Some thoughts on graphics without delving into downgrade too much because I don't think there is any - just "compromise":
* Dynamic lighting in certain circumstances can make assets look quite bland and 2dimensional (game will not always look 100% perfect, but we have dynamic lighting now, that's a plus.)
* Water looks too clean, even a swampy areas - it doesn't have any overlay texure for simulating some fallen leaves or other shit floating on the top (like in the our beloved VGX trailer). It's too transparent and plasticky. Also as cool as water tesselation effects are - they sometimes seem too unnatural - seems like a water is some gel substance. Also, it does not have transparency when you rise to the surface. I can say it looks stunning, but not natural at all...
* My thoughts on foliage is - they went for quantity instead of quality - the wind simulation, density, diversity, naturalism really makes the difference (I love it!). The Witcher 3 world seems natural in this aspect. It really amazes me. ... On the other hand, when you see some assets up close, they are just sprites or close to that. Also low resolution. I don't know if it is some oversight or just common sense (meaning hardware limitations), but there are games that make this much better (no and I don't think that foliage in W1 look better - far from it). DA:I looked quite nice, but it WAS STATIC!
* There are other possible visual problems in this game (latest trailer for example) which I will not discuss now because I don't have time for all that, but overall impression is very good. Judging from videos and screenshots the game looks fantastic but when you notice some deatails it is quite confusing. The material is very inconsistent. Something is obviously cut from the game, some things are "downgraded", some compromises are made. I am okay with that. We are only at the beginning of this journey - patches, mods, tweaks will follow - Skyrim is a good example of that being what it is - a sandbox game - unfinished as it was. And I am only talking about graphics now. Reds will nail the story - I am 99% confident, they will nail mechanics somewhat and overall feeling - the immersion, but there is always a place for improvement of graphics.
The GAME looks incredibly promising BTW. I can't wait to push START button
on my beefed PC. ... Then I will judge.
Oh, and I just forgot to mention tha character faces (models, shaders, animations) really does look incredible. It also applies to monsters. It will be a good, good game (with it's faults), but still it will be one of THE BEST!
