I am confused on what are you talking about, because this a a thread about The Witcher 3 of Switch and PS4 comparison based on Digital Foundry. I am confused on how you can make a fast conclusion if you have not watched the videos.
Because I have played the Witcher 3 on my ps4 and I have seen gameplay videos of the Switch version... I was able to do my own comparison and form my own independent thoughts. The latter part of my post maybe confusing, let me know if you require any additional assistance.
For the record I don't own any ports on the Switch and prefer games on my ps4 for the better graphics. So your defensive nature is even more baffling.
