Same here ... I kinda expected there would be problems on Day 1.
Millions of people trying to download 90 Gb at the same time was sure to cause bottlenecks.
I also prefer to read reviews before buying ... from what I've gathered so far, there are problems with CH devices (yokes, pedals, etc) and there is no multi-monitor support (as of yet at least).
Those are deal breakers for me, I'll stay with X-Plane 11 until those issues are resolved.
