My understanding is that 3D models rendering (from buildings to statics to AI aircraft) has impact on performance and FPS, not the groundnets size or their number of nodes.
That's good to know that it isn't the groundnets causing the difference in fps. When you refer to "AI Aircraft", are you talking about the aircraft traffic which move over a groundnet or those in AI scenarios?
There is a frequent message shown at startup that indicates something like "For better performance, try disabling AI Traffic." The check box is under
AI, Traffic and Scenario Settings, Enable AI Traffic. When comparing checked vs unchecked performance, I generally realize a difference of a few fps. But on a couple airports lately, I've noted a very significant difference, Could it be only the amount of traffic at that airport or scenarios associated with that airport rather than the groundnet causing fps drops? What I'm seeing is definitely related to the
Enable AI Traffic checkbox.
I can't remember at which airport I saw the greatest difference in fps, but I will try to find out and maybe we can compare results. Thanks for your reply!
