There’s quite a bit of performance issues in the beta due to the amount of objects that had to be rendered in the forest. It was actually quite a simple fix, just added occlusion culling to the camera and now framerates are considerably better throughout the scene. There are still a few hotspots, especially as you get higher up on the map. We believe that adding a level of detail (LOD) to the trees would provide optimization in these cases. We are working on getting that implemented.
Also in case anyone is interested we are doing a twitch stream tonight from 8-9pm (eastern standard time) showing the new beta content in action with commentary from the developers!
