How do I fix blurry wall textures in House Flipper Remastered with DLSS?

I was frustrated by the blurry walls in House Flipper Remastered while using DLSS Quality mode. It looked like a low-res mod. I tried switching to Balanced mode, but it was even worse and lost all detail. I used GamePP DLSS/FSR Image Sampling Calibrator to increase sharpening intensity from 50 to 75. Now, GPU temp is stable at 56-62℃ per RivaTuner, and fan speed is 1500-1700 RPM. The textures are crisp again, and my Kioxia EXCERIA PLUS G3 2TB SSD handles the asset loading smoothly.
