Hey i picked up a dk2 from a good friend who used it for mostly sim racing. Installed the 1.3.0 sdk and it was up and running and working just dandy. I tried to play a game from steam on the vr headset and everything crashed. pulled up the rift and the head tracking is now very buggy even after uninstalling and re downloading everything. when im sitting with the rift on it it has a lot of judder, even rubber banding to the point where im seeing object that were behind me flash in front of me momentarily. How ever when i stand up these issues mostly go away. What in the hell is going on here. how do i resolve this.
