Lossless Scaling:
Make your games
smoother

Lossless Scaling is a Windows utility that enhances games using AI frame generation and various scaling algorithms. It works with any game in windowed or borderless mode, even those without native support. The software uses proprietary LSFG (Lossless Scaling Frame Generation) technology to create additional frames, making games smoother without requiring new hardware.

Lossless Scaling requires windowed or borderless fullscreen mode to capture the game window. Exclusive fullscreen only works when outputting to a secondary display. Most modern games support borderless windowed mode, which provides the same visual experience as exclusive fullscreen while maintaining compatibility with Lossless Scaling.

The community has extensively tested Lossless Scaling with various online games and anti-cheat systems. It's widely reported as safe with most anti-cheat systems including EasyAntiCheat, BattlEye, and Vanguard. However, use at your own discretion as this cannot be guaranteed for all games. Check community forums for specific game compatibility.

Fixed mode multiplies your frame rate by a fixed amount (2x, 3x, or 4x). For example, 30 FPS becomes 60, 90, or 120 FPS. Adaptive mode lets you target any specific frame rate (like 75 FPS or 144 FPS) and handles variable FPS sources better. Adaptive mode is more flexible but may have slightly higher latency.

The LSFG (frame generation) feature is available on Linux through a community-driven port called lsfg-vk. This is a separate project that implements LSFG using Vulkan. Check the GitHub repository for lsfg-vk for installation instructions and compatibility information. The main Windows version requires Windows 10 or later.

For modern 3D games: Use LS1, FSR, or NIS. These maintain sharpness and detail. For pixel art games: Use Integer scaling for pixel-perfect upscaling, or XBR for slightly smoother edges. For anime-style games: Use Anime4K. For frame generation: Use LSFG Fixed for locked FPS games, or LSFG Adaptive for variable FPS. Experiment with different algorithms to find what works best for each specific game.

Dual GPU support allows you to offload frame generation or scaling processing to a secondary GPU. Your primary GPU runs the game at full performance, while the secondary GPU handles Lossless Scaling operations. This results in zero performance impact on the game and can even reduce input latency. Both GPUs must be from the same vendor (both NVIDIA or both AMD) for best compatibility.
