How to fix FSR blurring in Way of the Hunter with RX 9070 XT?

While tracking prey in the jungle, distant leaf textures were too smooth, which seriously hindered my observation. I tried cranking up the global graphics settings, but frames dropped from 120 to 85 while the blur remained—an unacceptable compromise. I used the GamePP DLSS/FSR Image Sampling Calibrator to raise FSR sharpening to 72 and adjust the sampling offset. Now, GPU temperature stays at 64-67℃ per AIDA64 and sampling rates are 70-85% per GPU-Z. The detail is back.
