Having low latency, no frames dropped running natively is hard. Exceptionally hard. One of the biggest issues is actually drivers and the near infinite number of hardware permutations. It's still a major issue with the SDK. Now let's add a super heavy, bloated web browser in between the OS and pixels. I've yet to play any decent WebGL demo that didn't have minor hitches or dropped frames. VR is merciless. You need to make your frame 100% of the time or it's a majorly jarring issue.
