Really annoying input lag
 

I'm having this really nearly game-breaking issue where there is a slight bit of input lag when playing the game. This effects joystick movements, mouse movement, and everything else basically making it damn near impossible to pull of precise maneuvers, especially when the enemy is flying all over your screen.

My FPS is solid, but the input lag is killing this game. Is anyone else having this issue?

I even notice that when I bring up a Steam chat window and type there is a delayed response from my keyboard to the text. It's reeeally annoying.
