Why are textures blurry in Rainbow Six Extraction on MSI B450M?

While moving through the abandoned space station, DLSS Quality mode made character facial textures look blurry and unclear, which was really annoying. I initially tried switching DLSS from Quality to Balanced mode, but the blurriness actually worsened, making the scene look even more washed out. I decided to use the GamePP DLSS/FSR Image Sampling Calibrator to increase the DLSS sharpening intensity from the default 50 to 75. The GPU temperature remained stable at 56-62℃ per HWiNFO, and fan speed held at 1500-1700 RPM via GamePP.
