In that case it seems I might have some news for you guys, as here is the corsair.service.exe, even with this DLL blocked off and system monitoring shut down in iCue, delivering a pair of system-killing spikes in succession, not three hours into my tests.
the smaller ones are firefox and OBS and don't affect responsiveness. the two taller ones did kill the dpc, as process lasso's meter displayed. corsairservice can spike by 15 or 50% it doesn't matter, it has the same "my whole damn pc is buggered" effect.
this is completely unacceptable, on so many levels.
btw I've seen a pair of spikes like that, with pretty much the same spacing between them, several times now.
