Fix SLC Cache Overflow Stutter
I was mid-jump in Midgar when the Samsung 990 PRO 4TB hit SLC cache limits, dropping read speed to 900MB/s. I tried tweaking virtual memory, but it made the stutter worse. I used GamePP NVMe Queue Depth Config to raise the queue depth from 1024 to 2048 and forced write cache flush. CrystalDiskMark showed 4K random read jumped from 50-55MB/s to 70-78MB/s. Loading dropped from 12s to 5s. This stable performance is the key to save your session.
