Game slowed to a crawl

Lagopus

My save game is now a slideshow of approximately one frame every 2 seconds.

I started playing SN in late July this year and have invested time in exploring and creating my bases over (steam reports) 302 hours in Survival mode with a single ongoing game save. Since installing the game I have upgraded my GFX from nVidia GTX1060 6GB to a RTX2060 6GB about 3 weeks ago. Then the little-big-update happened. Since then the pop-in distance became so close that I could sometimes be on top of scenery before it resolved to normal textures. I have always run the game at max settings as my rig has sufficient capability to do so. (i7-6700K, 32GB, Fast SSD, GFX as noted above)

Now, I have experienced occasions where the game would slow to a crawl. On those occasions , as I have been saving regularly, I could revert to a few minutes before and when re-starting from the saved position everything would be normal again. I have tried changing Graphics settings to Medium or Low in these situations, but that seems to make no difference and only a re-load of the save fixes it.

Now this time I accidentally hit Save instead of Quit on the Escape menu (due to having a momentary twitch in my hand whilst moving the mouse) and now when I load the saved game it is immediately in this slideshow situation and is totally unplayable.

Please help

I have uploaded dxdiag and output_log.txt to pastebin, however output_log.text was 36MB and I was unable to upload the whole thing so I have included the first section up to LOADING FINISHED. The next section goes up to the beginning of thousands of very similar entries like this:

Missing octree in LargeWorldStreamer.GetBlockType((-48.2, -19.0, -483.1)) for (block 1999,3021,1564, root 62,94,48, coords 15,13,28)
(Filename: C:/Subnautica/plastic_workspace_unity/artifacts/generated/common/runtime/DebugBindings.gen.cpp Line: 51)

The final section is from the end of those entries to the end of the file.

As I don't seem to be able to edit my initial post I shall add here that in the folder:

C:\Program Files (x86)\Steam\steamapps\common\Subnautica\SNAppData\SavedGames\slot0000

there is not a sub-folder called CompiledOctreesCache

Which might explain why there are so many thousands of the errors saying 'missing Octree'

Saves no longer include CompiledOctreesCache; that went away when terraforming was removed. The original CompiledOctrees Cache is located elsewhere in the game files; that is likely where the problem lies.

You could try verifying the game files on steam; maybe delete the CompiledOctreesCache from the game files first. (Not in save files. I don't have it installed right now, or I would find it)

I have already 'Verified' the game files through Steam. However, I will search for the CompiledOctreesCache and delete it then Verify again.

@narfblat That did it! 303 hours and continuing to count. Thank you for saving my game.
