yah, i dont feel you will get many positive posts, other than mine. i dont have any game breaking bugs or glitches, yes there is the lag, sometimes. and everyonce in a while after it loads there is a low texture issue, but it goes away, and good to go. what would make a save file get so big? i am quite a bit over 150 some odd hours, and level 30, and i have about a 7.5 or 8 mb save file?
I think what makes the save file go up is affected by how much [censored] you've killed, how much you've explored and how many quests you've done. Also the amount of stuff you have in your house and inventory affects it a little too.
I haven't had many problems either, of course there has been a few freezes (I think four since the game came out). On my first character which I've played on for a little over 80 hours has an 11mb save file. There is some noticeable lag after an hour or two of playing when I'm walking around in Whiterun, and some random stutters here and there when I'm exploring. Nothing major. It didn't lag at all when (inb4civilwarspoiler)
Spoiler I was taking over Solitude after playing for nearly two hours
.
When I do play for around 4-5 hours in a row (something I rarely do) on my battlemage (about 20 hours in and a ~7k save file) I do notice the lag getting more annoying as I roam large cities.
As I've said before; I guess I was lucky.
