Its not that it would be a bottleneck on horsepower alone. Some Developers just neglect to optimize their stuff on Amd platforms, especially early access titles. For the most part any Fx processor above the 8320 can handle a Gtx 1060. I upgraded my Cpu to intel for Arma 3, Squad, H1Z1 and Dayz among a couple of others (Htc Vive games).
