, then the storage budget, and above it both fall together. The budget line also prints when the storage image budget moves by more than a tenth, with its previous value, and StorageTextureCacheBudget is exported for the execution test.
