Issues unresolved

Severe Hitching/Framerate Drops When Moving in Seamoth

Because of the way the game handles loading new objects, moving too fast through the world will lead to severe hitching and framerate drops, even on systems that far exceed the system requirements.^{[citation needed]}

Deleting the save cache and installing on an SSD can help, but this will remain a problem until the developer changes how they handle LOD scaling.^{[citation needed]}

Issues fixed

Game Launches in VR Mode When VR Isn't Turned On

Use -vrmode none parameter^{[citation needed]}
Launch the game with the `-vrmode none` parameter.

Game Crashes When Going To Specific Spot Or Hitches When Loading New Areas On Old Save

Fix save^{[citation needed]}
Go to the save game data location. Open the save slot folder (`Slot000#`). Delete `CellCache` and `CompiledOctreesCache`.
