The games coming out now are truly pitiful, they really are. Mind you, some of the early DX11 stuff was just as bad in hindsight. I think about the best launch game for performance was Dirt 2. Everything else took way more power and didn't look all that clever.
What is funny though is you could hack Dirt 2 and enable all of the lighting and shadows, DX10 would take care of it. The only part you couldn't have was tessellation which tbh was pants in Dirt 2 any way.
I think people were expecting miracles of DX12, when in reality it's a bit crap really.
Gears of War 4 turned out all right—but definitely not great. Doom stands out as an accomplished title. Overwatch works well, too. The last great game, however, that comes to mind is The Witcher 3. That had a few problems like any release, but in all it was extremely well made. Another gorgeous looking game that runs well is Battlefront.
