Set your game to Windowed or Borderless Windowed mode. The app scales the game's window rather than taking over exclusive fullscreen.

For a long time, frame generation technology was locked behind specific hardware walls. If you didn't have an RTX 40-series card, you were out of luck. Lossless Scaling (LS) broke that wall, but earlier versions were sometimes clunky, prone to artifacting, or introduced frustrating input latency. With version 3.1.0.0, the tool has matured from a "cool tech demo" into a legitimate, stable performance layer that rivals native driver-level solutions.

Lower the game's internal resolution below your monitor's native resolution (e.g., if you have a 1440p monitor, set the game to 1080p).

Despite improvements, users may still encounter artifacts at high scaling factors and increased input latency compared to native solutions. Getting Started with v3.1.0 To get the best results, it is recommended to: Cap your base FPS at a stable number (minimum 30 FPS). Set the game to Borderless Fullscreen Lossless Scaling Steam Page

The hallmark of the 3.1.0.0 update is the refinement of the . Unlike previous iterations, this version offers vastly improved stability and reduced artifacting, particularly in fast-motion scenes. By decoupling frame generation from specific GPU architectures, it allows users with older hardware—or even handhelds like the Steam Deck and ROG Ally—to experience "fake" frames that feel remarkably close to native fluid motion. Key technical improvements in this version include:

: Games that were never designed to run at high refresh rates or widescreen resolutions.

A highly optimized, custom upscaler created by the developers. It is excellent for modern, 3D games and works better than traditional Bilinear filtering for non-native resolutions.
