Not for me!  I can't stand CRTs running at less than about 65Hz because I *can* see the flicker - and it's 
much worse when I look away and see it in peripheral vision.  And here we have 50Hz mains, and it happens 
whether there are lights on or not.  Upping the refresh rate to 70Hz stops the problem.
