For gamers and developers, choosing preset L can yield noticeably better visual fidelity and fewer distracting artifacts in many titles without performance trade-offs, simplifying configuration decisions for higher-quality upscaling. That matters for user experience and for how developers recommend default settings to players.
Nvidia’s DLSS 4.5 introduces two models—preset M (performance-oriented) and preset L (ultra-performance-focused)—and real-world testing shows preset L often delivers the best overall image quality across regular modes. Preset L tones down the oversharp, crunchy look of preset M while keeping comparable clarity and motion stability, and notably improves grass/foliage rendering and some particle/background pixelation. Both L and M share occasional pattern artifacts and similar fine-detail reconstruction limits, but both reduce ghosting versus the older DLSS 4 preset K. Overall, preset L is the preferred choice for a more natural, less grainy upscale without sacrificing the motion clarity gains of DLSS 4.5.
