Why does frame time jump to 45ms in Star Wars Outlaws on Onda H610M?

Combat frame times jumped from 8ms to 45ms. I tried disabling the camera, but it killed my stream. I used GamePP Peripheral Driver Conflict Detector to set Synapse service to Manual. I enabled hardware encoding in OBS. RivaTuner showed intervals converging to 7-12ms. CPU usage stayed at 65-72%. Fan speed was stable at 2200-2500 RPM. The stream is now smooth.
