The game (playtest version) runs out of the box. Performance is not great and FPS are fluctuating widely, but it is definitely playable. It seems to run a bit better if you switch to DX12 in the options menu. Also, the two options "Object Distance" and "Post Processing" have a major performance impact, so lower these first if you need more FPS. Since this is a UE4 game, I tried forcing Vulkan by adding the "-vulkan" command line option. This did not work unfortunately and only resulted in an error message saying that it was missing shaders which I guess would have to be supplied by the developer.
