I'm having a similar issue with the latest beta version -> just downloaded and installed it. The previous version(s?) had the same issue.
If I select a VRay camera and set it to limit to visible items, nothing is showing up in the viewport AND also nothing gets rendered. The stats tell me "N/A" for all entries.
Even though I understand working with a beta means taking a risk, this was still really frustrating since I'm on a very tight deadline atm and it took me a while to figure out the camera limit visibilty was the issue. Plus I had to go through dozens of Forest objects to disable limit visibility... older versions never had this issue.
The weird thing is, it worked fine up until a certain point. Maybe things went wrong when the total number of items got above a certain treshold? I don't know. All I know is that I need to disable this option
