Its been a week that im searching a solution to my problem and yet I only found this guy who got a problem that looks similar to mine (but my ''shaking'' is a little bit less pronounced, more subtle, but still very annoying) https://www.youtube.com/watch?v=7PJnxZ6A1p4
. Take note that even when Im not moving my head, what is displayed on the screen shake like that.
This problem seems to comes on and off no matter how I setup my DK2 (direct mode, extended mod primary monitor with my normal monitor on or off), sometimes it will be there when I launch any demo, sometimes it will start perfectly, no shaking, and then, some seconds after, it begins. The ''shaking'' is constant (all the screen is shaking, no matter if I stand still or not) after it begins until I put my hand in front of the camera to loose all tracking with the rift, then the shaking stop. After I remove my hand my tracking is perfect again, my vision is not shaking, everything works perfectly... but only for a couple seconds (around 15-20 seconds) until the issue comes again.
It seems to be only relied to positional tracking with the camera. And I want to point out that my camera is on a completely stable surface (i even bought a tripod thinking it was the problem). My firmware is also updated.
Thank you for your help. :?
EDIT: SOLVED. Had to plug in the power adapter. Seems like the usb camera was not getting enough juice from my computer.
