_Emap (v5 Fast) vs (v7 slow)

When using _Emap, v5 rotates the screen very smoothly, but v7 is very slow or turns into a transparent box when rotated. Can you modify it to work as fast as v5?

Hello -

Please run the SystemInfo command in Rhino and copy/paste the results here.

Rhino5 EMap (No transparent box phenomenon under pleasant screen change)

Rhino7 EMap (Shown as a transparent box after a slow frame)

I am curious about the processing status.

Hello - all I am getting are more copies of the video that shows the problem you are asking about. What I need the the Rhino 3dm file.


The same hitch appears in all 3dm files.
rhino7 is wrong.
Open each file and compare it like the Rhino 5 and Rhino 7 video (the more complex the file, the clearer the difference between the two versions.)

Obviously not everyone is seeing this, so they need an actual file to look at to even begin to diagnose it. Given your video card V7 should be exponentially faster than V5.
