Adding on too, no everything else is totally responsive all the time when its doing this not. I don't notice a frame rate drop, it's just the models seem to be appearing to shake. I noticed it originally on an app I was making that sent an airplane over the users head, and I noticed sometimes it would look great and sometimes it would be doing this.

First of all thanks for trying to help. I re-uploaded my code to show it better with more cubes, but when I say lag/choppy, I mean when you look at the edges of the model, it appears to be shaking at the edges. Like try to focus your eyes on the edge of it when it passes over, it almost hurts your eyes trying to focus on it because it's flickering back and forth. Did you compare it to opening it in mixed with no immersion on at all?
