• NVIDIA DLSS Implementation (For RTX cards): Although Nioh is older, this update back-ported better rendering logic for higher resolutions, allowing 4K gameplay without sacrificing the 60 FPS target.
• Bug Fixes: Removed the infinite “Toad” item glitch and fixed a progression blocker in the "Spirit Stone Huntress" mission.
