C++ code compilation time:

  • Linker improvements speeding up iteration build times with debug info by 3x (or more) on large projects. (Unreal Engine shipping configuration)
  • Link times also improved under /INCREMENTAL by 2x.

C++ code optimization:
VS2019 does advanced vector optimizations for AVX/AVX2 instruction sets, Xbox ATG (Advanced Technology Group) provided a benchmark based on code from Unreal Engine 4 for commonly used mathematical operations, such as SIMD expressions, vector/matrix transformations and sin/cos/sqrt functions:
VS 16.0 improves frame time up to 2.8% over VS 15.9(2017), and VS 16.2 got an improvement of 2–3% over VS 16.0.
