My WD SN850 lags out and crashes the game whenever I save a large file in Horizon Forbidden West, do I need to fix virtual memory?

Every time I save, the game freezes for about 3 seconds and then just crashes to desktop without any error code, which is incredibly frustrating. Once the SLC dynamic cache on the WD SN850 fills up, write speeds plummet from 6500MB/s to under 800MB/s, causing a total I/O bottleneck. I tried setting my page file to half of my remaining disk space, but in a massive open world, that just made the stuttering worse. I eventually went into Device Manager, bumped the NVMe controller queue depth from 1024 to 2048, and enabled 'Force Write Cache Flushing' in Windows performance options. CrystalDiskMark showed 4K random writes climbing from 40-50MB/s to 62-70MB/s, and the save-game freezes are gone. I noticed some weird wake-up lag in idle after the change, but switching to the High Performance power plan killed it. Temps are now 42-55℃ with response times at 28-35ms. Everything feels snappy now.
