I translate portuguese to english: "much thanks! but the change of the steps (forceware to driver - english): right click botton “icone nvidia” in the bar Start - > click “nvidia display” - > refresh rate overrides - > chooses 50 Hz of any resolution - > I get to work in any fullscreen gaming! 50 Hz + 50 frames per second = without frame-to-frame (up to infinity fps real - eyes move up to maximum fast) only for eyes move 60 Hz + 50 fps = with frame-to-frame only for eyes move." - should be higher Fps/Hz = better viewing - any game performance without limit: half life 2, gtr, far cry, 3dmark any year, etc. - shouldn´t be higher Fps/Hz = (nor) better viewing - any game performance with limit: sensible soccer 2006 (up to 50 fps), pes 3, 4 and 5 (60 fps), ford racing 2 (60 fps), doom 3 (60 fps - default), etc. in case of "frame-to-frame", I recommend to reduce to any (down to 50) Hz! good luck!!
