Starfield Stuttering Every Three Seconds in Interior Areas?

[Marksamusprime]

Was having this problem forever, both in Cydonia and Neon. Every 3 seconds no matter the graphic settings. It's a built in Vanilla problem. I solved it by installing Starfield Engine Fixes from here https://www.nexusmods.com/starfield/mods/10457. Then after the install I opened the installed "StarfieldEngineFixes.ini" file in Notepad and changed the line, "bEngineLoadOptimizer=0" to bEngineLoadOptimizer=1. That stopped the stuttering. (except for the Ryujin Operations room, that still stutters)
