The last game is Cities Skylines, which incidentally has its own high-res screenshot feature. Otherwise you have to rely on 3rd party tools, eg Nvidia Ansel. Yes, steam ones are at the res you play. As for quality when uploading, usually there's compression involved, the end result will depend on the site you upload to. If you want to present the highest quality screenshots, I'd suggest using flickr.What games are those in the last two posts? Also noob question, how do I take hi res screenshots? Are the default ones in steam taken at the res you play? Don't they lose quality when you upload them somewhere?
Edit: Oh I see Evil Within.
