Render Quality Lower Than Real-Time

I'm having an issue with LumenRT thinning out the trees when photo or video rendering the model. However, in real time, the full tree models are shown. 

Real time:   Rendered: 

In the renders, it looks as though the trees are just trunks and branches with no leaves/needles.  It doesn't matter what quality setting I set the renders to, the result is the same. I could see this being a hardware limitation, as the machine this is running on uses a Quadro P1000, but it doesn't make sense to me that it can display the full models in real time without  a hiccup, yet fails to render them.  A screen shot of the model looks better than using LumenRTs renderer at this point.

Thanks for any help,

David
