> I did not say that everyone was using ICC, rather that desktop and game developers did not share the same opinion regarding ICC and Visual C++ Yes, sure. MSVC is garbage clearly isn't right. I presume (in the absence of any real data of course) that ICC doesn't result in significant performance advantages over MSVC, for games, or it would have been worth these developer's time to support it. > if you are reducing the world to just what Unreal, Source and CryEngine officially support It's a reduction sure enough, but I think that's a reasonable set of engines to consider. > I wonder how many AAA games have been released on Windows using GCC or clang with those engines I imagine it's none. According to the (quite possibly stale) official wiki, Source does not support Clang, and only supports GCC for building Linux dedicated servers. [0] It looks like Unreal Engine supports Clang for Linux builds [1], but for Windows it seems they really only support MSVC, although Clang can be made to work [2][3] CryEngine supports Clang for Linux builds [4], but not for Windows where it seems to be MSVC-only [5][6] [0] https://developer.valvesoftware.com/wiki/Compiler_Choices https://developer.valvesoftware.com/wiki/Compiler_Choices [1] https://wiki.unrealengine.com/Compiling_For_Linux https://wiki.unrealengine.com/Compiling_For_Linux [2] https://docs.unrealengine.com/en-US/Programming/Development/BuildingUnrealEngine/index.html https://docs.unrealengine.com/en-US/Programming/Development/...
