GoKawiilNvidia details DLSS 4.5 preset options for different GPU tiers
Nvidia's DLSS 4.5 introduces several model presets—K, M, and L—accessible through the app under Graphics > Global Settings > DLSS Override. Preset K targets high-end GPUs for maximum image quality, preset M suits mid-range cards like the RTX 4070 by upscaling from 1080p, and preset L is aimed at older RTX 20 and 30 Series cards, upscaling from 720p for better performance at some cost to image stability.
