Catalyst 13.12 and Crossfire not working

Battlefield 4 General Discussion
1

I’ve got two 6970’s in Crossfire, and they don’t work together in BF4. I get FPS of ~40-50 on high when running the 13.12 drivers

When I back down to 13.9 I get 60+ FPS. But then I get the “battlefield is not responding” crash to desktop pretty frequently.

Any thoughts?

edit: found some 13.10 drivers, got my FPS’s back.

Stay away from 13.12! They are the most instable and they nearly killed my 280X!

My stability, temps etc. were just fine. Just that crossfire wasn’t working…

I have a 5970 which is dual GPU, and 13.12 makes my second gpu show as disabled adapter, and in GPU Z crossfire shows as disabled. Also in game second GPU has no activity. Changed drivers down to 13.9 and crossfire is back.

The 14.x drivers are working well for me now.

I actually tried the latest 14.2 beta drivers and same issue, second GPU says disabled adapter and no crossfire.

Wow. What was happening to me was that Crossfire was enabled still, and GPUZ showed it running just fine too. Just that in BF4, performance was that of having no Crossfire enabled at all.
