Why is my Kioxia EXCERIA PLUS G4 2TB hitching in Ghost of Yotei?
While traversing the open snowfields, I hit these annoying micro-stutters that synced perfectly with storage read spikes. Once the Kioxia EXCERIA PLUS G4's dynamic SLC cache filled up, write speeds plummeted from 10,000MB/s to under 1,200MB/s, pushing read latency into the 35-55ms range. I first tried bumping up the Windows page file size, but that was a total nightmare—it actually worsened the I/O conflicts in the open world and increased the frequency of frame drops. I was honestly baffled. Then I dove into the GamePP NVMe Queue Depth Config and pushed the controller queue depth from 1024 to 2048, while forcing the write cache flush policy at the system level.
