3d View not available

I am not getting any visualization for dynamo, only an empty grid I can zoom in and out. I am using Revit 2020.2 and dynamo 2.3.0 I heard that it had something to do with the graphics, I tried to change the graphic card in the Nvidia control panel for Revit, but it doesnt let me. any suggestions?

Looks like you haven’t enabled the preview.

Check about 30 seconds into this video: https://m.youtube.com/watch?v=tTpqBBnfVh8

Hello, thank you for your answer, I do have the preview enabled, and following the other suggestions in the video, my DirectX is the latest version (12) and my graphics card is NVIDIA I have tried it with the High Performance NVIDIA processor and the integrated graphics

Found the solution, I looked in Dynamo’s commandline and I got an error:
Unable to find [sharpdx_direct3d11_effects_x64.dll] in the PATH
I searched in the forums, found a suggestion to install DirectX End-User Runtimes (June 2010)
I installed it and is working fine.
