Graphical glitches in Doom after upgrading to Vega 56

So I just upgraded from a GTX 970 to a Vega 56 (a snip at £230!).

I removed the 970, installed the V56, uninstalled nVidia software/drivers, installed AMD drivers, now I'm getting this strange artifacting in Doom when using the Vulkan API (fine in OpenGL). Seems to only happen with things with a blue glow effect. Other than that it's running fine. Specs are:

  • Intel 2600k i7 CPU
  • Asus Maximus Gene V mATX motherboard
  • 16GB of RAM
  • Windows 10
  • 650W Corsair PSU
  • Powercolor Red Dragon Vega 56 GPU (with latest drivers I assume given they're downloaded)

I've tried running DDU in safe mode to get rid of both AMD and NVidia drivers, followed by an install of the latest AMD drivers...still does it. Anyone have any suggestions? Thanks, Tom.
