Fallout New Vegas no menu

I know the no menu thing is a known bug but I cannot for the life of me figure out how to solve it.

I used the web installer for the Steam version, everything ran flawlessly. The menu is there just not being rendered. I’ve started a new game (figuring out the button locations) and it works fine until the cut scene ends then nothing comprehensible is rendered.

I’ve even installed just vanilla NV from the steam runner and it’s the same, so I’m certain it’s nothing to do with the installer.
