Rough estimates only, I'm not conducting an in depth analysis. Just initial impressions. I did crank up all the settings to Ultra and it was indeed quite punishing. However, just as in Crysis 3, if you back off just a bit on some of the post-processing, the game doesn't lose much visual eye candy at all. Also with over 5 hrs in so far I've experienced no glitching or crashes-- I believe Ubisoft cashed all their chips in on this game to make it as polished as possible. Unity got the short end of the stick =P.
