FYI, there is an NIVIDIA GPU driver known issue starting with 530.xx and fixed in 535.xx.

Additional information: ChiefDelphi

If you are experiencing the issue where the shading is missing and the model looks rendering outlines only like this:

To resolve this issue:

• Please rollback your driver to a version older than 530 or update to 535.xx or newer.

Additionally, there are a couple of possible workarounds if the driver update is an issue:

• Disable “Optimize for thin parts” in the display options

OR

• Disable “Enhance Graphics Performance” in Performance options
