Unofficial Skyrim Performance Boost

The Bethesda Softworks Forums have a thread on a new utility for The Elder Scrolls V: Skyrim claiming to offer framerate improvements of up to 40% on CPU-constrained systems (thanks Acleacius). Here's the skinny:
This patch will improve your frame rate by up to 40% in all CPU-dependent situations, i.e. especially in cities. It works mostly by rewriting some x87 FPU code and inlining a whole ton of useless getter functions along the critical paths because the developers at Bethesda, for some reason, compiled the game without using any of the optimization flags for release builds.

There has been some confusion about the original dll file and the current one for Script dragon. Script Dragon's dinput8.dll is 592kb The non working TESV Accelerator dinput.dll is 74kb

This "improvement" also causes most scripted events to not occur, so you shouldn't actually use it.

There was a typo in the DLL code. Specifically, the Test_Bit_30 function was returning bad results because the getter used was incorrect. The latest version has resolved this, so quests should not be breaking down anymore.
