Crytek and Warhorse worked together to get the engine to DX12 and improve multithreading so much.I'm not sure if it was Crytek with Hunt game of Warhorse itself - someone fixed the engine and KCD2
KCD1 nextgen patch was done by Saber with support from Warhorse.
Those bugfixes are now in PC version as well, it is patch 1.9.7this patch on console also introduces a bunch of bug fixes that never got addressed in the PC version.
