What i do is not hold to many quest and to do them as soon as i get them. I hear that people lag like no lag has lagged before, not an issue if you clear things with NPCs. I remember when i had that Dog quest (deadric quest one, Falkreath) and the game lagged so much but thats because the dog was with me. I did do the main story quest and they say after that the game lags, it did but didnt after i did some quest and or started somethings like ( joining legion or Stormcloaks) Miscellionus quest. Thank you for listening guys, Love Bethesda, Love Skyrim, Love Todd LMAO!
