What is lossless-scaling?

This repository describes a Windows tool called Lossless Scaling that claims to improve game visuals and increase frame rates. According to the README, it works by upscaling games using integer scaling algorithms and generating additional frames using a technology the project calls LSFG. You set the game to borderless windowed mode, then enable a scaling mode and frame generation from the tool, and the claim is that you get a sharper image and higher displayed frame rate. The README is very sparse. It does not explain what the software actually contains, how the upscaling or frame generation works technically, or what hardware it requires beyond Windows 10 or 11 and Python 3.8 or later. The primary installation method described is a single Windows command that runs msiexec to silently download and install a package from a third-party website not associated with this repository. The manual installation path clones the repository and runs a Python script. No external Python dependencies are listed. The README uses placeholder text in its links, referring to "YOUR_USERNAME" rather than the actual repository path. The README does not describe the project's history, who made it, or what the Python code in the repository actually does.
