Problem

During the development of our new project "Colossus," we encountered a significant performance issue. As our map expanded and more assets and foliage were added, our Frames per second (FPS) started to drop drastically. The FPS fluctuated between 10 and 50 every tick, hindering our progress. (You can view your FPS by pressing Ctrl+Shift+H).

Solution

We resolved this issue by deactivating the UDP Messaging Plugin.
