The details line read "Update 1.4.3"; it now reads "Game 1.4.3 · Recomp 0.3.7". The port version drops its +commit suffix there, the art's hover text keeps the full one. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

+
+        - The log of the run that crashed is `logs\totk.log` in the folder of `totk.exe` (F1, Advanced tab, Open log folder). Copy it before you start the game again: the next start renames it to `totk.1.log`, and after five starts it is gone.
+        - Attach the whole file. Do not cut or edit it: the crash report is at the end, the GPU and driver lines are at the start.
+        - The log says `device lost` or `VK_ERROR_DEVICE_LOST` and the GPU is an NVIDIA one: set GPU pass marks to On (F1, Advanced tab, Diagnostics), restart the game, make it crash again and attach that log. The `vk: pass marks` lines then name what the GPU was drawing.

+        ### Recording the log
+
+        1. In the settings menu (F1), Advanced tab, Diagnostics: turn on Performance log. For freezes and hitches, also turn on Flight recorder. Restart the game: both take effect at the next start.
+        2. Play at least three minutes in the place where it happens. The log gets a frame-time summary every 60 s, and a line for every frame over 50 ms that names what the frame waited for.
+        3. With the flight recorder on, press F8 right after a hitch. It also saves on its own after every frame longer than the freeze threshold (100 ms), at most once per 10 s.
+        4. Close the game with Quit game in the menu or the window's close button. Do not end it from Task Manager: the last summary is written when the game exits.
+        5. Copy `logs\totk.log` from the folder of `totk.exe` before you start the game again.
+        6. Each flight recorder save is a folder; the log line `flight: dump` names it. Zip the folders and attach them.
+        7. Turn both off again afterwards: they cost a little frame time.

+        ### What to attach for your area
+
+        Close the game with Quit game in the menu or the window's close button, then copy `logs\totk.log` from the folder of `totk.exe` before you start the game again.
+
+        **Audio.** Open `totk.ini` in the folder of `totk.exe` and add the line `trace = audio`; when the file already has `trace = perf` (Performance log on), change it to `trace = perf,audio`. Start the game, play at least two minutes where the sound goes wrong and close the game. The log then has an `audio:` line every 5 s with the buffer underruns. Name the output device and how it is connected (speakers, headphones, USB, Bluetooth, HDMI), and attach a short video with sound if you can. Remove the line afterwards.
+
+        **Controls and input.** Name the controller and how it is connected (USB, Bluetooth, Steam Input). Does it also happen with keyboard and mouse?
+
+        **Controls, game logic, anything you can trigger again.** Turn on Input recording (F1, Advanced tab, Diagnostics), restart the game, load a save, make the bug happen and close the game. Attach `input-record.txt` from the logs folder and a zip of the save you loaded: the `profile` folder next to `totk.exe`. The recording replays what you did, so we can see the bug on our machine.
+
+        **Installer.** Attach the newest `install-*.log` from `temp\logs` in the folder of `TotK-Setup.exe` (on Linux: `.setup-temp/logs` in the install folder), and the log file the error message names.

 - NVN front end from MacNativeGames (`nvn_api_*.c`, `nvn_obj.h`, texture layout and deswizzle). The game records command buffers through it; nothing reaches the GPU until the game submits.
 - Vulkan 1.3 back end in place of MacNativeGames' Metal one. At `QueueSubmitCommands` the recorded NVN commands are replayed into Vulkan command buffers (`vk_exec*.c`).
 - Memory pools. Apple's unified memory let MacNativeGames use the game's pools zero-copy. The back end imports the pools as host memory (`VK_EXT_external_memory_host`). On a discrete GPU, pools bound as buffers are mirrored in device-local memory and the pages the CPU wrote (write watch, above) are uploaded before a replay; idle pool regions are made read-only so the write-watch queries skip them (`vk_memory.c`). GPU-rendered textures are written back when the CPU reads them: on a pool invalidate, on a CPU copy, and for small targets once the CPU waits for a fence (`vk_texture.c`).
- Replay thread. `TOTK_REPLAY_ASYNC=1` moves the replay off the submitting thread onto a queue at most one frame behind the game; reads of GPU results wait for the newest writer instead of draining the queue (`vk_backend.c`). It is off by default because no timing has shown a gain yet.
+- Replay thread. `TOTK_REPLAY_ASYNC=1` moves the replay off the submitting thread onto a queue at most one frame behind the game; reads of GPU results wait for the newest writer instead of draining the queue (`vk_backend.c`). It is on by default: where the game waits for the GPU it overlaps the replay with the game threads (a GTX 1650 in the Depths, issue #88), elsewhere it is neutral; it adds up to a frame of latency, and `replay_async = 0` turns it off.
 - Recorder thread. The Vulkan calls the replay makes into its command buffer are made by a thread of their own (`vk_rec.c`, after Savage Wind Recomp and LAS Recomp): each `vkCmd*` copies its arguments into a packet of a ring and the recorder makes the calls in order; calls into other command buffers are made at once; the recorder also ends the command buffer, and the submit waits until it has. In the town on an RX 9070 the replay takes 17% less time on the submitting thread. It is off by default on AMD GPUs, where the driver loses the device or hangs the GPU at startup with it (`TOTK_VK_RECORDER=1` forces it on, `=0` makes every call on the submitting thread).

+// itself when the process ends and the pipe closes, so there is no shutdown path. Every answer frame is read and
+// discarded: unread, they would fill the pipe's buffer and block the client's writes.

+// c7 pair 0x100 apart, c5 pairs their rounded size apart, the pair's contents the same object moved a little). The
+// copy this frame does not write still holds last frame's when the frame is submitted, so the uniform snapshot

+// Motion-vector survey (TOTK_MV_SURVEY=1, off by default): measures whether per-object motion vectors can be made from
+// the uniform blocks the scene's draws bind. Per-object vectors need each object's matrices of the previous frame; the
+// game keeps none (its shaders read gsys_shape, gsys_skeleton and gsys_projection of this frame only), so they would
+// have to be kept from the previous frame's uniform snapshot (vk_usnap.c). That works when a block's guest address
+// stands for the same object from one frame to the next, which this survey measures.
+//
+// For every scene draw (vertex stage, scene depth bound: D32 at least DLAA_SCENE_MIN_W wide, as vk_dlaa_draw), each user bank
+// (c3 + index) with a binding is noted: address, size and its first SNAP bytes as of the submit (the snapshot's copy).
+// At each frame the bank's blocks are compared with the previous frame's and the one before:
+//   repeat1 / repeat2   blocks whose address was bound in that bank one / two frames ago
+//   same / near / far   of the blocks repeated from last frame: bytes unchanged / every float within 5 % or 1.0 of
+//                       last frame's (the same object, moved a little) / some float further (another object, likely)
+// The game writes its per-object blocks into two copies that take turns, so a moving object's block is at one address
+// in even frames and another in odd ones. To find the rule that pairs them, a bank's blocks bound two frames ago but
+// not last frame (this frame's copy) are sorted by address, and so are last frame's blocks not bound this frame (the
+// other copy); with equal counts they are paired in order:
+//   pairs, delta        the paired blocks and the commonest address differences (this frame's minus last frame's)
+//   psame / pnear / pfar the pairs' contents, as same / near / far above (near: the same object, moved)
+//   unequal             frames whose two lists had different lengths (no pairing that frame)
+// What the bank holds: each block's leading 3x4 matrices (rows of a rotation times a scale: three rows of the same
+// length, at right angles, finite), counted over the whole block as of the submit:
+//   mats 0 / 1 / 2-7 / 8+   blocks by that count (one: an object's place, gsys_shape; many: bones, gsys_skeleton)
+// Every SURVEY_FRAMES frames the log gets two lines per bank with the window's totals:

+"""Writes runtime/vk_mvobj_fs.h: the SPIR-V of the per-object motion fragment shader (vk_mvobj.c), assembled here

+
+    #version 450

+The vector is last frame's window position minus this frame's, in render pixels, as runtime/shaders/dlaa_mv.comp
+writes it. Its descriptor set and binding are renumbered by vk_pipeline.c like a translated shader's (the .res.json

+"""Unpack an NSZ or XCZ (a game file compressed by the nsz tool) into a plain NSP.
+
+An NSZ is an NSP whose NCAs are stored as NCZ files: the first 0x4000 bytes of the NCA (its encrypted header) as they
+are, then an NCZSECTN table of the NCA's sections with the AES-CTR key and counter of each, then the rest of the NCA
+decrypted and compressed with zstd, either as one stream or as an NCZBLOCK table of independently compressed blocks.
+An XCZ is an XCI whose secure partition holds NCZ files. Unpacking encrypts the sections again, so every NCA comes back
+byte for byte; its file name is the first half of its SHA-256, which is checked. The output is an NSP of the secure
+partition (an XCZ) or of the NSZ's files, with .ncz renamed to .nca. Format: nicoboss/nsz, nsz/NszDecompressor.py
+(__decompressNcz) and nsz/BlockDecompressorReader.py; this is our own code.
