 A Decky plugin that streamlines the installation of **lsfg-vk** ([Lossless Scaling Frame Generation Vulkan layer](https://github.com/PancakeTAS/lsfg-vk)) on Steam Deck, allowing you to use the Lossless Scaling frame generation features on Linux with a controller friendly UI in SteamOS, Bazzite, or any other Linux platform compatible with Decky Loader.

 The plugin provides several configuration options to optimize frame generation for your games:
 
 ### Core Settings
-- **FPS Multiplier**: Choose between 2x, 3x, or 4x frame generation
+- **FPS Multiplier**: Choose between 1x, 2x, 3x, or 4x frame generation
 - **Flow Scale**: Adjust motion estimation quality (lower = better performance, higher = better quality)
 - **Performance Mode**: Uses a lighter processing model
 - **Allow FP16**: Enable half-precision acceleration; disable it for older NVIDIA GPUs
 - **Active In**: Optionally match a profile to executable names, Wine executables, or process names
 - **Automatic Profile Matching**: Explicitly let lsfg-vk choose an `Active In` profile; otherwise the Decky-selected profile is always forced
 - **GPU**: Optionally select the GPU by name, vendor/device ID, or PCI bus ID
-- **Disable Frame Generation**: Disable the layer for the next launch without creating an invalid 1x profile

+- Downloads checksum-pinned statically linked x86_64 or Armada/aarch64 lsfg-vk v2 layers to `~/.local/lib/`
 - Bundles checksum-pinned lsfg-vk v2 Flatpak extensions for runtimes 23.08, 24.08, and 25.08, and installs the selected local bundle
 - Updates already-installed user Flatpak runtimes and migrates the plugin's legacy app overrides when the native layer is updated
 - Records existing Flatpak runtime commits and rolls back already-updated runtimes when a multi-runtime migration fails, when Flatpak permits it

 - Migrates the existing `~/.config/lsfg-vk/conf.toml` from v1 to v2 automatically on layer update, retaining a one-time `.v1.bak` backup
