SSIM/PSNR metrics indicate v2.1.1 delivers superior detail retention compared to earlier versions and competitors.

There is a quiet revolution happening in the PC gaming space, and it isn’t coming from NVIDIA’s DLSS 3 or AMD’s FSR 3. It’s coming from a tiny utility on Steam called . Lossless Scaling v2.1.1

The (part of the broader 2.x and subsequent 3.x development branch) solidified the app’s reputation as an indispensable tool for gamers looking to boost performance on laptops, handhelds like the Steam Deck, and older desktops. What is Lossless Scaling? SSIM/PSNR metrics indicate v2

: To balance the increased GPU load of newer algorithms (which can be 1.5x–2x higher than older versions), a "Performance" mode was added to maintain the speed of earlier versions while keeping the quality benefits of the new architecture. The (part of the broader 2

The LS1 Performance (P) model is a game-changer for those who prioritize frame rates. By offering up to 40% faster performance, it allows users with weaker GPUs to access high-quality upscaling without a prohibitive performance hit .
