This has been a bug since the earliest Alphas of MSFS but it’s still an issue and it’s ridiculous that it still hasn’t been patched. I would argue that many trees are 10x the size they should be and honestly it looks like cities have been overrun by flora. The attached screenshots are from YLIL which is where I fly IRL. There are matching screenshots of a video taken IRL which I have replicated to show the issue. The trees in the sim are many times larger than they actually are IRL.
If for some reason this bug can’t be fixed by having trees a realistic size there should at least be a slider or something in the graphics options to scale the trees to a user adjustable size.
It breaks immersion completely because trying to judge height is impossible (I think oh I’m pretty low I’m only ~ 10x the tree height when in actual fact the trees are 5x their actual size so I am 5x higher than I expect!!!) and often trees are in the way of the approach or departure end of runways.
Even in the landing challenges that come by default in the sim I have been on a 3 degree glideslope and had to fly straight through trees to get to the runway!
