Files from other PC do open extremly slowly

I’m in a new office and working with my rhino 7 license and vray 5.

I got a brand new AMD Ryzen 9 5900x, 64gig ram, nvidia 3060, m2 harddisk.

however: I can’t open files of my collegue, working with a much slower pc.
Rhino opens, but the working space stays black. sometimes, after 20min, a file opens.
file size is between 50-200mb - regular content. no plugins.

When I create a new file and draw something and save it and open it, it opens in 1 second.
I tried the files on network and local.
Is it possible, that it lags, because it is searching all the textures in the network - and I might not have the permission to access them (I should have the permission…but this is the only thing, I can think of)

I can draw a simple polyline and save it on my collegues pc - and it will open on my pc.
as I said the other files are not very big or complicated either…

Any idea?

Hi Günter -
Does it make a difference if you disable V-Ray and restart Rhino?
Can you post a sample of a file that takes a long time to open on your system? If you need to keep the file confidential, you can upload it here - Rhino - Upload to Support - make sure to mention this thread in the comments field.
Also, please run the Rhino SystemInfo command and copy-paste the result here.

thank you for your help!
there is no difference - I deinstalled rhino and vray.
Installed rhino and tried to open…same
and then again with vray…

I’m just uploading the file to your support

this is my system info (forgot to place it in the support-field)
