If you’re debating whether to migrate a project to 2016 these posts from ‘The Factory’ may help the decision. A look at how Revit 2016 uses multicore processing to improve model navigation.
Often the Revit product team is asked how the Revit product line takes advantage of multiple processors and the workstation GPU, so we thought we'd provide a list for your reference, and a video that shows a new feature of Revit 2016 that uses multiple processors to accelerate model navigation to speeds comparable to the Navisworks 2016 model.
This post has some useful comparisons between 2014, 2015 and 2016 with the same file;
Sasha Crotty, the Revit Platform Product Manager, read the "Part 1" post and made up a video to show the multiple processor utilization in view navigation.
After that, she worked with Scott Blouin in QA to come up with some simple speed comparison charts for multiple Revit versions from our internal testing. As always, your mileage may vary,
