Rhino 5 slow region selection on pointcloud using new laptop

Hi all,

Just wanted to ask if anyone suffered for very slow pointcloud region selection on Rhino 5 with brand new computers? Just got new laptops at the office and was testing during the weekend how it goes. Everything goes smooth and with no issues until I tried to do a partial selection of a pointcloud.

  • In Rhino 5 it takes 3min to do a selection of just 18652 points in a pointcloud of 1.2M points. The CPU stays at 15% and after some time it does the selection.

  • Same pointcloud on RH6 on the laptop or in RH5 on my desktop computer produces and instant selection result with no waiting.

  • In OpenGL options, RH5 looks like using the QUADRO GPU.

I don’t know how to get the system information from RH5 so I extracted the content pasted below from SystemInfo in RH6:

For the sake of keeping you posted, noticed that after run a command like ExtractPt on a selection on the pointcloud, the next time that I try to select points on the PC, the selection is done instantly with no delay.

Let me know if you want me to do any other tests.
