Tried installing Vivid Clouds and Fogs, as per step: core requirements, and per recommendations on your page. Opened Skyrim (via skse, of course) to ensure my game was still stable. Game wouldn't even get to the start option before CTD. -EDIT- for those wondering, I know it was Vivid Clouds and Fogs, as I had previously tested stability and that was the only mod I installed between. Used LOOT as per guidelines.
