How to fix frame time spikes in DEAD OR ALIVE 6 Last Round on JGinyue X99M-PLUS D3?

Frame times jumped to 45ms during intense group battles. I tried disabling the camera, but it killed my stream. I used GamePP Peripheral Driver Conflict Detector to set Razer Synapse to Manual. RivaTuner showed frame intervals stabilizing from 8-45ms to 7-12ms. Task Manager reported CPU at 65-72%, and I verified the smooth performance.
