I'm seeing huge FPS drops in high-detail scenes on my 9060 XT, is this a bandwidth issue?

Looking at the insane skin textures in this game, my FPS would just dive from 60 to 35. The optimization is honestly a joke. Even with 16GB of VRAM, the Vastarmor RX 9060 XT was seeing bandwidth utilization drop by 15-22% in specific 4K scenes, clogging the whole render pipeline. I tried Radeon Super Resolution (RSR), but the image got this weird blur that made me want to pull my hair out. I eventually went into the advanced driver settings, set the shader cache to 'Override', and dropped Anisotropic Filtering from 16x to 8x. My frame time analyzer showed a drop from 20-45ms to a smooth 14-18ms. I did notice some flickering on the ground textures at first, but switching the anti-aliasing to TAA fixed it. The card is running at 68-75℃. I saved the config as a snapshot because I'm not going through that headache again.
