Maybe you experienced world tilting as I did big time. This prevented me from further using DK2 with OT. It causes immediate sickness especially in fly mode and normal mode. First person cockpit mode should work better, because there is no tilting of horizon involved. Please look at my posts above. Don't know, if the next version will cure this.
Add to it low res of oculus display (and no AA in OT) and performance struggles, and you have a quite unpleasant thing.
Where OT really shines is, when you connect a hdmi1.4 stereo Monitor e.g. Asus VG278H. Fantastic!
