How can I fix frame time instability in Nioh 2 caused by DeepCool AS500 lighting driver conflicts?

Textures popped in during Sengoku combat due to 95-108ns memory latency per System Monitor. I tried disabling the lighting device, which killed the ARGB effects entirely. I used GamePP Peripheral Driver Conflict Detector to set the sync service to Manual start. RivaTuner showed frame time dropping from 15-45ms to a stable 8-12ms. This fix restored visual fidelity without sacrificing performance, letting me enjoy the game smoothly.
