- There are issues caused by old graphics cards or drivers that NI doesn't have any influence on - so go and update your stuff
- Then there are some problems that cause crashes when unplugging, juggling instances etc. and although those might as well be related to 3rd party issues, the solution might come with an update
- Plus there are usually a handful of smaller issues (like in any first release) that will most likely be brushed out with a hotfix soon.
Here's the official thread, actively monitored, post your configuration there if you have issues:
