1.1.0.9 fresh install. I posted here before with the same issue and had it resolved with the graphics.cfg sync = 1 edit, however that doesn't seem to be working this time.
I just built a new computer. Asus Maximus extreme-Z, Core I7 2600K @ 4.6Ghz, 2 EVGA 580GTX's in SLI, 8GB DDR3 2133 RAM.
I did a fresh install of the latest version on my SSD, and I encountered the same issue AFTER the sync = 1 edit. I also forced VSYNC on in nvidia inspector and nvidia control panel.
What I see is subtle horizontal waves, barely noticeable a lot of the time and sometimes clearly obvious. My monitor is a LG W2340 LCD. The only time I ever encounter this issue is with the DCS A-10C, so I dowbt it is a monitor issue.
Any suggestions?
