To answer my own question, I killed those two processes.
Yanked my main monitor cable and configured VR for 1080 / 75hz / portrait.
Problem comes in that FOV for each eye is rather limited so I can't see anything outside of it. I had to peck my way to DCS icon and then to fast action...
To describe visuals. I have 55 inch monitor and if I move my face 5-7 inches from it, I will see pixels. Same with VR. But there is very strong depth perception. Everything stands out. Tracking is wonderful; it doesn't care about external light or such. But unlike with TrackIR, now its hard to look around because your neck just doesn't twist 180 degrees. Checking 6 requires movement of entire body.
More to follow....
