Fixing PCIe Bandwidth Saturation
Driving through the neon lights of Night City, the frame rate would plummet from 70 to 35 in crowded areas, which felt lethal. I tried lowering texture quality in-game; while average FPS went up, the irregular stuttering remained per RTSS. I then used GamePP NVMe Queue Depth Config to set the depth to 2048 and updated the firmware. This dropped frame time volatility below 5% per GamePP Tool, with 4K reads reaching 72-80MB/s per CrystalDiskMark and temps at 48-55℃ per HWiNFO.
