Compared to the old catalyst drivers, the new driver crimson edition on the example of battlefield 4 show 10-15 fps less than the catalyst drivers. What could be the reason ?
It's difficult to say as you have not provided much information.
AMD Graphics Card
Can you benchmark the difference between the driver versions please so we can see what the difference is?
Crimson 16.4.2 is available for download here.
Unfortunately Mantle will not be seeing any further development, so if performance has dropped i would recommend to use an older drive.
