Both AMD System Monitor and MSI Afterburner show, that one of the GPUs is not being used at all, even when 1st GPU is at 100%. This happens on Catalyst 15.7.1 and the newest beta 15.11. I tested 3 games: Fallout 4, Guild Wars 2 and League of Legends. In none of those was the second GPU used. After uninstalling new drivers and changing them to the oldest I could find (Catalyst 12.1) second GPU was finally being used, but only in LoL where both 1st and 2nd GPUs had the same numbers. In GW2 second GPU rarely used 5% of its power while GPU1 was at 90-100%, same in Fallout 4, please help.

My specs are:

WIndows 7 Ultimate x64

Intel Core i7 CPU 950 @ 3.07 GHz


If any further information about my system is needed I will provide it as soon as possible.
