Why does smoke cause frame drops in Star Wars on RX 9070 XT?

I panicked when frame intervals jumped from 8ms to 22ms during smoke scenes. I tried reducing particles, but the visual quality was a disaster. I used GamePP Resource Scheduler to set Real-time priority and optimize VRAM allocation. AIDA64 confirmed VRAM temp at 65-70℃ and utilization dropped from 95% to 85%. The frame time stabilized, and I saved the profile.
