Hi,RX Vega 56 user here. Make sure you have the latest AMD driver version installed. I'm running the optional version 19.9.2 and it works well with no issues. As for FPS, it always highly depends on your video resolution. My resolution can't go higher than 1920x1080 because my current monitor can't natively handle higher resolutions. I could use higher virtual resolution using virtual super resolution and GPU scaling, but the benefit isn't worth the loss of FPS in this particular game as it is a pretty demanding game. On my current resolution, normally I get around 60-80 FPS, sometimes above 100 FPS depending on location, but in some specific scenarios even low FPS around 30-40, again depending on location and complexity of environment. I would expect RX Vega 64 to give couple of more FPS and better experience overall, without BSOD problems.
