At 1280x960 outside (walking around right out of the sewers area) I can keep the FPS above 30 most of the time, I can even tweak the view distance settings further and keep them up above 30 or high 20's at the worst.
At 1600x1200 I can get in to the low 20's and it makes the game feel sluggish.
At 1600x1200 "jaggies" are almost a non-issue but at 1280x960 they are a little more noticeable but for the extra 6-10 fps it is worth it. It pushes the games from sluggish to smooth.
I wish there was another way for me to pick up 6-10fps without too much quality sacrifice. I'm open to tweak ideas?
