Hi,

First, sorry for my bad english.

So, i have a problem:

I play on Windows 10
5k screen (5120)
Graphic Card : AMD Radeon Pro 580 , 8Go
Proc : i7 skylake 4.2 Ghz
Ram : 16Go DDR4
i can play in ULTRA graphics level with some recent games like MASS Effect Andromeda for example.

When i put the resolution in FF14 at 5120 and maxiums details : its unplayable. 10 img/s
??? I dont understand why???
even in LOW details i only have 30 img/s
when i put my resolution on 4k (3840) : i can play at midrange details with 30 imgs
when i put the resolution on 2555x1440 : i can play maximums details at 55 imgs/s , wich is good but not 60/s

so wtf, i think my computer is powerfull enough to play at max resolution.
if someone could help me.....
thank you
