Lossless Scaling is a professional Windows utility primarily distributed through the Lossless Scaling Steam Store page . It is not a fully open-source project, so the full "Lossless Scaling" executable is generally not hosted for direct download as a repository on GitHub.
The primary project for bringing LSFG to Linux. It implements a Vulkan layer to enable frame generation on Steam Deck and other Linux distributions.
Unlike NVIDIA's DLSS 3, which requires specific hardware (RTX 40-series cards) and game integration, Lossless Scaling’s Frame Generation works on almost any GPU (NVIDIA, AMD, Intel) and in almost any game. It works by interpolating frames between existing frames, effectively doubling or tripling the frame rate.
Offers various algorithms like LS1 (proprietary), AMD FSR, NVIDIA NIS, and Integer Scaling. These allow you to run a game at a lower resolution and scale it up to your monitor's native resolution with minimal blur. Compatibility:
