Rhino 6.4 Slooow




Just working in 2d in Rhino 6.4 is remarkably slower than Rhino 5.
The file was drawn in Rhino 5 but I’m chocked that it’s that much slower just panning and zooming the scene.

Hei Morten,
there’s nothing for us to do here unless you post (1) your SystemInfo and (2) a model that allows us to reproduce what you see. RH6 should be faster, so clearly, there’s something going wrong on your system.

Sensitive models can be uploaded to https://www.rhino3d.com/upload/
Please provide a link to this discussion in the Comments field.


Hi Wim,

Just tried…
But I get a “server error” when uploading to the link you gave me.
Do you have an email I can send to?

It appears that you are running Rhino for Windows on a Mac… Does Bootcamp allow for a more recent video driver than your current one? The most recent appears to be from 23.05.2018…

I’m not sure what can get in the way of that - seems to be working fine here - @brian?
Morten, you can use the general tech@mcneel.com eMail address.

Sadly, that upload link seems to not work very well from some parts of the world. Perhaps you can share a dropbox or Google Drive link with us?
