4k issues

[Xoriam]

The only issue I have with the UI at 4k is the mouse not clicking things in the correct spot.

I just wanted to let others know how this game performs under 4k as I do have a 4k monitor, and to give others a bit of insight on hardware requirements to run FFXIV at 4k.

My System Specs:
i5-4670 @ 3.8GHz
32GB G.Skill Trident 2400MHz RAM (for the lulz and messing with RAM drives)
Samsung 840 Pro SSD
28" ASUS PB287Q Monitor (4k)

As for my video cards.....

2x AMD R9 280x
I was using these, but I had slow-down issues with certain graphical effects only when crossfire was enabled. Others have reported this too on crossfire and SLI, and it has to do with the purple glow by entrances/exits to boss fights.

Crossfire only work if you're running full-screen.

Crossfire messes up if you have DPI scaling enabled in Windows. If you alt-tab or quit out of the game, Crossfire will be disabled from the game until you rename the game folder (WHY? I dunno, it just does). Something to keep in mind if you run your desktop at 3840x2160.

I found that if I set the desktop to 1920x1080 there was a slight increase to FPS (mostly noticeable in Mor Dhona as I use v-sync)

EVGA GTX 980 SuperClocked Edition
After doing a bit of research, I went out and purchased this last night and it works at about the same performance as the two R9 280X I had crossfired, if not a little better and without the slow-down problem mentioned above.

There doesn't appear to be any gains with the desktop resolution set at 1920x1080.

Graphical Settings:

AA: Off (it's not needed, seriously).
Other Party Effects: Off
(I find it hard to focus on what is going on with too many flashy things pouring all over my screen.)
Occlusion Culling: On
Shadow LOD: On
All other settings at max.
I like to play on Full-Screen.

Results:

With v-sync on, I maintain 60 FPS just about everywhere except for in Mor Dhona which can drop FPS to sub-30 numbers with everything maxed. A few tweaks on the settings can raise you up to 35-40.
I haven't taken a peak yet at my FPS in a 24-man raid, but there was no indication to me that my FPS was dropping below 30 with the crossfire cards.

With V-sync off, I get up to about 85 FPS in non-populated areas, so keep this in mind if you're trying to hit 120FPS on 4k (REALLY? Who's trying to do this right now?)

GPU RAM utilization hits about 2GB under 4k, so there's still plenty of breathing room if you're looking at using 3GB cards.

Did you find how to solve this issue ? I ditched the 4k enhancement proposed by nvidia on 1080 screens because of this.

SqEnix, could we at least get some sort of acknowledgement that a fix is on the way for this? I'd love to take advantage of my rig and 4K TV with this gorgeous game, but I need to be able to see the UI...
