Sorry for my bad german. Here it is: "ULTRA" SSAO setting stands for HDAO, wich is AMD's form of ambient occlusion and causes a big performance loss on Nvidia cards. But even with an AMD card you should NOT set this game's graphics to its maximum settings, you should set "SSAO" setting to "NORMAL", because "ULTRA" stands for HDAO, and "NORMAL" stands for SSAO, that makes a bigger difference, does have bigger shadow casts and more objects seems to be affected, even causing a smaller performance loss. http://wiki.gametrailers.com/viewtopic.php?f=13&t=1347403&start=40 http://www.hardocp.com/article/2013/03/20/tomb_raider_video_card_performance_iq_review/8#.U9mBmrHQr2o
And set "HIGH PRECISION" option off, because it does not make any (i (and some people on the internet) did a screenshot comparison and i saw no difference) noticeable graphical difference, even causing a HUGE performance loss.
