Solving memory bandwidth spikes on VastArmor RX 9070 XT?

Whenever I hit high-density areas like Pochinki, my FPS would plummet from 140 to 60 without warning, making gunfights an absolute nightmare. The VRAM bandwidth on the VastArmor RX 9070 XT Super Alloy was jumping between 450-520GB/s due to poor driver-level scheduling when loading heavy textures. I tried lowering the texture quality first, but the game looked like a blurred mess and the stutters remained—this whole troubleshooting process was a complete slog. I finally set my virtual memory to a fixed 32GB size and enabled VRAM compression optimization in the driver. In side-by-side tests, the frame time swings dropped from 15-40ms down to a manageable 12-18ms. I actually messed up and disabled SAM mode at one point, which cost me 15 FPS immediately, so I turned that back on to find the sweet spot. Core temps are now 65-72℃ and VRAM is hitting 88-92℃. The response time finally feels instinctive again.
