So, Skyrim's been under the knife five times already, and the sixth' time is quickly approaching...

Everytime I've read their patch-notes, introducing all the different repairings for the game, they always start of with the " General stability and memory optimizations " magic sentence!!

But what is meant, with "General stability" and "Memory optimizations"?
Is it the framerate issues and the lag..?
I'm just a bit confused I guess!

Please shed some light you guys!
