Dual GPU support

I was just wondering if dual GPU support had been enabled yet. I have 2 7970 toxic editions and I noticed that only one was being utilized in this game. Is this a plan for the future?

It already is supported. Are you playing in fullscreen?

Yes but when I was monitoring my gpu usage only one card was being utilized and I was dropping to 15-20 fps

Hmm, check with gpu-z to make sure it's enabled. I like to check in both the gpu control panel and gpu-z, to be sure. And remember crossfire/SLI is only active in fullscreen; fullscreen borderless doesn't count. Not sure other than that though, have you checked other games in fullscreen to make sure it's working?

Yea it works fine in Bioshock Infinite and Crysis 3 and in Borderlands 2. I will try the new beta drivers and see if that makes a difference when the game is back up

The 13.10 beta drivers were awful for me (like 15fps-awful lol), 7970 crossfire also. I'm using 13.4 right now and it's working fine.

I reverted the drivers back and I will see what happens when the game is back up.

The game definitely doesn't have proper multi-gpu support. I have two GTX 780s and whenever I enable it, some parts of a map work with it, and others it offsets the load so that both cards are sitting around 40-50%. Not only that, weird things such as choppy camera, slow/fast frame buffering, and other strange events occur.

The benchmark works wonderful with SLI but definitely not the real game itself. Disabling the second card runs it better for me. It's a shame.

Check out my guide on it if you want better performance out of them:

I have it working crossfire now but I get terrible results. Not sure why I get worse fps than when single gpu

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.
