Hi Arma 3 Support folks. :)

I recently got Arma 3 and it runs at unbearable low fps even though I am way over the system requirements.
I assume the problem is somehow connected to some kind of incompatibilities?
Since any other recent games run as expected.

My CPU is a QuadCore AMD FX-4170, 4x3.6 GHz and my GPU is an AMD Radeon R9 270 (Curacao).

I've seen a lot of threads in different forums with possible fixes, none of which have worked for me, so I'd like to know if the reason for this behaviour is known and you can help me out with some definite measures.

Thanks in advance
Andy
