Crossfire Load horrible on DA:I

[Reidlos65]

Some games recently have run horrible with crossfire and DA:I for some but not all apparently is one of them.

When I use my 7970 GHz in crossfire, I get half the Frame rate in Dragon age Inq.

I use GPU Z to observe the load and I am running 1 card at 70% and the other 0 to 20%.

Is there a way I can fix this or is it just hope patchs and drivers update?

Using Mantle? Try DX11 instead.

Reviewers are seeing 100%+ scaling @2560x1600 in this game with a 7990 (same as 7970 crossfire), so I'd say something is definitely wrong with your system.

1) Are you using Mantle or DX11? Try using the opposite of whatever you are currently using so we can rule out the APIs.

2) Have you upgraded to the 14.11.2 betas? If not, do so: http://support.amd.com/en-us/kb-articles/Pages/AMDCatalyst14-11-2-BetaWINReleaseNotes.aspx. The beta drivers have an optimized CrossFire profile for DA:I.

Let us know the results.

there are plenty of review benchmarks out there showing how great crossfire is scaling in arma3, but i can tell you from experience, it just doesn't work, i have many hours into the game and i went through probably 10 amd driver releases/system reinstalls/ and even giving win8 a test, even tho ill never use it... there was a very short period where i got the crossfire to scale over 90%, and it was some kind of a fluke, because most of the time using crossfire in this game is the same or worse as using a single card,
and the community arma3 benchmarks prove it,
i've seen a bunch of people who use crossfire having the same issue,
crossfire utilization 20-50% most of the time.

I've a 7950 crossfire setup and both of GPUs seem to be working at almost the same level in-game (DA:I).
Like others have said, do not use Mantle, use DX11. Mantle did not work for me either.

Try reinstalling your drivers. Use DDU to remove the old AMD drivers and allow it to go into safe mode. Then reinstall the newest drivers and hopefully this will fix your problems.
