In Expeditions: Rome, my FPS tanks from 110 to 40 during legion charges on a Manli RTX 5080. Should I mess with page files?

When the screen fills up with soldiers, the game turns into a slideshow, making tactical commands a complete joke. The GPU is pinned at 94-98%, but the CPU scheduler is hitting a wall with 15-20ms wait locks. I tried lowering the global illumination, but it only gained me 12 FPS and made the lighting look flat—not a trade-off I was willing to make. Instead, I used DDU to wipe everything and installed the latest Studio drivers, then nuked three redundant background monitoring services. Checking via RTSS, the 1% lows jumped from 38 to 55 FPS, and frame times tightened from a wild 18-45ms range down to a steady 12-17ms. I actually broke the game launch after disabling services initially, but a DirectX runtime reinstall fixed it. Core temps are 68-74℃, VRAM is 82-88℃. The stuttering is mostly gone, though some micro-stutters remain in extreme chaos.
