Just throwing this out there for the developers. I just finished Getting to Know ArcGIS Pro. Chapter 8 deals with rendering temporal data in 3D. While browsing the map to review the 3D layers, ArcGIS Pro was using 12 GB of system memory. I thought that seemed a bit high. I'm using a Dell OptiPlex 7010, which isn't the mightiest of computers, and maybe this wouldn't be an issue if I had a better graphics card. Either way it may be something to look into. Thanks.
