How to fix memory overflow in Civ 7 with Corsair LPX DDR4?

Once the game hits the late stage, switching turns became a grueling wait. With only 16GB, the memory usage was pinned at 98-100%, triggering constant hard page faults and spiking response latency from 10ms to a miserable 120ms. I tried lowering environment effects, which gave me a pathetic 5 FPS boost but did nothing for the turn-based freezing. I realized the page file was the bottleneck. I went into Advanced System Settings and manually locked the virtual memory initial and maximum size between 16384-20480MB. Checking Resource Monitor, hard page faults dropped from 30/sec to about 2-5/sec. I initially tried 12GB, but still felt some hitching on massive maps, so 20GB was the sweet spot. Temps stayed around 42-48℃. Verified the snapshot and the overflow is gone.
