FF14 is basically unplayable at resolutions below 1080p. There’s simply not enough pixels to display all the detail needed for serious play e.g. hotbars, buff/debuff bars, target/focus target, party list, castbars and enough empty screen space to see the boss. It’s also complete ass trying to raid at below 50-60fps. If your framerate is low enough it starts to become a dps loss since the time you can queue your next skill is delayed until the next frame is drawn, effectively increasing your global cooldown. On top of that no access to 3rd party programs on PC that would help alleviate these issues e.g. framerate locking, zoomhacks. Only way this works out is that the new nintendo switch is a 1080p+ 60fps+ capable machine with specs equivalent to a midrange PC from 3-4 years ago. Or Yoshida is talking out of his ass giving a japanese PR response, which is pretty typical
Any time they give a reason that there’s some technical thing they can’t accomplish, just remember mahjong. The devs programmed a fucking mahjong client into FFXIV (and it’s quite a good one too, on top of being free trial accessible, apparently some people get the free trial primarily for mahjong). If they have the technology and budget to do something as irrelevant and orthogonal as that, they can put in anything (as long as the devs are interested in making it). So basically it’s all bs, plus there are mods and plugins that do every QoL and visual upgrade imaginable already implemented as a third party tool.
