Modder squeezed out of the Skyrim additional 40% performance
In the forum thread, he says that, along the way, does not use an optimizing compiler.
Its optimizations are fairly simple and cover approximately 1% of the entire engine code. This is mainly manual inlaying getters, rewriting some pieces of code from x87 to SSE2. Only three major functions were patched. Modder claims that if Bethesda used an optimizing compiler and another library for mate. computing speed increase would be 100%.
