Dual GPU support

[samfisher]

Using 13.10 with 2x 7950's and have no issues. Both GPUs spin up properly when game launches.

The latest Catalyst drivers 13.8 beta2 and 13.10 beta both have crossfire support for the game.

I have two 7850s and I don't really have any issues. Just a bit weird gpu usages, meaning the second card is showing 99% all the time, even when the game is minimized. I guess that's some sort of a bug. And the 1st card is used about 50% or something.

In crowded areas everybody is getting huge fps drops, no matter if it's a single 7850 or gtx 780 sli or whatever. I read someones post who mentioned that it's most likely due to current dx9 limitations which makes some of the "advanced" graphic effects heavily tax the cpu, at that point it doesn't really matter what gpu you have when you are bottlenecked by gpu->cpu->gpu or something. Hopefully we'll see better performance with the dx11 client.

I have 2x 7770ghz running and generally get 60fps (vsync is on) with the occasional dip to around 30 or so but haven't noticed any lower.
I made a custom profile for the game and have the crossfire mode set to AFR Friendly, the only issue I see so far is that the map will flicker

Seat the crossfire mode to Fear.exe for best results. No flickering of the map too.

If you have Firefox open, than that is the problem. It's a bug where the drivers continue using 100% to render Firefox tabs. Close it, or disable hardware acceleration in Firefox.

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.
