How to fix the blurry AI upscaling in Horizon Forbidden West?

This is a classic struggle between over-sharpening and blur. At first, I cranked the GPU filter sharpening to the max, but the image got these hideous white edges—it looked like a cheap oil painting. In environment 2026-06-E, I gradually bumped the sharpening from 0% and finally locked it between 35% - 42%, with detail enhancement at 20%. GamePP showed the GPU core clock staying steady at 2580MHz - 2610MHz, with frame times between 12ms - 15ms. It looks way cleaner now, though I noticed some slight ghosting during fast turns, likely due to the post-processing overhead. Still, it's a tiny price to pay to get rid of that original smudge.
