Why is MGSV lagging on my Kioxia EXCERIA PRO 1TB?
While sneaking through the open fields of Afghanistan, I noticed micro-stutters every time I whipped the camera around; the vegetation just wouldn't load in time, making my high-end gear feel like a potato. I checked the logs and the Kioxia EXCERIA PRO 1TB's random reads were swinging wildly between 45-52MB/s, causing the game engine to hang for 120-150ms. I wasted time trying to reformat and repartition the drive, which actually made load times 2 seconds slower—a total nightmare. I eventually dove into Device Manager, disabled the 'Write Cache Buffer Flushing' policy, and ran an NVMe-specific optimization. In CrystalDiskMark, my 4K reads jumped from 42MB/s to a steady 58-64MB/s, and the jarring hitches basically vanished. I did have a scare where I lost some file indices after a sudden power cut right after disabling the cache, but setting up a small fixed-size page file fixed the stability. Temps stayed chill at 42-48℃. With the IO queue depth finally sorted, my frame times are rock steady at 5.1-6.4ms.
