Friday's release of Oculus' v0.7 runtime is incompatible with the vast majority of existing Oculus DK2 titles, as well as VROOM: Aerie. You may want to hold off a bit before upgrading.

I'm almost done building a new version that is compatible, but am waiting on Unity to release a patch that fully supports the new Oculus driver functionality. (Currently, Unity performance with Oculus v0.7 is sluggish and buggy.)

It shouldn't be a long wait; just a few days?

Meantime, I've found a way to do much smoother/faster video playback using virtually any available codec/format. 1080p MKVs now play nicely at 75 FPS, and resuming where you left off is now possible. The downside is that it only works with local content, so there's no more network streaming. Unless there are objections, I'll be switching to this method, as it makes watching full-length movies and TV shows a lot more enjoyable. I look forward to releasing it with the next version.
