GitHub hosts several free, open-source projects that offer similar spatial upscaling capabilities. Magpie is the most prominent alternative. It provides universal spatial upscaling (including FSR and Anime4K) for windowed games, though it lacks the proprietary frame generation capabilities of the paid Lossless Scaling app. 2.

Select Auto or Custom . If your hardware is weak, choose AMD FSR or LS1 (the proprietary spatial scaler) and set the scale factor to 1.5x or 2.0x. If you are struggling with low framerates or
However, version 3.2 narrowed the gap considerably. The improved X2 mode achieved image quality and latency comparable to DLSS 4, with artifacts being barely noticeable. In fact, LS 3.2 actually beat NVIDIA Smooth Motion in terms of image quality, especially when scaling moving objects. Magpie is the most prominent alternative

The official troubleshooting guide lists common issues: the tool may fail to detect the game (solution: use borderless windowed mode), visual artifacts (adjust settings or change mode), performance issues (lower multiplier), antivirus warnings (add the folder to exclusions), and black screens (run as Administrator and update GPU drivers).
