[2022] Missing ship size Localization Key, Error create vertices and indices, and Couldn't create a render target texture

Has the game ever worked properly on this machine? Or never yet?

DXDIAG is a program you run from the Windows search box on the task bar. After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.

Have you undone this? Doing that causes problems of its own.

No clear reason for this in that dxdiag, but lets get the AMD driver up to date:

- uninstall it with this https://support.amd.com/en-us/kb-articles/Pages/AMD-Clean-Uninstall-Utility.aspx
- reboot
- install the latest from here http://support.amd.com/en-us/download
- reboot again

Does that help, or change anything?  

Sorry, I missed you have a mixed AMD/nVidia setup! Very unusual.

The game is of course trying to run on the nVidia. In the nVidia control panel, Manage 3D settings, force stellaris.exe onto the AMD option there (just as a test of course). Does that change things?  

Wow, that's unexpected! My best guess is an issue with the nVidia driver or card selection utility.

Glad we got there!
