Lately I asked myself which compilers are used by game developers for "resource-heavy" games like GTA or Fortnite.
I can hardly imagine that common compilers like GNU or Clang for C ++ can keep up.
As I said, I would be interested.
Clang is the best C ++ compiler in the world. GCC has caught up in the last few years and even the old MSVC ++ has gotten a lot better lately.
The ICC is a niche and mostly Clang ++, MSVC ++ and G ++ are used in that order.
The Microsoft Compilers (MSVC Build Tools) are often used especially for Windows platforms. Otherwise LLVM / Clang. Some companies probably also use modified compilers, but as far as I know that is less the case.
Difficult to say, especially since that changes all the time. But ICC should be the king. Also, G ++ probably still stands out from CLANG.
However, MSVC will still be used frequently under Windows.
