Hello Windranger,
Your description is quite vague. In order to understand this better I would like some more information from you.
1.) Can you link me a copy of your DxDiag?
2.) Is this your own blank project or one created from a template?
3.) Is this version of Unreal from the launcher on Epic’s site or from GitHub?
4.) Is this a project copied from 4.8 to 4.9?
After I have this information I will be able to assist you further.
- my own blank project
- from epic launcer v4.9.2
- from 4.9 to 4.9.2
