Slow rendering / hanging of EC2 instance via Remote Desktop Connection

[csherwood]

Hi,
I am having a problem with Metashape hanging or rendering so slowly it is unusable. Any manipulation in the model window (panning or rotating the sparse cloud, using F11 to go full screen) locks everything up. Similarly, shrinking the model window and restoring results in a white screen and a (Not Responding) message...the only thing that works is killing the program and restarting. Menu pull-downs are also slow, but eventually work. Actual processing seems very fast and crude benchmarks put it about 2-3 times faster than my local workstation. My connection to the EC2 is via Remote Desktop Connection and my connection (via government VPN) can be slow, but is currently 60 Mbps. Any advice would be welcomed. Is this the situation that (expensive) Teamviewer can help with?

Here is my setup:

Metashape 1.5.5 build 9097

AWS EC2 g3.8xlarge: Windows Server 2016 Datacenter 64 bit, Intel Xeon E5-2686 v4 @ 2.3 GHz, 244 GB, 1 Microsoft Display Adapter, 2 NVIDIA Tesla M60. The monitor is listed as a generic PnP monitor...not sure if that is relevant...display settings cannot be changed from a remote session.

Currently working with a project with ~3500 images and sparse cloud that started around 60M points, but has been edited to about 13M.

Thanks! Chris

Hello Chris,

Can you please post the starting lines from the Console pane related to OpenGL vendor, renderer and version?

Are you observing any similar issues with any other applications that use OpenGL on a remote machine?

Thanks for the response. The info you requested is above. I am not using any other graphics-intensive applications on the remote computer. I don't think Teamview is going to work...they route data through their servers, which will not make our IT security folks happy.

Hello Chris,

I can suggest to try running Metashape from the command line using the following parameters and check if it makes any difference:

Code: [Select]

metashape.exe --opengl software
As a test I could suggest to try using Google Earth in OpenGL and DirectX modes and see, if it navigates smoothly.
