Our workflow is now to make sure we import the point clouds in PTS format and use in Orthogonal projection, Layers set at "Show Others" to get all the colours in the point cloud. We're using VW 2020 SP2 at the moment. Most of our point cloud work is for measured building surveys for plans, sections and elevations, or parts of ships for 3D modelling, so our models are fairly small in dimensional size, rather than landscapes that are relatively larger, although we still max out on the number of points imported every time.
