Skyrim was coded in x87 code. It does not have SSE optimization which has been standard for both AMD and Intel for nearly a decade now. Never-mind the new advanced vector extensions now available. They should have optimized for SSE 4 and AVX... not x87. This is just a total blunder on Bethesda's part and absolute embarrassment. Unbelievable, I just can't believe they did this. Confounds me. This is probably among the top reasons why Skyrim only runs on two threads. http://en.wikipedia.org/wiki/X87 What a f*cking joke. Last time anyone cared about x87 was when the i486 was still being used.
