Actually I believe they should copy what P3D does. It’s the best multi-view system in my opinion, and the ViewGroup system (combined with multi-channel simulation) can offer decent performance even with many outside views. Under DX12 multi-viewport should be straightforward. P3D has had all this for years and even FSX had most of the capability natively. Triple screens is fine but it’s only the simplest use-case for multiple views and it only satisfies a small percentage of advanced user needs.
