I also have the FPS drop issue. I have noticed that the models don't have LOD. On an airport of this size I think having LOD modeling may help to improve fps. Will this be implemented in the next patch? Thanks.
Support overload. We are currently seeing 65% more demand for support then we normally see. We can only assume this is because more people are at home due to the corona crises. Our complete support staff is online and they are working flat out, but it will take some days before we can scale up resources. Please be patient.
