One of the critical features in a triple-monitor setup in iRacing is the ability to render 3 separate "viewports", which give the center view and then two angled views (looking left and looking right). The angle of the side views is configured to match the angle of the screens. Is this functionality going to be available in rF2?
We have "MultiView" (check in rFactor 2 launcher before starting the sim. Also make sure Nvidia Surround is on) and in the sim, on track, pressing ALT+A or CTRL+A (depending on what you set it to) you bring up triple screen settings and can set bezel, distance from screens, angle of side monitors etc.
