A ClearBuffer or ReportValue is a fill the GPU makes where it stands in the stream, and guest memory has its bytes once the GPU got there. A counter report reaches guest memory as a CPU write after its submission's fence, and a render condition reads the record when it is replayed. So a report followed by a clear of the same record ended as the report (in one submission always, across two when the completion thread was behind the GPU), and a condition replayed after the clear read what memory held before the fill, or the 0 of the report the clear had overwritten. A clear of at most 256 bytes into CPU-visible memory is now also applied at its place in the replay to the records it covers that a counter report went into: the covered bytes get the value in guest memory at once, reports replayed before the clear leave those bytes alone when their write comes, a condition reads them from memory, and a report replayed after the clear writes the whole record as before. The GPU's fill is recorded as before. Other small clears stay the GPU's fill alone: the GPU reads guest memory too, at once in an imported pool and through the next upload of the written page in a mirrored one, so a write ahead of it into a draw count or an atomic counter would reach passes that still want the old value. NX2NAVI_CLEAR_SMALL_CPU=0 turns it off. Whether the game clears counter records is not known. The pass timing captures of 75 scripted runs show one buffer fill a frame and nothing else about it, and the frame dump does not list buffer fills. The periodic vk_usnap line now counts the small clears, the last one's size, value and address, how many covered a record with a report, the reports into bytes cleared before, and the report writes that left cleared bytes alone. Checked with a build of the dev exe, the launcher tests, the device address table check, and a scratch link of vk_exec_xfer.c against stubs that replays reports and clears in both orders. Not run in the game. Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>
