Compiler and CRT
VS 2019 Update 3 includes a new version of the C/C++ compiler (19.23.28105.4).
The C/C++ Runtime (14.23.27820) is included in this update. Remember that VS 2015, VS 2017, and VS 2019 share the same runtime redistributable binaries and are ‘binary compatible’.
/std:c++latest switch enables support for C++20 draft features including C++ Concepts.
DirectXMath: There is a known issue where the
IsNan tests can fail when building with
/fp:fast due to new optimizations. This is fixed when using DirectXMath 3.14 in combination with this update.
