Funny thing I noticed. After increasing it to 20000 it doesn't really add 20 seconds to load time. It is far less if anything (all loading screens take no more than 3 seconds at most). Maybe it doesn't function properly...
I suppose it should add some time in milliseconds to the total load time but it doesn't seem to work. Maybe in Skyrim VR there should be some other tweaks. Wil try to investigate
Also what i noticed is that these freezes happen most of the times on the SECOND cell load.
For example,
I load the game, enter Riften. Everything seems kinda OK, then I try to enter the tavern → Hard freeze
I load the game, enter Riften. Everything's OK, I save the game, enter tavern → Hard freeze.
I load the game (savefile after entering Riften). I enter the tavern,everything's OK, I save the game, then I leave the tavern → Hard freeze.
I load the game (savefile in the tavern). I leave the tavern, everything's OK, I save the game, then I enter a jail → Hard freeze.
Honestly I don't really mind to loading screens to take even 30-60 seconds xD. It takes me 1-2 minutes to reload the game in VR in any case
Upd.: even fPostLoadUpdateTimeMS=100000.0 doesnt help. And the load times are as fast as always. Even the initial one was 9 seconds (instead of something like 109 seconds), I'm still wondering why
