I did that and there really is no mentioning in the report of any process requesting a certain timer resolution (I started Crysis 3 without starting Origin first via some way). So it must indeed be Windows (or the video driver?) itself that sets it. Though the report is not correct regarding what allegedly is the timer resolution in use after running the command, or it measures it only once before Crysis 3 gets started. It reports 15.6ms, which contradicts other tools and the actual performance.
