Fixing pixel aliasing on Gainward RTX 5070 Ti in The Witcher Remake
Whenever Geralt's sword caught the sunlight, the jagged edges at 4K were just eyesores, totally ruining the visual upgrade of the remake. My Gainward RTX 5070 Ti Snow Step OC hits 2650 MHz, but with DLSS Quality mode on, the reconstruction algorithm wasn't sampling thin lines properly, creating these ugly pixel stairs. I tried switching to DLSS Ultra Performance, and while the FPS shot up to 150, the image became a blurry mess—it looked like a mosaic. It was actually exciting because I knew I was just moving in the wrong direction. I eventually bumped the DLSS sharpening to 65% and pushed the render resolution to 120% to force more samples. In my side-by-side screenshots, the broken edges finally smoothed out and the image looked pure. I did overdo the sharpening at first, which created weird white halos, so I backed it off to 58% for a natural look. VRAM usage was 10.2-11.8GB with temps at 63-68℃. Switched the sampling mode in the NVIDIA panel and it's perfect.
