Oculus 1.3
As a dk2 user I can honestly say this has made a huge difference. I mainly fly the huey and as well as performance improvements the cockpit also seems to be easier on the eye. Can't wait for nevada to get the upgrade and someway of getting kneeboards, radio menu, and missions easier to read. May even move from just enjoying the flying experience to doing some missions. If you haven't yet tried DCS in VR then you really are missing out. Of course just my opinion :)
