I'm getting massive frame drops while galloping in Ghost of Tsushima with 8GB RAM, why is this happening?

Whenever I'm speeding across the open fields in Tsushima, my Kingbank Yin Jue 8GB DDR4 3600 hits a wall at 7.6-7.9GB. This memory starvation triggers aggressive page swapping, causing frame times to swing wildly between 12ms and 45ms—it's basically a slideshow. I tried dropping textures to Low, which saved about 0.5GB, but the game looked like a blurry mess, which was just frustrating. I eventually dove into System Advanced Properties and locked the virtual memory to a fixed 16GB on my fastest NVMe partition. Checking Resource Monitor, the hard page faults plummeted from 150/sec to around 20-35/sec, and my FPS finally settled into a stable 55-62 range. Weirdly, my boot times slowed down right after the tweak until I disabled Fast Startup. Temps stayed chill at 42-48℃ with disk latency around 0.8-1.2ms. It's a bit of a band-aid for low RAM, but it works.
