I had posted this on the Steam Forums. Your input please. I was running both monitors in extended the desktop configuration from the ASUS 1060 6Gb GPU and getting frame rates averaging in the 40s to 50s. In the game configuration settings, it listed the screen size as 3840 x 1080. I read an article and it suggested running the desktop on the graphics driver off the motherboard. I enabled the internal graphics through the bios (it is disabled by default when a discrete graphics card is installed). In Windows it still is set to extend the desktop but while running TSW and CSX HH frame rates are in the high 50s and occasionally in the 70s. the configuration shows 1920 x 1080. Those running dual monitors may give this a try to see if it helps.
