First off, 30 hours is nothing in a Bethesda game and the problems will just continue to get worse. Second, the user having to find such workarounds (which will be rendered more and more useless as saved data files grow ever larger, anyway) is not a permanent solution. If you can live with paying full price for a broken product which is blatantly inferior to its contemporary console version in framerate, problem support, and visual quality despite its respective platform being every bit as capable as that other platform, fine... but that doesn't make it acceptable.
5 times happened in the most recent 20 hours I've played. If it should be getting worse the bigger the file gets, (it's currently over 9000!! kb), then in the next 20 hours I should be experiencing more than 5 framerate issues. We'll see eventually what happens.
Generally speaking, of course I agree with you. But for me, it's not a problem. (yet)
