Returning to the CPU flushed all queued drawing, also when a list only reached its stall address. Wipeout Pure builds its lists as it goes and stalls about a hundred times a frame, so the main thread spent a third of its time finishing the drawing at those flushes. A stalled list isn't done, so now only a finished one flushes there, which makes Wipeout Pure 15% faster. What relied on that flush now flushes itself: memory copies, sets, readbacks and uploads that overlap the queued drawing, and save states, before memory is saved or loaded (FlushPendingDrawing). Syncs and the display already did. Queued drawing still reads textures from PSP memory when it runs, so a game that rewrites a texture between stalls without syncing would see the new one; on hardware the GE has usually drawn with the old one by then.
