Fixing PCIe Low-Power State
While traversing nightmare scenes, sharp details appeared smeared, which was extremely distracting at 4K. I first tried lowering texture quality in-game, but the visuals became crude and loading delays remained, leaving me anxious. I used the GamePP Power Plan Switcher to lock High Performance mode and set storage I/O priority to maximum via Resource Scheduler. Sequential reads stabilized at 3200-3400MB/s per CrystalDiskMark, read latency hit 15-30ms via AIDA64, and temps were 42-50°C per HWMonitor.
