I was using the Rift S up to about a month and a half ago. As I literally said, I was still playing Pavlov and Contractors on these new updates that fixed the issue and I still had it on occasion (although I'm sure it's better than it was at launch). The software updates actually made my experience worse - Was getting constant crashing after April or so.

Re: FOV the Rift still has a limit as to how close it can get to your face and the Index can get a lot closer. The FOV increase is very noticeable at close range shooting, and the extra bit of resolution does a lot to mitigate SDE which is good for long range engagements. 

The tracking basically updates at 60Hz on the Rift S quest, but it splits those tracking updates in two - Half of them it uses only to get tracking data for the HMD itself, and the other half it uses to get tracking data for the two controllers. So you get 30 updates per second for the HMD, and 30 for the controllers - 30Hz individually for the two items.
