[QUOTE="Owlsroost, post: 607991, member: 83973"] I've only seen it get it wrong once, immediately after an auto refresh rate change, but I've seen the windows reported refresh rate incorrect much more often (after refresh rate changes). Also the windows reported rate(on Vista at least) is only an integer value, e.g it reports '59' for nVidia actual 59.94Hz refresh rate, so it's inaccurate anyway. It does a tight (currently within 2%) comparison of video-to-display rates to decide if vsync correction is possible, so if it gets the rate measurement wrong it just means the vsync correction is disabled. I'd like to measure the display refresh rate continuously (with minimal overhead), but I haven't come up with a good method so far..... Tony [/QUOTE]
