Included scope
Records the backend's small logical work operations into one open Vulkan command buffer and submits that buffer at the existing GPU synchronization point. This removes hundreds of per-operation command-buffer submissions while retaining command recording order and existing image barriers.
Deliberate exclusions
- Persistent staging allocation reuse and present-mode policy are isolated on separate branches.
- Present timing telemetry and the earlier
PSX_VK_*WIP diagnostics are excluded. - CRT shaders, CRT pipeline objects, screen-kind routing, and game-specific data are excluded.
