So I get playing and this game is as smooth as anything for nearly 40 hours. Now I've hit 43 hours and my savefile is 11mb. After an hour my game stutters every few seconds, I'm lagging in whiterun. Objects are now popping in really close like a bit of mountain popped in like 20 metres away. Apparently a developer said they had mastered the PS3 in a magazine, I dont think so it's exactly like fallout 3.
