Do you have the same issue if you follow the OP’s steps to reproduce it?
Yes
Provide extra information to complete the original description of the issue:
FPS is starting to drop during landing at 100-200ft above ground. On ground FPS is terrible. After takeoff at 100-200ft above ground FPS is better. Above 200ft from ground there is no FPS issues. I tested this issue also on smaller airport CED3 and results are similar.
