LSFG Git is a tool for increasing frame rates in PC games by generating additional frames in real time, a process called frame generation. It builds on top of the Lossless Scaling application, which must be installed separately, and uses several LSFG algorithm versions (3.0, 3.1, and 4.0) to multiply the number of frames the game produces. The stated goal is to reach 2x, 3x, or 4x the original frame count, resulting in a smoother visual experience without requiring a more powerful graphics card. The project targets Windows 11 and Linux, including the Steam Deck handheld. On Steam Deck it operates through a plugin for a tool called Decky Loader. Alongside frame generation, the tool supports visual upscaling via AMD FSR and NVIDIA NIS, as well as integer scaling. A Vulkan integration layer called LSFG-VK is available for games that use the Vulkan graphics API. Installation is a download-and-run process: download a zip archive from the releases page, extract it, run the included installer as Administrator, then configure which frame generation mode to enable. The README includes a short troubleshooting table for common issues, covering problems like the app failing to start, visual artifacts, high input lag, and Steam Deck-specific setup steps. The README is brief. It notes that the project is for educational and personal use only, that the separate Lossless Scaling application is required, and that the authors disclaim responsibility for issues or license violations.
