A couple years ago, I put together a post on how to make your Bluebeam faster. It has since turned into my number one post. So it thought I should spend a few minutes updating the post for Bluebeam 2018. My understanding is that this should be a lot better in Bluebeam 2019.
From what I have seen is that Bluebeam's default preferences (the render setting) are supposed to make viewing faster, but typically slows it down. By changing your rendering settings in preferences, you can increase the speed at which your pages typically load. See below for details how to update your preferences. I have also included a couple other preferences changes I recommend.

Take some time to try out difference preferences to make Bluebeam work the best for you.
