This was the cause of the low quality of FFXIv. Yes, the game looks good, but they put all efforts on making the gme "beautiful" nad forgot about the mechanics. So yes, looks better ,but wasa aworse game. For ARR, they dedice to use a different engine (a low quality Luminous Studio, instead of the Crystal Tools from FFXIII) in order to get better performance and allow low end machines to run the game.

1.0 when released needed a very powerful machine.
