The beta branch seems to not have fixed pathing in the dungeons of Tradu mines among probably other things. For example, the walls of certain areas of the Crypt appear to be missing compared to the normal build. Or the path in Skywalk on the left tunnels become unpathable halfway through. I believe others have reported similar issues on the beta branch and this might also be affecting other lower level dungeons from what I’ve heard.
Other than that the performance is much better overall regardless of the pop ins.
