Never said it was, the multiple render paths may of contributed to the lack of testing it seemed to recieve to fix the bugs. In truth most PC games are no longer worth pre ordering till you know where the game stands compared to the console version. Closer you are to a games minimum specs the more true that stands. There is only Doom on PC that has not suffered some launch issues of the big AAA games released in the last year. Vulkan seems to offer higher max fps vs dx12 but with lower min fps. I'd prefer a more stable min and max which dx12 seems to offer more in the games it's in. I wonder if Vulkan is favoured more by some cause it does not need Windows 10.
