video lag, I'm about 40 hours in, save file is about 7.5mb. I've gotten a couple lock ups( for those only couple hours of play time though)
I've even went as far as 12 hours with no lock ups
finished over 30 quest and still have like 30 open
starting the thief line in riften I got huge amount of video lag, for me to get through it, I just kept going in circles like buffering the world till the fps picked back up till I could move around in that area. ( best I can explain it)
