When we add guard spawners to our project, it leads to noticeable stutters when we start the game.
We attempted to address this issue by disabling the “can ever affect navigation” option for static meshes, especially those animated with cinematics. We also experimented with setting all meshes to movable, but unfortunately, the stutters persisted. The only effective solution we found was to remove the guard spawner entirely. Which is not an option, because guards play a vital part of in our game.
