* feat(lsfg): take Lossless Scaling from Steam by itself, import it once owned, rebuild on update - Lossless.kt owns the DLL and its shader cache. The copy the Steam client installs (runtime library or the card's) is taken by itself and taken again when the client updates it (size/mtime stamp). The DLL is copied in and built into a cache named after its SHA-256, so a new DLL hands the compositor a new path; a build that fails keeps the working cache. Builds are serialized. - The Steam session asks the signed-in client once per session whether the account owns app 993090 until the answer is yes, then records it and the app stops asking (BL_LOSSLESS_OWNED). Once owned, the frame generation menu offers "Import Lossless.dll…", on the main screen and in the session drawer; an import stays until Steam's copy changes. - The compositor restarts the LSFG engine when its cache path changes, and a new engine selection clears an earlier start failure, so an updated DLL or a retry no longer needs the app restarted. - The HUD says when LSFG is waiting on Lossless Scaling instead of "starting"; frame generation strings are resources. - Removed LsfgNative's unused DLL variant and cache-match calls. * Find Lossless.dll in added Games libraries too * LSFG: 120, 90 and 60 fps targets alongside 2x-4x The pacer's target-rate mode picks 0-3 generations per game frame. While it is warm the input ring and shared chain follow every frame, so frames that generate nothing don't leave the next one without history. * Credit LSFG: Camille LaVey / Eden, ported to WinNative and DroidDeck by @maxjivi05 * LSFG: aim 0.1 fps under the target so output never passes the refresh rate

DroidDeck brings the SteamOS experience to Android: Valve's Steam client in Big Picture on your Adreno handheld, with Windows games through Valve's ARM64 Proton.
Requirements and install
Use Android 9 or newer on a supported Adreno device (730 or newer, or 8xx). Mali, Xclipse, PowerVR, and Adreno 710 are unsupported. No root is required. Allow about 3 GB for the runtime and 1.1 GB more for the desktop and emulators. Install the APK from Releases, install the Linux runtime, then press Play and sign in. Steam downloads on first launch. Install Desktop & apps to use the desktop and emulators. The Store installs Linux apps and games from Flathub (ARM64 builds) with Flatpak; see docs/development/flatpak.md.
On Android 12+, if Steam exits without a log, turn off Restrict child processes in Developer options.
Community
Join the DroidDeck Discord for help, nightly builds, and device reports. Bug reports go in its #bug-reports forum; attach the session folder from Download/DroidDeck/ so the logs come with it.
Build
Run tools/build_local.sh with Docker, Java 17, the Android SDK/NDK, and zstd installed. It builds the ARM64 audio sinks from PulseAudio 13.0 and packages them into the APK at app/build/outputs/apk/release/app-release.apk. Set DROIDDECK_PA13_SOURCE_DIR to an existing PulseAudio 13.0 source directory to skip downloading it. To install the APK on an attached device, run tools/deploy_local.sh.
Limits
Compatibility and performance vary by device; hardware validation is limited. Desktop compositing uses software rendering. Firefox sandboxing is reduced under proot. See the session logs in Download/DroidDeck/ when diagnosing problems.

LSFG frame generation is from the work of Camille LaVey and the Eden emulator project, following lsfg-vk, ported to WinNative and DroidDeck by @maxjivi05; it needs your own copy of Lossless Scaling and ships none of its shaders.
