Welcome to PR.........if you have ANY doubts about a game, wait until its out and see reviews and impressions from people who are actually playing it, not from Dev's.
There are 2 options that were set on LOW after i downloaded and installed the patch. Texture detail and water quality....try putting those at ultra to see.
The screenshots look great but that means absolutely nothing if the expansion looks nothing like it. I cannot trust doctored up screenshots, I must see actual game play to see if those screenshots look the same or is just more marketing BS.
Those screenshots are Photoshopped to hell most likely like all promotional shots, they are all touched up to improve detail dramatically. Been this way with promotional screenshots since forever with games.
Awe man that's disappointing, was hoping the lighting could be modded. It's a pretty major downgrade from the e3 demo in 2014 to what it is now....oh well
