I just want a FF11 modern game.

[Nero-Voidstails]

FFXI at 1440p (with super-sampling, so effectively running at 5120x2880) at 60 FPS in a busy area with a lot of players, with ReShade and some other things to improve graphics, sits at about 20% GPU load for me. In a lower resolution in windowed mode without any fancy graphics stuff, it's 1-3%.

I imagine it would run on integrated graphics at 1080p with no super-sampling. There's a 14 day free trial, so you could always download it and see.

Edit: Also, if you do decide to try the game out, when it comes to choosing a server, I'd highly recommend Bahamut. Asura is very highly populated but has a lot of problems with mercs and RMT. Bahamut is the 2nd most populated server and merc culture does not exist there. Odin is also very well populated but most of the playerbase there is JP. The other servers are very low population.

then I have to try that out!
