Why does Marvel Puzzle Quest stutter during streaming on the Intel 660P 1TB drive?

Frame time jumped from 8ms to 45ms during battles. It was a fatal fluctuation. I tried disabling the camera in Device Manager, but that killed my stream. I used the GamePP Peripheral Driver Conflict Detector to set Razer Synapse to Manual sync and enabled Hardware Encoding Priority in OBS. RivaTuner confirmed the interval stabilized at 7-12ms. Task Manager showed CPU usage dropping to 65-72%. It’s a vital verify step for streamers.
