A number of Dark Souls II screenshots with higher visual quality were removed from the game’s Steam Store page.
For example, the image above, which still appears on the game’s Amazon page, also appears in an Wayback Machine March 28 snapshot of the Dark Souls II Steam page. But at the moment, the Steam page features only seven screenshots released earlier this month, all of which show off graphics closer to the visual quality in the released console version of Dark Souls II.
This is a fairly strong indication that the PC version will look similar to the console versions. It will have 60fps, and support for higher screen resolutions, but don't expect better lighting.
