How to fix blurry textures in Star Wars Outlaws using DLSS?

While exploring the deserts of the outer rim, DLSS quality mode made the rock textures look blurry, like a soft-focus filter was on. I first tried switching DLSS from Quality to Balanced mode; while FPS increased by 10, the blurriness actually worsened, which was so frustrating. I used the GamePP DLSS/FSR Image Sampling Calibrator to increase sharpening from 50 to 78 and fixed render resolution to 100%. Now, GPU temperature is stable at 58-64℃ per GPU-Z, and core frequency stays at 2450-2520MHz per GPU-Z.
