I'm getting huge stutters during large battles in Expeditions Rome on my Sapphire RX 7800 XT Polar Edition. Should I rollback drivers?

Seeing thousands of Roman soldiers clash is an epic sight, but it was ruined by these random, jarring freezes. The Sapphire RX 7800 XT Polar Edition was struggling with Vulkan API calls, causing the frame time to jump from 12ms to a hideous 85ms. I tried the latest Beta drivers first, but that was a mistake—it just led to constant driver timeouts, which was incredibly frustrating. I used DDU to wipe everything clean, rolled back to the previous stable version, and manually purged 4.2GB of shader cache. RTSS showed the frame times settling back to 13-16ms, and the stuttering vanished. The game took an extra 20 seconds to launch after the rollback, but that went away once the shaders recompiled. GPU temp is steady at 61-67℃ with VRAM usage between 10.5-12.1GB. The render interface is finally switched and stable at 10.5-12.1GB.
