How do I fix the over-smoothed facial textures in Assassin's Creed Valhalla with DLSS Quality?

Playing Assassin's Creed Valhalla in 4K was frustrating because every close-up looked like a painting. The DLSS Quality mode was over-smoothing the textures, making faces look blurry and flat. I tried switching to Balanced mode to get more FPS, but it only made the blurriness worse. I needed a calibration fix. I used the GamePP DLSS/FSR Image Sampling Calibrator to increase the sharpening intensity from 50 to 72 and set the render resolution to 100%. MSI Afterburner confirmed my GPU temperatures stayed stable at 56-62°C.
