So ever since the launch of the game, the mesh streaming has not worked correctly.
I made a post shortly after launch but the issues persist.
Link to the old post:
I don’t know what causes it but no patch has ever fixed it, only a workaround was found by going into the game files and manually disabling mesh streaming, but this has a profound effect on performance.
I added (today, meaning it will come in a future patch) so you can override the mesh streamer to disable it from user settings (currently you can only do it by modifying the steam/msstore data in settings*.ini files).
We will take a larger peek at this system in the near future to mitigate some of the issues.
Much appreciated, good to know you are aware of the issue and are taking measures to fix it.
The in-game setting for the mesh streamer will be a good addition until the issue has been fully resolved, looking forward to trying it out when it is added.
