Using a 2005fpw, I noticed in HL2 when I moved the mouse around the menu it looked a bit choppy, so I went into the options and changed the refresh rate from 60 to 75, and the choppiness wasn't as bad. I would like to do the same thing for windows but it doesn't let me bump it up above 60. I've read in different forums that LCD's can't go above 60, is this true? If so, what was the enhancement in HL2 I was experiencing? I run windows and HL2 at 1680x1050.
