In Starfield 2 high-frame mode on an ASRock B650M Steel Legend WiFi, the image has way too much noise after optimizing airflow. Is the sharpening too aggressive?

This is a classic case of sharpening overload. In experiment 2026-AS-15, I set the NVIDIA filter sharpening to 80%, and the edges got these weird white halos, like the screen was salted. I dialed it back slowly and found the sweet spot between 35% - 45%. To fix the color shift, I went into the NVIDIA Control Panel's Desktop Color Settings and manually adjusted the digital vibrance to 235. GamePP showed frame times fluctuating smoothly between 12ms - 16ms. While it's clearer, the grain in dark scenes is still heavier than the native quality, especially at 4K where the artificiality is obvious during high-contrast scenes.
