That'd be the 'graphics problems fix' patch, when they broke the graphics of everyone else who hadn't previously been having problems, yeah. It broke most of my LOD meshes, my texture quality, and introduced pop-in and culling that they still haven't removed since.
If you've saved since, you can't revert, sadly.
I'd be tempted to suggest trying some earlier revisions of the nvidia drivers, but I know the 900 series have had some important stuff piped down lately, so that's probably not the wisest of things to do. You're at Bioware Q&A's mercy, the same as many of the rest of us, I'm afraid.
I'm presuming you've tried the easy stuff, like turning off Origin in-game with Inquisition?
