I just went through all my settings again in Beta, hoping that maybe I missed soemthing yesterday, but came up with same result. Beta graphics in VR are nowehere near as good as in main release. They defo look low res, blurry, and very dated in comparison.
I have tried in game SS, Nvidia DSR, SweetFX, etc all multiple times with no change. Everything I do makes no difference. I guess we just need to report and wait, see what happens. I'm sure they'll come up with a fix in due course for whatever is causing it. I do find it odd though that some people are claiming it's looking better :S Perhaps they played in low res anyway? I dunno..
I have DSR set at 2560x1440 in beta, and although it looks low res and crap outside the cockpit (stars,planets,stations), inside isn't too bad and is very smooth at least, still nothing like the full game though.

My OR is set to secondary window. The only thing I haven't tried is setting it to Primary, which I've planned to do for a while now anyway so might try that later if I have time.

EDIT: Personally, I think it's great that you guys are speaking up about your beta experience in VR, as I'm pretty sure it's a huge and important part of what FD wants to get right, especially during Beta. Isn't that what the VR discussion and support forum is all about - Giving feedback, raising concerns, giving praise, sharing knowledge etc etc. I'm fairly certain FD appreciate all these concerns being raised and wouldn't want you to keep quiet. Just my 2cents..
