AMD's driver for 7870 did not package the Vulkan run time libraries. Other AMD drivers (e.g. 380) work fine.
Was attempting to repro [Link Removed] in //UE4/Main when I hit the following crash
Result: New standalone process crashes on splash screen
Expected: Option is greyed out or prompts user with setup instructions if they don't have the SDK installed
MachineId:664A3B6E473BADAB41AE90B4A8B67613

Assertion failed: 0 [Link Removed] [Line: 488] 
Cannot find a compatible Vulkan installable client driver (ICD).
Please look at the Getting Started guide for additional information.
