I meant the resolution you've chosen in the screensaver (in "Settings")--such as 1024X768 vs. the resolution you have your monitor set for, such as 1200X1600. I honestly don't know how much of an effect, if any, it will have on FPS, but it couldn't hurt.
Someone else can define V-synch better than me. It basically has something to do with allowing the photon gun in the monitor to spray out a full frame, line by line, before moving on to the next. Hence there is no appearance of tearing, and the animation runs more smoothly. Right, guys? Close?
