What exactly do you mean by the "DX mode toggle is only available when there is no driver at all?" Are you not able to select directx 9 mode on the launcher?
This means that whenever a graphic driver isn`t installed (like after running DDU), the toggle between dx9 and dx11 is available.
When toggle is greyed out - I`m stuck at dx9, which gives me a corresponding error.

UPD: FOUND A SOLUTION
At the time when I updated my driver, I also loaded newest version of Duet Display, which I use to add a second monitor. Version was 1.5.1.4b. This morning I decided what if I delete it and give it a try. Tried that and OOPS: everyithing works. So I guess I will downgrade this program a little (cause I can`t stop using it, huh) and write to their support too. Also a useful information for anyone who use it too.
