Hey, thanks for the reply.
I have no idea what happened to the screenshots I've posted, I definitely didn't mean them to be that way lol. Sorry about that. I edited the opening post a bit.
I attach the one that really shows what the matter seems to be. A "boring wall" is exactly what you should see, but also a boring wall that is rendered in a quality that is definitely not highest graphics Dragon Age Inquisition. It is definitely not a mod that I'm missing, and it's not that the textures aren't high resolution, they just look completely wrong. Here's a video from the very same wall I have my shot of, behind Cassandra:

THAT is how it looks by default, and it should be that way in the interiors, the fortress in Hinterlands, etc. What I have is a really bad looking mess for no reason I'm aware of. I also attach a shot of the armory nearby just in case.
I'll do a dxdiag once I updated my BIOS, that's the last I can think of but I honestly don't see if that could be it. Thanks for the hint anyway.
