I’ve had a mixed experience using the Nvidia GTX 980 card in Navisworks and Revit, but I have one particular tip that helped in Navisworks 2017:
Turn OFF CPU Occlusion Culling

My CPU is an i7-6700K that I generally OC to 4ghz. But obviously there is some slowdown when both of the Occlusion Culling boxes are ticked.

Aside from the usual tips of using ‘Guarantee Frame Rate’, Automatic Clipping Planes, and playing around with the File Options – Frame Rate, I found that turning off CPU Occlusion Culling and leaving GPU Occlusion Culling on made a real difference for the better.

Here’s how you can get the new ‘Channels’ to show up in Unifi so you can immediately start using all of this free, new content:

  1. Ensure you are running Unifi Desktop app version 2.2 or newer.
  2. Log in at Log In : UNIFI Portal (you will have to be an admin)
  3. Click on Subscriptions
  4. Click on ‘Subscribe’ next to the Channel you want to use

  5.  Flick the switch to allow user groups to have access

  6. Back in the Unifi Desktop App… we can now search across the newly added channel

This shows how the ability of Unifi to search across channels and libraries is quite powerful indeed…

Just right-click on any content to Copy it to one of your own libraries (if you want to edit or add extra shared parameters):
