Figures from each repo's GitHub metadata at analysis time.
Requires purchasing the separate paid Lossless Scaling app on Steam, Linux setup needs the lsfg-vk Vulkan layer configured.
LSFG GitHub is a repository that distributes files related to Lossless Scaling Frame Generation, a technology that multiplies the frame rate of games in real time. Frame generation means the software creates additional frames between the ones your GPU actually renders, making games appear to run at two, three, or four times their native frame rate. The repository offers versions using the LSFG 3.0, 3.1, and 4.0 algorithms. The README says it supports several upscaling and display technologies: AMD FSR (FidelityFX Super Resolution), NVIDIA NIS (Image Scaling), and Integer Scaling, which are different approaches to making lower-resolution images look sharper on higher-resolution screens. There is also support for a component called lsfg-vk, which is a Vulkan layer that brings the same frame generation capability to Linux and the Steam Deck handheld gaming device through a plugin for the Deck's Decky Loader system. The repository provides a download link for a zip file named LosslessScaling.zip and a short installation guide: extract the archive, run the installer as Administrator, set up the Vulkan layer if on Linux, configure the frame generation version in settings, and launch a game. The troubleshooting section covers common issues like antivirus interference, high input lag, visual artifacts, and driver compatibility with AMD and NVIDIA cards. The README includes a disclaimer that the project is for educational and personal use only, that the authors are not responsible for issues or license violations, and that it requires the Lossless Scaling application. The Lossless Scaling application is a separate paid product sold on Steam. The README does not include source code or documentation for how the frame generation algorithms themselves are implemented.
This repo distributes files for Lossless Scaling Frame Generation, which multiplies a game's frame rate by generating extra frames in real time, plus Linux/Steam Deck support via a Vulkan layer.
Mainly C#. The stack also includes C#, Vulkan.
Distributed for educational and personal use only, the underlying Lossless Scaling app is a separate paid Steam product, and the authors disclaim responsibility for license violations.
Setup difficulty is rated moderate, with roughly 30min to a first successful run.
Mainly general.
