Overview

Lossless Scaling is a powerful Windows-based tool (available on Steam) that uses AI-based frame generation and integer scaling to improve performance and visual quality in retro and modern games. Currently, it must be manually launched and configured, often through macros or startup profiles, which breaks the seamless “one-click launch” experience that LaunchBox is known for.

This request is to integrate Lossless Scaling directly into LaunchBox, enabling users to launch games with predefined scaling profiles automatically—no manual launching or switching apps required.

Proposed Features

1️⃣ Automatic Launching with ROMs

• When launching a game from LaunchBox or Big Box, allow LaunchBox to automatically launch Lossless Scaling in the background (if it’s not already running).

• Once the game window is detected, LaunchBox could trigger the scaling macro or point Lossless Scaling to the right preset.

2️⃣ Game-by-Game Configuration

• In each game’s metadata or edit menu, add an option to:

• Enable/disable Lossless Scaling

• Select a profile or scaling mode (e.g., Integer Scaling, LSFG for frame generation, etc.)

• Optionally specify custom commands or flags if advanced users want full control.

3️⃣ Profile Recognition & Management

• LaunchBox could look for existing Lossless Scaling profiles stored on disk and allow users to associate them with games manually.

• Bonus: Provide a way to import/export profiles within LaunchBox for easy sharing or backup.

4️⃣ Optional Steam Integration

• If Lossless Scaling must be launched via Steam, LaunchBox could optionally use a custom Steam URI handler (e.g., steam://rungameid/...) to open it quietly in the background.

Use Cases

🎮 Retro titles with low native resolutions where integer scaling improves clarity

🎮 Low-framerate games where frame generation helps smooth gameplay

🎮 Portable setups (e.g., Steam Deck, mini PCs) where performance and visual quality need balance

🎮 Users aiming for seamless, polished launching workflows without needing to open extra tools
