In 3D, it is 54-60 fps (which is not great). Switch to 2D, it is 11 fps. Perhaps this is burning CPU doing per-label Cartesian/cartographic conversions?

Just as a data point, I tried this today and my numbers were 40fps in 3D, 20fps in 2D.

Is there anything that can be moved from CPU to GPU to take some of the load off?

ETA: maybe this would be a non-issue if #5096 got sorted out?
