I went in and put low latency · low latency set to "on" in nvidia driver (ie 1 maximum prerendered frame) mouse feels a lot more responsive than off/3 max prerendered frames, its very noticeable just by turning mouse around fast, mouse feels much "lighter" compared to off/3 MPRF, picture/motion is perhaps very slightly less smooth but there is no framedrops and a much better option for input delay compared to off/06/17 · NVCP VSYNC oninput lag is more lower then off right ?
