How to fix FSR blur on Sapphire RX 7800 XT 16G?
The excitement of exploring this ancient world was completely killed by the smearing effect of FSR. While the Sapphire RX 7800 XT has great core clocks, FSR over-smoothed the high-frequency details during frame reconstruction, making roof tiles and fabric look like an oil painting. I first tried switching from FSR Quality to native resolution, but my FPS tanked from 82 down to 40—a performance hit that felt devastating. I then dove into the AMD Software and manually cranked Radeon Image Sharpening from 15% up to 65%, while locking the in-game render scale to 108%. In side-by-side screenshots, the blurry edges snapped back into focus, and distant mountain silhouettes finally looked sharp. I did try pushing the sharpening to 90%, but that created ugly white halo artifacts around edges, so 65% became the sweet spot. GPU temps hovered between 62-68°C and VRAM usage stayed at 10.5-12.8GB. Image calibration tools confirmed a massive jump in clarity, and the GPU core stayed stable at 62-68°C.
