Why are wall textures blurry in DLSS Quality mode during interior renovation in House Flipper Remastered?

While renovating interiors, DLSS Quality mode made wall textures blurry, losing high-frequency details. I tried switching to Balanced mode, but blurriness worsened. I then used the GamePP DLSS/FSR Image Sampling Calibrator to increase sharpening intensity from 50 to 75 on the Kioxia EXCERIA PLUS G3 2TB NVMe system. GPU temperature remained stable at 56-62℃ and fan speed at 1500-1700 RPM, confirmed by RivaTuner. The textures are now sharp, restoring visual fidelity.
