How to fix the blurriness of DLSS Quality mode in Dune: Awakening?

I was so excited to see the real texture of the Dune world, but DLSS made distant dunes look like they had a soft-focus filter on them. I first tried switching DLSS from Quality to Balanced mode; FPS rose by 5, but the blurriness worsened, which was completely counterproductive. I used the GamePP DLSS/FSR Image Sampling Calibrator to raise sharpening intensity from 50 to 78 and locked resolution to 100%. RivaTuner showed a significant increase in effective pixels, GPU-Z reported VRAM at 6.2-7.1GB, and AIDA64 noted 58-64℃ to switch.
