Here are my settings, they work for me, but then again im a little bit special. Water reflection detail, well you wont need that at 30 thousand feet up, its not that good anyway. I keep mine at 0 Shadow detail, I keep mine at 0, never really seen the difference. I presume you have Real Terra Haze? Fantastic plug in, If not get rid of HDR, its a killer. Stuff to draw, keep it at default setting, unless your flying low or have the eyes of a hawk Uncheck "Run fullscreen at his resolution" Pump up the gamma to 2.8 or what ever suits you, I find it better. I only turn up the eye candy when im flying small and low When im flying high i turn off everything and leave Texture resolution at Extreme i7-3930K 16gig GTX690 4gigVram
