See attached picture. I couldn't identify yet a pattern when this occurs. Does anyone have the same issue? Skydemon version: 3.16.13.383 Running on an iPad 4 mini with iOS 15.8.2.

Yes, sometimes a bit more, never more than, I would say, 5 sec. (which is relatively a lot when you're trying to stay out of a class A in a dense environment). I don't think it's related to the GPS chip, maybe something to have with compute power?

Does that mean that with a more powerfull iPad (performance wise), this would relatively be shorter or even almost disappear?

Group: Forum Members Posts: 8K, Visits: 8.9K	No, SkyDemon purposefully only recomputes virtual radar every five seconds by design, no matter how powerful your device is. We could change that of course, but it doesn't seem to have been an issue. If it's an issue for you, please describe in detail the situation where the lack of instantly-updated data is a problem for you.

If the trade-off is a less accurate radar view, then clearly it's not worth it. Now that I know why it's happening, I can work with that. It just caught me off guard the other day when I was navigating through a complexe airspace (in some situations, if you're not expecting it, it can throw you off kilter).
