No. WoW does not use cursor/camera smoothing tied to FPS, never has. Swtor does. That's why it is a different issue. It is combined with the unnecessary mouse acceleration that Swtor forces on you, combined with the badly designed cursor feature in the game. I don't spin "180 degrees", it just turns the camera in any direction opposite of where I am looking, once in a while randomly, on top of the annoying to look at obvious mouse smoothing/acceleration that makes it feel delayed.

The other guy probably just doesn't notice the mouse acceleration, but it's definitely there. There's tons of posts about it. Even in his "related links", there's a community manager/member acknowledging the flicking/spinning portion has been there since launch - yet, it hasn't been fixed, or raw mouse input hasn't been added?
