Desktop and Game developers happen to share a different opinion.

  Does ICC have any traction in the gaming world?

    It does on Windows shops that care about the ultimate performance optimization on Intel CPUs and vtune integration.

      Doesn't that describe all high-budget games? Would the average Unreal-based game be built with ICC?

        Depends on the studio. Here is an overview and some testimonials, https://software.intel.com/en-us/gamedev/tools https://software.intel.com/en-us/gamedev/tools

        At a glance it seems the answer is No. Unreal Engine 4 doesn't officially support icc, for instance. Neither does the Source Engine. I believe the same goes for CryEngine.

        Going back to my initial reply, 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++. Specially given the lack of tooling that is only matched by C++ Builder, although I did not refer this point on my original reply. So if you are reducing the world to just what Unreal, Source and CryEngine officially support, I wonder how many AAA games have been released on Windows using GCC or clang with those engines.
