How to fix FSR jagged edges on Vastarmor Radeon RX 9070 XT?
When the monsters charge, the edges of the screen get these ugly stair-step jaggies that are impossible to ignore. While the compute units on this Vastarmor card are beasts, FSR was over-smoothing the edges, leading to a massive loss in sharpness at 4K. I tried turning FSR off to run native, but my FPS tanked from 85 down to 42, which was a total letdown. I eventually dove into the AMD Adrenalin panel, cranked the RSR sharpening to 70%, and manually locked the in-game render scale to 105%. Monitoring via RivaTuner, I could see the effective pixel count increase, and the monster scales finally looked detailed again. I actually pushed sharpening to 100% at first, but it created these weird white halos around objects, so I backed it off to 68% for the sweet spot. Core temps are 61-67℃, fans at 1700-1900 RPM, and frame times are now a stable 5.1-6.4ms.
