How to stop I/O blocking on Samsung 9100 PRO in AC Shadows?
It's honestly a joke that a top-tier PCIe 5.0 drive can still cause frame drops. While sprinting through Kyoto, my FPS would tank from 140 down to 80. The GamePP sensor page showed the SSD hitting 78°C, triggering a slight thermal throttle. I tried switching the power management to 'Maximum Performance' in the driver, but other than making my fans scream, the drops stayed exactly where they were—a completely pointless exercise. I eventually used the GamePP NVMe Queue Depth Config to optimize the depth to 256 and tweaked the motherboard's PCIe link state. In benchmarks, random read performance climbed by 8%, and the drops became rare.
