Fix Noctua NH-D15S Driver Conflict in GTA V

Riding through Los Santos in GTA V, I noticed terrible texture popping and lag. RivaTuner revealed memory latency spiking to 92-105ns due to a lighting driver conflict. I tried disabling the device in Device Manager, which fixed the lag but killed the RGB effects entirely. That was a no-go. I used the GamePP Peripheral Driver Conflict Detection Tool to set the lighting service to Manual start and killed background syncs. RivaTuner showed frame intervals dropping from 14-42ms to a solid 8-11ms. MemTest86 confirmed zero errors, and the system ran stable without any visual artifacts.
