I have no experience with the DK1 but I got my DK2 about a week ago. It took me a while to figure out how to get it working with DCS but I did. It depends on your system because a lot of people have different experiences. Mine was not a good one, all of the other DK2 demos work real nice for me but for some reason DCS is real jittery. I turned all the graphics detail to low, I'm running on I5 2500K with 2 GTX 760's, I haven't tried turning off SLI but thats the next thing on my list. Even if it was smooth, its hard to make out the details in the cockpit such as the dials and knobs which makes playing it as a simulator damn near impossible. I know this sounds negative but the Rift is definitely cool. I played elite dangerous in it which worked fine for me and it was the shit! The asteroids had mass and being able to track enemies was awesome. (I don't have trackir) It definitely felt really cool. If you are on the fence on getting one I would wait for the CV1 because the DK2 does have its problems. The resolution is low so everything is a bit blurry so you can't really see things that are far. It does get a bit uncomfortable after a while, having it on your head. Trying to figure out how to open programs is a pain. You really should only get one if you are a developer, I just couldn't wait because I was so excited about VR and I still am but I don't think its quite there yet but it will be. I am loving DCS but I don't want to shell out 150 for TrackIR after I just bought the rift. Its been a while since I've checked out the sim scene, thank God it is still alive and kicking! So much more information these days, it was damn near impossible to land the F-16 in falcon 4.0 when I was 16 with no resources with no patches. If you want to know more about DK2 just hit me up!
