Limsa Lominsa video problems

I'm currently running a MSI GE70 with windows10 on a SSD. I have no problems playing this game at 60 fps and have been since 2.0 launch. I've noticed the last few weeks that my game was slowing down. I figure there was some serious issues so i ended up wiping everything and going with a clean install. It worked great after that then started running slow again. After alot of trial and error i narrowed it down to the GPU shutting down and it ONLY does this when in limsa and outlying zones (la noscea region). To get it back i have to bring up the Nvidia control panel and restore then set it to "Use high end graphics processor" as default. Otherwise the pc runs stupid slow and game plays 18-22 fps off the integrated graphics. Does anyone have any ideas? this sucks when I cant go to certain regions. I even changed my GC so i dont have to deal with it daily.
