Have some Leica BLK360 SE scans here. Imported via .e57
When I tumble the view with the mouse there is a strong degradation of the point cloud, which makes it very hard to work with it, like tracing lines etc.
speed is fast, so it is not a FPS depend matter. I already set this to 0.001.
any other way to suppress degradation?

hi @dk2079 can you share the file?
I sent you a DM. Let me know if that came through 
yes, I’m looking at it, thanks for sending.
I think the degradation is intentional, but not really needed in this file. The reason you don’t see this in Rhino BETA is probably because that hasn’t been implemented yet for direct3d.
@stevebaer can you advise about this?
Thanks for having a look.
Yes, the reduction would not be needed, even very large clouds with 30m+ points display absolutely fluent on my GeForce RTX 3080 mobile.
on a side note, when I was researching over the topic I found a few entries that suggest there should be a density slider for Point Clouds in the properties. But I could not find it in R8 or R9, or a mentioning about it in any docs.. mysterious!!
see here:
from the link below:
Optimizing Display Performance:
- Large point clouds can be resource-intensive. Adjust the display density to improve performance:
- Select the point cloud.
- In the Properties panel under Point Cloud, adjust the Point Density slider.
- Lower densities display fewer points but increase viewport performance.
AFAIK that info is wrong
interesting! it sounds like a good idea 
Degradation should be in Direct3d in the beta. Are you not seeing it?
latest beta:
no degradation in D3D only in OGL
please keep it that way
