How to fix DLSS over-smoothing and flickering in Far Cry 6?

Sprinting through the rainforest, I noticed unsettling jagged flickering on the edges of the screen, which was incredibly distracting at 2K. I tried disabling V-Sync in the game settings; while latency dropped, the screen tearing actually worsened, leaving me feeling helpless. I used the GamePP DLSS/FSR Image Sampling Calibrator to raise sharpening to 68% and lock the sampling rate at 100%. RTSS contrast analysis showed edge noise dropped from 15-20% to 6-9%, with GPU temps stable at 65-71℃ per AIDA64 and a core clock of 1780MHz per GPU-Z.
