Description

  • Update LSFG Vulkan layer to v1.3.3, improve layer stability and prevent freezes in external mode
  • Move LSFG layer .so file from assets to jniLibs, treating it as a native library.
  • Prevent post-install cloud save synchronization and container creation for the Lossless Scaling utility app (App ID 993090) as it does not manage game saves.
  • Optimize Lossless.dll discovery by directly searching Steam install paths, bypassing container creation for the utility app, also check and delete existing created container to save storage space

Summary by cubic

Updates the Lossless Scaling Frame Generation integration to v1.3.3, bundles the Vulkan layer as a native library, and stops creating/syncing a Steam container for app 993090 to improve stability and avoid external‑mode freezes. Previously we copied the layer from assets and created a container with post‑install cloud save sync; now we load from jniLibs, read Lossless.dll directly from Steam paths, skip container/sync, and remove any existing container.

  • Moves liblsfg-vk-layer.so to jniLibs/arm64-v8a; LsfgVkManager copies from applicationInfo.nativeLibraryDir, while keeping the manifest in assets with a patched library_path.
  • Skips post‑install cloud save sync and container creation for Lossless Scaling (App ID 993090) in SteamService; emits PostInstallSyncStatusChanged(false) and fixes the container ID format to STEAM_993090.
  • Discovers Lossless.dll by scanning SteamService.allInstallPaths using the app’s installDir, with a fallback directory search; deletes any existing STEAM_993090 container to save space.
