Why does RX 7800 XT stutter during FF16 spells?
Whenever a full-screen spell goes off, my FPS crashes from 60 to 35—the optimization is honestly a joke. Even with 16GB of VRAM, the bandwidth utilization dipped by 15-22% during 4K sampling, choking the render pipeline. I tried Radeon Super Resolution (RSR), but it made the image look blurry and smudged, which just made me more frustrated. I eventually went into the advanced driver settings, set the shader cache mode to 'Override', and dropped Anisotropic Filtering from 16x to 8x. The frame time analyzer showed a drop from 20-45ms to a steady 14-18ms. I noticed some texture flickering on the ground after lowering the AF, but switching the AA mode to TAA fixed it. Temps are 68-75℃. I saved a system snapshot of the config, though the AMD software is still a bit clunky.
