     - `single_queue` - Do not use asynchronous compute or transfer queues.
-    - `upload_hvv` - Attempt to use host-visible VRAM (large/resizable BAR) for the UPLOAD heap. May improve performance at the cost of using additional video memory over system memory.

+      May free up vital VRAM in certain critical situations, at cost of lower GPU performance.
+      A fraction of VRAM is reserved for resizable BAR allocations either way,
+      so it should not be a real issue even on lower VRAM cards.
