When the Game was sold to us on the Kickstarter it was sold to many of us that it would support the Oculus. An Oculus that was still in Beta. So quite a few of us bought into this.
So, they were selling some of us something on the back of a product that was in beta. Ok. So, it's going to be upgraded. It's going to obviously be unstable, and it's not unreasonable to expect people also upgrade the beta product as time goes.
I keep hearing how easy it was for them, almost minutes, to add in the version of VR support they currently have for the Oculus. However, there seems to be some great difficulty in getting the later versions in. This feels like it was a great hack to get the initial version in there. Slap the code in, "meh, it works, that'll do" kind of attitude, forget about it and ignore everyone who is now complaining, who is actually trying to use the Oculus for, I don't know, other things.
The same problem with Windows 10. It's not like there was any kind of warning it was coming or anything... none at all, it just appeared magically on our machines one day. I was as shocked as everyone else. (sorry about the sarcasm).
Either the devs have actually stopped development altogether on VR, or they just don't actually feel like they owe the people who actually paid them money for it any more.
It IS their responsibility to fix the issue with the development kit, Darkmark, they linked the Beta libraries into their code and failed to maintain it when things changed.
