Can you fix movement please?

I just purchased the closed beta access today and im absolutely loving this game, except all day the game has given me headaches. I havent understood why until I noticed how awkard the movement is. When I was standing still my head wasnt hurting me, but then when I began to walk around the movement is so awkard that it literally gives me a headache. I think it has something to do with my brain not comprehending the movement. I would much rather changing directions being an instant movement, similar to diablo or torchlight. I dont want this to be anything about either of those 2 games unless it has to do with the movement. Please change this as soon as possible, it really does give me a headache when I play, im not trying to exagerate or anything.

I dont mean that I see a delay, I see my character turning left/right in an awkward way compared to how often she takes a step. It looks like walking and turning are so out of sync, like its taking steps, and kinda sliding left and right. I have tried changing every setting as well, its not settings at all. Thank you for your help
