Nope, it's not the firefox, eventhough I do use it. But I have disabled hw acceleration anyway, it was giving me crashes in the game. Also having Firefox (youtube-flashplayer) open or not doesn't have any impact on anything for me.

I noticed that my second gpu would show 99% utilization whenever I launch GPU-shark or Asus GPU-tweak. But with MSI Afterburner this doesn't happen so I now use it for monitoring (with the on screen monitor).

So before I launch FFXIV the 2nd GPU shows 0% usage (it's in lowpower sleeping mode). After I launch FFXIV the 2nd gpu usage goes to 64% for few seconds and then to 99% where it stays. This also happens if I alt tab, it's 64% for few seconds and then jumps to 99% (no impact on fps). It's also 99% even when I have FFXIV minimized, I have enabled limit fps when client is inactive, but well this isn't really an serious issue though.

The gpu 1 usage varies from 20% to ~65%, highest I've ever seen with v-sync on. Without the frame limit it can go up to 97% provided that the scene is very plain and not npcs around. The crossfire definitely works, in the character selection screen I get around ~110fps without xfire and with ~210fps. Also when I'm panning around in a city with crossfire I don't really get any fps drops provided there's not too many ppl around, when in the same situation it drops to 45fps on a single gpu. However after the number of ppl is higher than a certain amount you are mostly bottlenecked by the cpu... I was getting 37fps in a very crowded hub and lowering the graphics settings to lowest for a test did improve the fps to ~60 but that was basically everything disabled.

I just use the 13.10 "default" profile.
