A frame limit only paced what reached the screen: a game without vsync
kept drawing hundreds of frames a second that were thrown away (AIO at
a 60 fps limit drew 155 to 2,446 fps), so the limit saved no power.
With Performance mode on and a frame limit set, the session now sets
gamescope's per-game limit over gamescope_control (gamescopectl
debug_set_fps_limit). gamescope's limiter then has its WSI layer hold
Vulkan games, DXVK and VKD3D included, to the limit. gamescope's own
--framerate-limit option is reset on its first frame in 3.16.29, and
Steam resets the per-game limit while it starts, so the session watches
gamescope's limiter state file and sets the limit again whenever it is
off (a once-a-second check with shell builtins, no process started).
With Performance mode off, a limit paces the screen only, as before.
The session also gives gamescope a fixed limiter state file path, so
gamescope stops leaving a new one behind on every start, and removes
the old ones.
Device-proven on the AYANEO Pocket FIT (Turnip, AIO D3D11, 45 s runs on
battery, three runs each): at a 60 fps limit the game held exactly
60.0 fps and the device drew 7.08 W instead of 9.45 W, with 1.3 instead
of 2.6 busy cores and 5 instead of 11 % GPU load. No limit: unchanged.
Once Blizzard's Agent has removed a game it answers GET /game/<uid> with
an empty object, not installed false, so a finished uninstall read as a
failure and opened Battle.net.
A cancelled install now waits for its Agent job to end before the
uninstall runs, and removes the folder only once the Agent no longer
lists the game or the folder is empty. Uninstall gives up when Battle.net
or a game keeps the prefix busy for a minute, so the page falls back to
opening Battle.net. An uninstall only counts when the Agent reports the
game as not installed.
Battle.net games now install like Epic, Xbox and itch games: Install,
pick a location, and the download runs in the Downloads tab while the
Stores page stays open. droiddeck-battlenet starts Blizzard's own Agent
on its own under a headless gamescope and drives its local API, so no
window opens and nothing waits on the Battle.net client.
- Progress, speed and time left come from the Agent, with pause, resume
(the Agent keeps what it downloaded) and cancel, which uninstalls the
partial game and removes its folder.
- A job only finishes once the Agent has really run it and the game is
playable; the first status after a request can still describe the
previous operation.
- Installed games check Blizzard's version service and show Update when
the build on disk is behind; the update repairs missing files too.
- Battle.net games can be uninstalled from their page through the Agent.
- Games land in the chosen location: internal storage, other storage or
a Games folder.
- The hero keeps its action row clear of the playtime column.
Steam games and Battle.net started from the KDE desktop run on the GPU in gamescope, opened as a KDE window, and Plasma no longer leaves programs with a zero realtime CPU limit that got games killed.
The flow solver starts at flowFinest_, but its images, uniform buffers and descriptor sets were allocated for every pyramid level. Keep the seven-level indices and allocate flow resources only where the solver reads and writes them.
The default preset avoids three unused RGBA16F images, saving 38,707,200 bytes of pixel payload at 2560x1440 without changing the shaders or recorded GPU work. Add native allocation/dispatch regressions and document the resource budgets.
* fix: Reuse the prefix the client made for a shortcut id
droiddeck-proton-run builds the prefix path as steamapps/compatdata/<appid>,
but the client names that folder with the signed 32-bit form of the shortcut
id. A shortcut whose id has the top bit set therefore got a second, empty
prefix, and the first launch after that ran wineboot from scratch: the
session sat on a black screen for the length of a full prefix init, and the
old prefix was never reused.
Match the folder by its unsigned value instead, the way the client does:
int(name) % 2 ** 32 == appid % 2 ** 32. prefix_of() also accepts a negative
folder name now, and reports its unsigned id so the Steam environment it sets
up stays valid.
* fix: Reject folder names int() cannot read, and skip files
lstrip("-").isdigit() accepts "--1" and superscript digits, which int() then
raises on, and one such entry in compatdata would stop shortcut resolution.
Match r"-?[0-9]+" instead. A matching name is also only used when it is a
directory, so a stray file cannot take STEAM_COMPAT_DATA_PATH.
* fix: reuse signed shortcut compatdata prefix
* fix: prefer initialized Proton shortcut prefixes

Adds a Performance mode switch under Mode settings > Frame rate, off by default and stored per mode like the frame limit. Off keeps today's behaviour. On:
- with no frame limit, the compositor hands buffers back to the game as soon as they are replaced instead of once per refresh, and gamescope's WSI layer is asked for at least 8 swapchain images; a chosen frame limit still paces
- DROIDDECK_WSI_BYPASS_CHECK_MS=100 lets gamescope's WSI layer reuse its present-time Xwayland bypass check (patch 0117, gamescope-3.16.29-p13); WINE_OFFSCREEN_CHECK_MS=100 does the same for winex11 once a DroidDeck-Proton release carries that fix. Off sets both to 0.
The gamescope pack now ships the patched WSI layer and SessionFiles stages it over the runtime's stock copy. Two per-game options, off by default: PROTON_DXVK_D3D8 and WINE_D3D_CONFIG renderer=vulkan|gl.
AIO Graphics Test on an AYANEO Pocket FIT (Adreno 750), off -> on: Vulkan 204 -> 1787, OpenGL 296 -> 2169, D3D12 308 -> 3563, D3D11 1133 -> 2874, D3D9 1253 -> 3098 fps; DiRT Showdown 92.2 -> 93.4 (GPU-bound).
* feat: adjustable RAM and VRAM caps for the container
Performance > Memory gets two sliders:
- RAM cap (soft, Steam sessions): when the session is resident above the
cap, the session watcher compresses the Steam client into zRAM, waits for
its page-out acknowledgment, then compresses the rest of the session
(processes that loaded libblsession) if still over. Nothing is closed.
Measured at most every 30 s; the client is read back once usage drops
below the cap. Invalid values leave the cap off. Needs zRAM swap.
- VRAM cap: sets dxgi.maxDeviceMemory ahead of the game's own DXVK_CONFIG,
so Direct3D games budget for less video memory. A game profile still
wins. Applies from the next session.
* fix: back off the RAM cap when paging out cannot get under it
A cap below the game's working set was never met, so the watcher paged out
the client and the whole session every 30 s for the rest of the session.
Usage is still measured every 30 s, but after a page-out that leaves the
session over the cap the next one waits twice as long (60 s up to 10 min),
resetting once usage is under the cap. The client step is skipped while the
client is already under 512 MB resident.
* fix: RAM cap covers desktop Steam, signals each group once, no idle churn
- Steam opened from the desktop runs the same session watcher, so the cap
is exported whenever the Steam client runs, not only in Steam mode.
- The second page-out goes to the rest of the session only; Steam was
signalled again even when its own step had been skipped as already small.
- A cap page-out while no game runs stays paged out. Reading the client back
right away pushed it over the cap again and repeated every minute; only a
game closing while over the cap still defers a read-back.
* fix: RAM cap marks the client packed only when it compressed it
When the cap skipped the client as already small during a game, it still
recorded the client as packed, so the regular in-game client page-out
waited up to 300 s for a page-out that never happened.

GE-based Protons, the default with the x86-64 Steam client, run umu-protonfixes. Its Black Ops III fix switches the prefix to Wine's ALSA driver, which has no device here and replaces DirectAudio, and its Dark Souls Remastered fix runs the VC++ 2017 installer, which fails under ARM64 Proton.
Xbox Cloud Gaming: stream from the store and Games tab, native player with DroidDeck frame generation
Stream Xbox games with Xbox Cloud Gaming (Game Pass) from DroidDeck, outside
the Linux session.
- Backend: `xodus-cli cloud-token` (tools/xbox/droiddeck-cloud-token.patch)
gets the streaming tokens; they stay in memory.
- Web player (default): the Greenlight player page (tools/xcloud-player, MIT)
in a WebView, plus Microsoft's own xbox.com/play player. In-stream menu with
screen effects (sharpen, colour, deband, FXAA, CRT, NTSC, Toon, fps cap),
stream quality, performance overlay (level, layout, top right / top left)
and rumble.
- Native player (opt-in, Android 10+, Player engine: Native): Google's WebRTC
(io.github.webrtc-sdk 125.6422.07, BSD) with the Greenlight protocol ported
to Kotlin, in its own process (:xcloudnative) with its own instance of
DroidDeck's compositor. Decoded frames reach the compositor as
AHardwareBuffers (new stream mode, VK_ANDROID_external_memory_android_
hardware_buffer import), so DDFG 2x and LSFG 2x/3x/4x run on them. Live
frame generation, frame-rate target (presets and a 10-165 fps slider, even
pacing), zero-copy picture, small network buffer, fast decoder, instant
controller input, overlay with engine and on-screen fps, background end,
restart and web fallback. It takes the main process's tokens through
XboxCloudTokenService; they are fetched ahead while a cloud game is shown.
- The compositor requests the dma-buf import extensions only where the driver
has them (the system driver has none).
- Catalog: cloud availability, Game Pass plan CFQ7TTC0K6L8 counted, library
filter All / Owned / Game Pass / Cloud, Stream and Add to Games on the store
page, stream-only Games-tab entries (Stream + Download / Play + Stream).
- Xbox games get VC++ 2015-2022 and the ARM64 runtime registry entries
(vcredist2022_arm64, built in until the catalog has it) before each launch.
- Controller focus reaches pickers opened from a game page (install location,
uninstall); Add / Remove from Games keep the focus.

On some phones (tester: Honor BKQ-N49, Android 17) Xbox sign-in stopped with
"the Xbox helper stopped with exit code 1" before Microsoft's page opened.
The backend asks the app to read and save credentials over a socket and waits
10 s for each reply. The app sealed credentials with a StrongBox-backed
Keystore key, and each StrongBox operation took 7-15 s on that phone, so the
backend gave up. The app still finished those saves afterwards, leaving a
record without a username that every later attempt had to read back slowly.
- Seal new store credentials with a TEE Keystore key (v2 envelopes); v1
envelopes still open with the old key and move to v2 on their next write.
- A sign-in discards an Xbox record without a username (an unfinished
sign-in) before starting the backend.
- The backend waits 30 s for the app's credential reply.
- The backend names the failing step instead of only credential-io (socket
connect/exchange, session lock, missing socket name/port/key), and falls
back to a keyed 127.0.0.1 port when the abstract socket is refused.
- The app's credential listener logs and retries accept errors, serves each
connection on its own thread, and logs slow requests with per-stage times.

Steam's ARM64 client has no desktop-portal file chooser, so
SteamClient.System.OpenFileDialog failed at once and every Browse button
(Add a Non-Steam Game, shortcut target, library folder) did nothing.
The Steam UI bridge now answers it with a GTK file chooser run under
Steam's reaper, so gamescope shows it over Steam.
droiddeck-steam-shortcuts and AddedGames.accountConfig took the account
marked "MostRecent" in loginusers.vdf, else the only userdata folder.
The arm64 client here writes no MostRecent, so with two accounts in one
install nothing was picked: no added or store game reached
shortcuts.vdf ("no signed-in account yet; nothing written") and Steam
answered their launch with "App configuration unavailable".
Without MostRecent, take the account marked AutoLogin, then the one with
the latest timestamp. Both sides use the same order so the app reads the
config the guest script writes.
Steam installs Proton EasyAntiCheat Runtime (1826330) and Proton BattlEye Runtime (1161040) as tool depots. The launcher's Games tab and the desktop's game entries now skip them like the other runtimes.
The manifest's arguments apply only when its build matches the installed version, only arguments the merge inserted are tracked as its own, escaped quotes split like a Windows command line, and the REDprelauncher rule needs Cyberpunk2077.exe beside it.
Feature level 12_2 makes vkd3d-proton report mesh shaders and ray tracing that Turnip doesn't provide. Caravan SandWitch (Unreal Engine 5) then builds mesh shader pipelines without a pipeline layout and the driver crashes; Cyberpunk 2077 stops at ray tracing initialization. Only these two games get 12_1, and a value set in a game's own settings still wins.
