Okay I just watched the video. I have good news and bad news.
Bad news first, that looks to be Divinity 2 with 1.02
And if you really look, the
shadow has problems right now. Notice that
weapons didn't cast any shadows (and that is on highest setting for shadow). Also, as I mentioned in my post,
your summons does NOT cast any shadow either.

Also, the "zoomed" in version of the books does look pretty blurry.
Now, the good news.
That video does not look like it is recorded on higher graphic settings.
I just ran my character through similar location, and I can tell you that the smoke particles has much "softer" effect in my game. (Also, in my game, the fire that comes out of gargolyes has a much more extend and "rolling" effect, giving you are in a freezer kinda vibe).
Textures in my game are more detailed, also they react to lighting much more. For example, my character's equipments are shiny and the shininess depends on the lighting.
Also, the "zoomed out" view of the the books have much more detailed textures too.
TBH, I am very picky when it comes to graphics, and I don't think that video did a good job to showcase the graphics of the game. Maybe I should record something...
