Regarding FPS.

[Luke.]

I would absolutely say yes it's worth it. It smooths out the mouse so aiming becomes far less awful through much less lag and also your sense of "speed" will be better felt since it'll cause a visual effect of your ship (this mostly applies to fighter craft) swinging a lot more when you turn. There's a lot more feedback to your mouse movement basically even if it is just superficial.

Just bear in mind you cannot go above 155fps or it'll cause problems. More info on that here.
