You do realise that FFXV runs bad even on PS4 Pro, game is not optimised and has very demanding engine, thats all.
Infos we having curently tell us that Doom is seling quite nice on Switch, so yes desipite "Sub 720p most of the time and gets down to 21 FPS in larger firefights" game is selling well and Bethesda will make profit, so yes, people are wondering why there aren't more PS4/X1 games on the Switch beacuse they can make money on those ports, but we know that much more PS4/XB1 ports are coming.
@bolded: That may have been true at first, with the bad frame pacing (while still being pretty much rock solid 30fps).
But now? Nope. The option to have the game run smoothly by selecting the Steady performance profile has been available for quite some time now and gets rid of the frame pacing issue. So yeah, the game is indeed quite optimized in its current state.
