Vulkan: unbacked sparse images for textures too large to back
Title 1 samples an 8192x8192, 12-level, 68-layer array (a sparse virtual
texture, ~23 GB): vkCreateImage failed and Eden aborted, or VMA put it in
system memory and staged a full upload (34 GB private). Images over 2^28
texels are now created sparse-resident with no memory bound; the texture
cache neither uploads nor downloads them. Images merely over the VRAM
budget are allocated without the budget limit instead of failing.
