I had Ebony Armor before and I had the occasional lag and hiccup in Skyrim, but when I got Stahlrim armor and greatsword, the lag is a lot more noticeable in Skyrim. I'm also having more freezes, like 1-2 every day, sometimes not at all. I'm on PS3. Also could it be that I have a 9.8 MB save file? It's after 1.8 patch, I made this character.

There's no reason that it should, but then again you're playing on PS3 . The game runs fine for me with all DLCs at a 14 MB save file on PC

Not for me.

It's the amount of stuff that has been added now that we actually have all 3 DLC's.

There's not a single armor texture in the game that should cause lag. A 10 mb save is not that big...well, pending the hrs of gameplay.

I have 35 hours of gameplay, but I rushed through all the main quests(DLC and main game) and the thieves and a few other quests
