Damn, I was almost ready to place an order for a Rift. It was just sounding like the Rift was outperforming the Vive on ED. Given time, and assuming VR survives (unlike 3D TVs), I'd assume the Vive would get better. But then I read about the problems people with glasses were having with the Rift. So then I was flipping back to the Vive, hoping for eventual quality improvements. But then, unless I'm mistaken (there's a lot of misinformation out there), neither the Rift nor the Vive offer a focus adjustment nor a diopter adjustment, although the both offer an IPD adjustment. I'm so fed up with this crap that I think I'll just have to wait for generation 2 and hope that they offer all three eye adjustments so you don't need to wear glasses (assuming not having more serious eye issues) at all. And hopefully generation 2 VR will be higher resolution w/o the screendoor and other side effects.
So I think maybe I'll go to 4K resolution as a stop gap. Switching from 1920x1080 to 2560x1440 was pretty amazing. Switching from 2560x1440 to 3480x2160 should be even more so. It's looking like 4K will require an GTX-1080 (or Ti), and a quick check of 32" monitors looks like they are going for $750 to $1000, so similar to a VR headset.
I think I'll do a little more research on 4K monitors and then put a couple on a watch list, along with a new video card. I may even be able to hold off on this upgrade for a Black Friday/Cyber Monday sale. So unless I hear much better performance improvements, or about better support for wearing glasses, for the VR headsets, I'll pull the trigger on 4K instead.
Damn.
