Speaking of which; there is one part of the AI system that causes some (currently unavoidable) stutter. Models are loaded on demand, and this causes some stutter. Mathias has indicated trying to move the loading process out of the main render thread, or something like that. I'm not sure how much that relates to the issues Tim mentioned in this thread. In addition, there are a few other candidates for causing stutter in the AI system, in particular the route finding algorithm and the traffic separation detection code, because these are requiring peaks in CPU activity. In particular when two aircraft request these functions in succession, there can be peaks of activity. However, having said that, these AI related issues are quite unlikely to cause the observed stutter, for two reasons 1). Heiko's original report in this thread explicitly mentions that he has turned off traffic manager and AI, and 2) I'm also seeing these stutters occur even before the AI traffic system starts loading.
