i7 6700k @ 4.6ghz
Win 10 x64
Sapphire R9 Fury X Crossfire dual gpus
for the most part crossfire does perform well and i get solid 100% gpu usage and high frame rates. But it is also common that while playing there will GPU usage dips where it goes from 100% down to 30% - 0% and it causes the frame rate to take a big dive for a second or two.
Power Efficency has been set to off.
I am using the latest drivers, I have tried re-installing with DDU and clean express option.
Does anyone else experience the same symptoms when using crossfire?
