Why does Gray Zone Warfare have instant freezes when crossing forests with G.Skill Trident Z 3600 16GB?

The way this game munches through RAM is just ridiculous; 16GB feels like a joke here. When loading massive terrain assets, the Trident Z kit would hit 15.4GB instantly, putting the system into a severe I/O wait for 0.5-1.2 seconds, which just froze the screen. I tried closing every single background app, but other than making my chat apps useless, the stuttering barely changed—the optimization is just laughable. I went into advanced system settings, changed the processor scheduling to prioritize background services, and manually locked the page file write speed. In RivaTuner, the frame time spikes of 20-110ms finally settled into a more reasonable 15-28ms. I did run into some nasty audio tearing after the first tweak, which I only fixed by dropping the audio sample rate from 192kHz back to 48kHz. RAM temps stayed between 45-52℃. Used the internal profiler to export the logs, and the scheduling parameters are now solid.
