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:

  1. 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

  2. Purchase and install Lossless Scaling from Steam

  3. Open the plugin from the Decky menu

  4. Click “Install lsfg-vk” to automatically set up the compatibility layer

  5. 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)

  6. 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%

      I don’t know about anyone else, but the reason I say stuff like “fake frames, real flames” about nvidia, is that they include framegen in their performance stats.

      As if it’s a tech that boosts actual performance. They use it to lie.

      When they say “this card is twice as powerful as last gen” what they really mean is, it is exactly the same, but we turned on 2x framegen. Nevermind that there’s no reason you couldn’t do the same on the last gen card.
