bump. i'm having mouse issues as well. camera seems laggy. my fps is fine (60-70). and its not just the camera. if i click a skill from my bars and drag it around, the skill icon lags noticeably behind my cursor. but not in a choppy way. its like there's a input delay or something. very annoying. EDIT: its definitely tied to framerate. i'm currently in a room where i can face one corner of the room and get around 90 fps. the camera doesn't lag very much there. but if i face the other corner, the fps drops to about 30, and the camera is noticeable slower.
