How can i fix this issue?  
I have Revit 2020.2 with Dynamo Revit 2.3.0.8352 instaled.  
DirectX 12 (DxDiag 10.00.19041.0546)  
GTX 960 GPU with latest drivers instaled  
Procesor is i5 10600K with Intel UHD Graphics 630  
I have instaled DirectX End-User Runtimes (June 2010) from [Download DirectX End-User Runtimes (June 2010) from Official Microsoft Download Center](https://www.microsoft.com/en-us/download/details.aspx?id=8109)  
In Nvidia control panel i forced Revit to run on Nvidia GPU.

And still no background preview available.  
I also instaled Revit 2021 to check if it will work on this version of Revit but still background preview is not working.
