Segmentation in Slicer extremely slow when using the Scissors tool in slice view

Yes. The Vormela scan is openly available online and can be found at the following link…

That said, the problem is not unique to this scan but I have had it with multiple CT datasets downloaded from MorphoSource. I had similar issues with this scan of Mungotictis decimlineata, for example. Indeed, this has been a problem with almost every dataset I have loaded into 3D Slicer except for very small ones.

For the first computer it is…

Computer - Dell Precision 5820 Tower
Software OS - Windows 10
Total RAM - 32 gB
CPU - Intel(R) Xeon(R) W-2225 CPU @ 4.10 gHz
GPU - NVIDIA RTX A4500
64 bit operating system, 4 cores

For the second (the one with Avizo 7 and the one where Slicer took 28 seconds to work per action) it is…

Computer - Dell Precision 7710
Software OS - Windows 10 Pro
Total RAM - 64 gB
CPU - Intel(R) Xeon(R) CPU E3-1505M v5 @ 2.80 gHz
GPU - NVIDIA Quadro M3000M
