what is lsfg-desktop fr?

This project is a Windows download labelled Lossless Scaling. The README presents it as a small desktop application that sits on top of games and other programs and tries to make them look sharper and run at a higher frame rate, without the user having to change settings inside each game. The README mentions two main techniques. The first is upscaling, where the image is rendered at a lower resolution and then enlarged to fit the screen using algorithms such as lossless integer scaling. The second is frame generation under a brand name the project calls LSFG, which creates extra in-between frames so the game appears smoother than the underlying engine is actually drawing. The README claims this gives sharper visuals and significantly higher FPS, the term gamers use for frames per second. The author notes that the build is optimized for Windows 10 and Windows 11. A short note in the README says the tool is intended for personal use with games and applications the user legally owns. Installation, as described, takes a few steps. Download the zip from the releases page, extract it, run LosslessScaling.exe as Administrator, set the target game to Borderless Windowed mode, then turn on the desired scaling mode and LSFG inside the app. The README closes with a troubleshooting table. If the tool does not detect a game, switch the game to Borderless Windowed mode. If you see visual artefacts, adjust the Flow Scale slider or pick the Performance mode. If performance feels low, lower the multiplier or turn off heavy sharpening. If an antivirus tool flags the folder, add it to the exclusions list. If the screen goes black or the app crashes, run as Administrator and update the graphics card drivers.
