What is the fastest way to import a topography?

Hi all, Is there a recommendation to have a faster topography import? Assuming a similar resolution, which input is faster to import?

  • Points
  • Surface (as mesh)
  • GIS Vector data
  • Elevation grid
  • Polylines

Usually the processing get stuck for a while on the "topography interp" step.

Is there one format or or the other that is faster with a graphic card?

Is there a benchmark on processing time?

Cheers!
