Lossless Scaling

I want to be clear up front: Lossless Scaling is not a game. It is a PC utility, and reviewing it like one is the only honest approach. What it does is intercept whatever is running in a windowed or borderless fullscreen mode and apply two distinct tricks: resolution upscaling using algorithms like LS1, FSR, or integer scaling, and frame generation via the LSFG model, a machine learning system built by solo developer THS specifically for this tool. The pitch is that you get smoother, higher-framerate gameplay in virtually any title without touching your hardware or waiting for a developer to patch in DLSS or FSR support. The upscaling side is the older half of the package and is straightforward. Run a game at a lower internal resolution, let Lossless Scaling push the output back up to your monitor's native resolution, and you claw back frame rate headroom. The LS1 model does a decent job keeping the image sharp, though it is not competing with a native DLSS implementation running inside the engine. Where things get genuinely interesting is the LSFG frame generation layer. Starting from LSFG 1.0 in early 2024, the tool added the ability to double, triple, or quadruple your rendered frame count on any GPU, including integrated graphics. By mid-2024 it had grown to support 3x and 4x multipliers, plus an adaptive mode that targets a framerate ceiling rather than a fixed multiple. For games locked at 60 fps by the developer, like Elden Ring or Tekken 8, being able to push the felt framerate to 120 fps without engine-level changes is the kind of thing that sounds like marketing until you actually try it. That said, the tool has genuine limits worth knowing before you hand over money. Frame generation works best when your GPU is already producing a solid, stable framerate before the multiplier kicks in. If you are starting from 40 or 50 native fps and asking LSFG to carry the load, added input latency becomes noticeable, especially in anything that demands precise controls or fast reactions. The tool also requires windowed or borderless fullscreen mode, which means exclusive fullscreen games need workarounds, and some configurations may conflict with overlays from Steam, Discord, or anti-cheat systems. Competitive online play is a grey area the developer acknowledges openly. On a VRR or G-Sync monitor, early versions of LSFG required users to disable variable refresh entirely to avoid frame pacing problems, though later iterations of LSFG addressed this meaningfully. Setup involves a real learning curve: capping framerates correctly, choosing between DXGI and WGC capture APIs, and dialling in GPU headroom are all things you will need to read about before the experience clicks. For the right player, though, none of that is a dealbreaker. If you run older titles that predate modern upscaling tech, play on a Windows handheld like the ROG Ally or Legion Go, use an emulator with a locked 30 fps output, or just want to uncap a console port that stubbornly refuses to go above 60, Lossless Scaling fills a gap that no first-party solution currently covers with the same hardware-agnostic flexibility. It earned a 93 percent positive rating across nearly 40,000 Steam reviews, which is unusual for a utility with this many configuration caveats. The community around it is active and well-documented, which helps considerably when something does not work on the first try.
