laststop311, some people can see the flicker past 60. 60 works for me because I can barely see the flicker. I find that it bothers me more when I go to bed at night. I still see the flickering even with my eyes closed. However, when I am working with a monitor with a higher refresh, I have less problems. So, I am going to go with meowmix44 on this one. I think I top out at about 70 to 75 though, but doubling it should be nice and smooth.
