Most of the CPU time spent by game is not spent in the main binary file, but in system libraries: 3D graphics (via DIrect3D, OpenGL, or Vulkan), physics simulation library, etc. According to the article, Fex would emulate the amd64 instruction set for a while, but also translate the library calls, which allows the use of native Arm libraries, with only a thin translation layer in between, not really different from what you need to call c library from a python code.
