Had to force dx11 as dx12 was giving me around 15 fps (vs 35 from dx11).

Also, vulkan completely didn't work for me with the error of "LogWindows: Error: appError called: Assertion failed: bSuccess [File:C:\BuildAgent\work\9fc8da665efb5ffd\UE4\Engine\Source\Runtime\VulkanRHI\Private\VulkanCommandBuffer.cpp] [Line: 503] "
