Those are the screenshots you provide and yet Ubisoft gets ****ing hell for downgraded graphics, but those blurry diarrhea stained "art style" graphics and disastrous game optimization gets Blizzard a free pass on the fanboi bus. How can a game that ugly be that CPU taxing honestly. I get that it was call "stylistic" when it launched it was low poly and low fidelity for a reason, but today come on really Mona Lisa I'm not buying it. Those WoW textures are downright gaudy as hell mixed w/over saturation.
You miss the point it's a carrot on the stick game millions of idiots will buy it thinking DX12 improved the game graphically and for the majority since they are Nvidia users won't see any improvement at all! As a nice bonus though the DX12 will make it more accessible to the AMD users in case they couldn't run a decade old game that looks like "stylistic" rubbish!
