Forcing multisample in AA transparency on Nvidia causes trolls to be see through. fix please.
You need to look at http://www.geforce.com/Optimize/Guides/the-elder-scrolls-v-skyrim-tweak-guide/#19, most notably this quote:
Multisampling TRAA should not be used in Skyrim, because this causes a glitch whereby some portions of solid objects, such as other characters or creatures, become see-through. The main options are various levels of Supersampling TRAA.
You likely have transparency AND multi-sampling AA enabled in your Nvidia drivers and that is a configuration that is not supported.
