DirectX 12 was announced by Microsoft at GDC on March 20, 2014, and was officially launched alongside Windows 10 on July 29, 2015. The primary feature highlight for the new release of DirectX was the introduction of advanced low-level programming APIs for Direct3D 12 which can reduce driver overhead.
In Direct3D 11, the concept of feature levels has been further expanded to run on most downlevel hardware including Direct3D 9 cards with WDDM drivers.. There are seven feature levels provided by D3D_FEATURE_LEVEL structure; levels 9_1, 9_2 and 9_3 (collectively known as Direct3D 10 Level 9) re-encapsulate various features of popular Direct3D 9 cards conforming to Shader Model 2.0, while ...

Win64 is the version in the 64-bit platforms of the Windows architecture (as of 2021, x86-64 and AArch64). [b] [25] [26] Both 32-bit and 64-bit versions of an application can be compiled from one codebase, although some
On x86-64 and Itanium platforms there is just one possible hal.dll for each CPU architecture. On Windows 8 and later, the x86 version also only has one HAL. HAL is merged (or statically linked) into ntoskrnl.exe [2] starting with version 2004 of Windows 10, and the dll only serves as a stub for backwards compatibility.
The file format of a DLL is the same as for an executable (a.k.a. EXE), but different versions of Windows use different formats. 32-bit and 64-bit Windows versions use Portable Executable (PE), and 16-bit Windows versions use New Executable (NE).
Windows 10 Anniversary Update (version 1607) includes WDDM 2.1, which supports Shader Model 6.0 (mandatory for feature levels 12_0 and 12_1), [44] and DXGI 1.5 which supports HDR10 - a 10-bit high dynamic range, wide gamut format [45] defined by ITU-T Rec. 2100/Rec.2020 - and variable refresh rates.
Several macros affect the definitions made by windows.h and the files it includes. UNICODE – when defined, this causes the generic text datatype TCHAR to be a synonym of WCHAR instead of CHAR, and all type-generic API functions and messages that work with text will be defined to the -W versions instead of the -A versions.
