Well, the new TE hasn't been out a week and we're already in patch 3. I suspect there will be several more patches over the next month as issues are revealed along with repeatable descriptions of the problems. I've watched this company for a long time, and there's no one that takes better care of their customers then htc, give them a little time.
This isn't a criticism of anyone. Some of us have the time to test things in the game, and some don't but those who can't will have to wait until someone with similar hardware comes along to provide enough information to help solve the problem. The beta presented many of us the opportunity to learn something about the new game engine, and provide details on the experience and our hardware. I participated, posted dxdiag data on my rig and a description of how it was running poorly.
I don't believe it's an accident that the game is playable on my hardware. I saw fewer then 5 people in the beta last week, so I concluded that it was either working, or that the only way to gather more responses was to go live and "fix it" after the players started supplying the needed feedback in the form of dxdiag, and reproducible issue reports. It's hard for me to imagine how frustrated they must still be after the lack of participation and feed back in the beta. I see lots of threads about problems, but not to many dxdiag reports are accompanying them.
