I imagine it won't be long before Nvidia release a new driver that corrects the issue, anyhow.
I wouldn't be so sure about that. A year ago (November 2014) Nvidia released a driver that broke Dragon Age II's DX11 renderer. I don't know the current state of Geforce compatibility, but the issue was still reported here as late as August 2015.
I currently don't have a PC to test this on (my gaming PC has a Radeon R9 390), so I don't know if that has been fixed by now.

You can also try turning off MSAA in the Inquisition Graphics options. That fixed it for me. Postprocessing AA isn't as nice, but you can use it instead.
Might want to try this first, since it's a little less drastic than rolling back your drivers (as easy as that is).
For me personally, if the choice is between FXAA or no AA at all, I'd pick the latter. FXAA has no performance cost, but it's also very ugly. It removes jaggies by making the entire screen blurry.
