Augh, that's terrible. :/ Oh well, I'll see what I can do.

I should mention though, I just went in game to check out some of the new settings I changed, and the lag/stutter/sluggishness/whathaveyou is much, much worse in full-screen mode for me. All at once different sections of my screen are refreshing the image at different rates, so I've got these patches everywhere that are jittering. I'm going to try it in windowed mode again and see if that makes a difference.
