Trying it out in Shadows of Doubt right now, took performance from an unstable 25-31 fps to 61-71 fps with I set on performance mode and x2 fps. Don't really notice input lag.

It's not on the decky store yet, so you have to download the extension zip manually.

Here's the extension github with full instructions and details.

Basically you'll:

Install the plugin. Once it's on the decky store you can install it from there, but in the meantime do this:
- Download the .zip from the release page
- In Game Mode, go to the settings cog in the top right of the Decky Loader tab
- Enable Developer Options
- In the new Developer tab, select "Install from zip".
- Choose the "Lossless Scaling.zip" file you downloaded (likely in the Downloads folder)
- If it does not show up, you may need to restart your device
Purchase and install Lossless Scaling from Steam
Open the plugin from the Decky menu
Click "Install lsfg-vk" to automatically set up the compatibility layer
Configure settings using the plugin's UI controls:
- Enable/disable LSFG
- Set FPS multiplier (2-4) Note: The higher the multiplier, the greater the input lag
- Enable performance mode - Reduces gpu load, which can sometimes majorly increase FPS gains
- Adjust flow scale (0.25-1.0)
- Toggle HDR mode
- Toggle immediate mode (disable vsync)
Apply launch commands to the game you want to use frame generation with:
- Option 1 (Recommended): ~/lsfg %COMMAND% - Uses your plugin configuration
- Option 2: Manual environment variables like ENABLE_LSFG=1 LSFG_MULTIPLIER=2 %COMMAND%

Since it didn't crash you, but didn't seem to kick in, check and make sure that you're not full screen on your in-game settings. Go windowed or bordered instead.

I have used it a handful of times on Windows and that was always a prereq to get it to do anything.
