We've received a couple of emails from pilots about the increased choppiness of Infinite Flight since updating to 1.5.
Rest assured that we're working on it, the issue might have been located already, and once we're sure of what the problem is, we will publish an update as soon as possible.
The problem seems to be in the code that creates the ground tiles, so flying at lower speeds helps keep the stutters to a minimum.
We sincerely apologize for the inconvenience and thank the pilots that reached out to us about the issue :)
Happy Landings!
