Hello everyone. Presently I am trying out a crossfire configuration with two HD6800. Aside from the occasional issues where FPS plummet to 15, I can play with around 40 or more fps most of the time.

This forces me to play in fullscreen mode however, which I have never done with FFXIV before because I did not like how the game looked at that screen mode. I do not understand why, but the edges of the windows are glitchy and the font simply looks weird.
This fullscreen issue does appear whether or not I have crossfire enabled. The second card has arrived a week ago, and I have been playing ever since the beta with these issues when I turn on Fullscreen, so it is not a crossfire bug.

PC:
Asus p5K E
Q6600 @ 3.2mhz
Kingston Hyper X @ 1066mhz
MSI HD 6850 OC Cyclone edition
XFX HD 6870
2 x SATA HDD Raid 0
Windows 7 64bit Pro
2 Asus VW222 - Changing the screen changed nothing.

Fresh Windows installation, reinstalling the game, changing card drivers, changing where the game is installed, etc, have not fixed the issue.

Curious thing: Screenshots do not show the issue. It all appears quite nice, however on the game client, set to fullscreen the font is messed, and the windows edges are glitchy.
