How to fix Kioxia Exceria Plus G4 SSD stuttering in Witcher?
Facing the massive open world of the Remake, I thought PCIe 5.0 speeds would mean instant loads, but entering Novigrad triggered a bizarre 200ms stutter that felt completely disconnected from the hardware specs. Checking the GamePP Hardware Sensor Page, I noticed the Kioxia Exceria Plus G4 was triggering constant CPU interrupts during high-concurrency reads, causing I/O wait times to skyrocket. I first tried updating the chipset drivers, but the stutters remained random, which was incredibly frustrating. I then dove into the GamePP NVMe Queue Depth Config, forcing the queue depth to 128 and enabling read-ahead cache optimization.
