Pointless.
Compared to earlier in game demos the graphics are lesser, Not as rich.
Unless you are blind it's easy to see.
Pointless if you don't read the article and the fact no one here knows how game development works. SPS is really the only qualified one to talk about this.. along with the person interviewed in the article. If you read it-
"They look totally different because at the time we were using a very old shader system. It wasn't this physically based shader with all the reflections and the shining metals and everything. It was very -- it was a little bit flatter. Some things were very sharp, or too sharp even. We had some problems with the vegetation that they had a sharpening filter that didn't work. After a while it was uncomfortable for the eyes. It's very hard to describe. When walking through the forest very sharp vegetation was terrible. So we changed the whole shader system, we put in the PBR (he did not clarify what it was) system. Then one year later we did this 35-minute demo in Novigrad.. (muffled) demo and so on walking through the forest. And it just keeps getting nicer and nicer. It's one of the most beautiful games ever made, probably."
That explains it really, along with the fact that he says this- which people overlook.
"There also something that people probably have to understand, is that it's very unfair to compare trailers and gameplay demos. A trailer is a beautiful shot. A trailer is this prepared -- you take one location, you put the perfect lights and the perfect camera angle and the perfect set-up. It looks set-up so it is beautiful and it is captured at super high definition and you post-process it and -- it's a trailer. It's a trailer and we pick beautiful shots." A demo is not a trailer. Cannot be compared, yet everyone is anyways. Even if you compare gameplay demo's, just the first quote alone explains everything.
I'm not blind. I already knew they changed something to do with the lightning system, it was clearly different. The only blind people are the ones who know nothing of game development and just rage at something and accuse of making it worse when they really just changed something. Even if the kept the "better version" he implies it would not have been very optimised, as they changed render techniques to make it better(to them it's better, i won't argue, they know more than i do) and better optimization. Would you rather have shitty optimization or slightly "worse" visuals? Ya not a hard thing to choose on.
