Lossless Scaling is a premium, highly-rated utility for Windows PC that allows gamers to scale up windowed video games using advanced spatial and frame-generation algorithms. Developed by THS, it is primarily designed to improve gaming performance on lower-end hardware, handheld consoles (like the Steam Deck or ASUS ROG Ally), and to smooth out older games that lack modern scaling features.

Core Technologies & Features

LSFG (Lossless Scaling Frame Generation): Adds artificially generated frames between existing frames using specialized machine learning models, allowing users to effectively double or triple their visual frame rate (e.g., boosting a native 30 FPS target to 60 FPS, or 60 FPS to 120 FPS or 180 FPS).

LS1 (Spatial Scaling): A proprietary, state-of-the-art scaling algorithm optimized for modern games that delivers crisp visuals with minimal performance overhead.

Universal Game Compatibility: Works with virtually any game or application because it runs directly on the Windows desktop environment rather than integrating via the game engine.

Legacy Up-scalers: Includes built-in support for open-source algorithms like AMD FidelityFX Super Resolution (FSR), Nvidia Image Scaling (NIS), Integer Scaling, and Anime4K.

Requirements & Best Practices

Operating System: Exclusively supports Windows 10 (64-bit) or Windows 11.

Display Mode: Games must be configured to run in Windowed or Borderless Windowed mode for the utility to hook into the visual feed.

Baseline Frame Rate: Requires a stable, locked base frame rate (usually a minimum of 30 or 40 FPS) to prevent noticeable visual artifacts and input lag during frame generation.
