Assetto Corsa Competizione runs on triple screen setups as a single render scene, that is split over three displays. The game features a special projection correction that reduces the lateral distortion that might affect ultrawide screens and triple monitor setups. (It’s called Pannini Projection in honor of the Italian painter who invented it in the 18th century). This feature can be set in-game in the “view settings” option. We appreciate that some users are requesting three separate renderings in order to tune bezel values and screen angles. Currently, Unreal Engine 4 doesn’t support this feature. We’ll continue to investigate to see if in future the triple-separate rendering will be supported in a feasible way.
