You're talking about computer RAM or video RAM!?.


My FFXIV uses less than 1.5 GB of computer RAM and around 4 GB of video RAM, all that at 4K resolution and max graphics settings.


I agree that the game is getting really old in 2020, the best looking games use way more 4 GB of video RAM, sadly FFXIV is tied to Sony's latest console and so there's no way to expect a big upgrade, Square Enix will always adapt to the current PlayStation.


The upcoming PS5 should dictate the new standards for this game, if said console has more that 8 GB of RAM/VRAM we could see a nice upgrade in graphics; I remember Yoshida saying he would the PS5 to give better dyeing palettes, the time has come and I will not accept any excuses now.
