So I tried the temporary solution.Clean cache, delete install Skyrim, dawnguard and dragonborn. Delete non-important saves.Delete patch Re-install. At first it looked really good. No freeze on my first draugr encounter. But in the next room (the one round room with several draugr deathlords) it froze again.
Restarted and used an earlier save and didn't bother with Raven Rock mine anymore.
Outside it worked like a charm, talking to people, buying stuff, no problem.Untill I approached some "ash people" and started getting at it. It froze again.
So now it is unplayable for me. Once the action starts (when 3 or more ennemies get at it) it freezes. Performance problem?
If this does not get fixed then I want my money back. I did not pay for dlc that freezes everytime the action begins.
I haven't tested it in Skyrim yet, but it doesn't look good.
So no the "temporary" solution did not work for me.
I also disabled all autosaves, so I think it does not have anything to do with saving the game. At least the freezes I get, they happen in game, anywhere once a lot of stuff is happening at once. A performance problem.
The ennemies are harder to beat, the fights take longer and adding potions/shouts seems to make the freezing worse.
If you see no ennemies everything's fine, the moment I see multiple ennemies that's when it starts, even walking away from the action will result in a freeze.
2 days ago it froze about 30 times, I was really determined, but gave up eventually.
Yesterday I restarted the box 3 times and that was it.
To me it is UNPLAYABLE!!!, unless all I do is talk to NPC's, buy and sell stuff and NOT act like a dragonborn!
