Lastest AMD drivers

2 x 7970 GHz editions

high to med settings

 

 

HALF the frame rate of one card.  Using GPU Z I see my main card 70% utilization and my second card using 0 to 20%

How is this happening to so few people

By latest, do you mean the 14.11 beta drivers?

And why aren't you using Mantle?

the 14.11.2 and im not using mantle because it takes 2-3 mins to load my game and causes a not respond issue that goes away but essentialy freezes the software for that whole time

I found performance with DX terrible (R295x2). I struggled to get 30 fps. But Mantle and 14.11 solved all my problems (though it slowed loading to a crawl - and installing 14.11 took several tries).

I can't use Mantle either or I get freezing every 20-30 seconds for about 5 seconds.  This is with 14.11.2 and Crossfire on.  If I turn off Crossfire I can use Mantle and not have any issues.  If I run DX11 with Crossfire I get no problems at all.  Solid 60 FPS with all settings on max but MSAA on x2 at 1440p.

 

The beta drivers would not install right either without me doing a Uninstall all AMD apps, then running AMDs driver cleaner app, then installing the 14.11.2 beta.  After I did that Mantle was able to be turned on , but it still sucks compared to DX11 at this stage, its early though so maybe it will get more optimization.
