Good job!

FPS = Frames Per Second
Means the fps the game is running. You need 30 or more, other wise you´ll see the game like slowly. (Try to uncap you frame rate because you probably capped it to 30.)
The normal FPS nowadays it´s 60-144
It worked for me, try to get again the item quest and do not activate it while selecting a NPC (Watch out, maybe you didn´t complete all the quests you need to activate it)
