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%

    Make sure games are windowed or borderless and that you don’t have an external frame cap like steam overlay.

      It’s funny because after rebooting, the performance in Tamcoma was halved for no reason. Then I disabled fullscreen and the performance got better indeed. The funny part? The performance with Lossless Scaling on and fullscreen off is the same as the performance with lossless scaling off. Touching the other options in the plugin don’t change anything.

        Some games don’t get any performance increase, so you’ll have to try it game by game. So far most games I’ve tried have worked, but maybe I’ve just been lucky.

          I tried The Invincible too, it gave me a black screen with it activated. Success after success! I’ll keep trying more games in the following days, some have to work sooner or later.
