 This preserves the game's own timing and lets the host Vulkan presenter display
 the movie without trying to execute the PS5-specific Bink GPU decode path.
 
-Without an adapter, Bink files remain visible to the guest and the game's
-statically linked decoder runs normally. Set SHARPEMU_BINK_MODE=skip only when
-explicitly testing a title whose cinematics are optional.
+Without an adapter, Bink movies are skipped by default: their open call returns
+not-found so games that mark cinematics as optional progress to their next
+state instead of waiting on an empty Bink GPU texture.
 
 Set SHARPEMU_BINK_MODE=dummy to retain the open and show a built-in,
 non-decoded placeholder frame. This requires no SDK, but is a visual diagnostic
