    RX 480 CrossFireX issues (all games)


      Hi all.


      I recently bought two Sapphire Nitro+ RX 480 cards to run in CrossFireX but this system doesn't work in any of my PC games (e.g. The Witcher 3 GOTY edition, Dark Souls 3 and so on).

      Each time I run them I "always" get 20-30 Fps but both cards run fine and load 90-100% (GPU1 and GPU2); the CPU load is from 80 to 92.


      On the other hand, when I run Heaven Benchmark all it works fine (I get 85 Fps on average, CPU load from 90 to 95 and a score of around 2200).



      What's wrong with my system? Do you have any suggestions? Thanks a lot anyway!



      My system information are:
