@Tenshi I would be glad to sit in a discord call with you and try to narrow down to issue, if thats a possibility. Though im pretty convinced it should be an easy thing to reproduce. I could be wrong

i can get a vid from every sideways/trick/combat pilot showcasing this issue. if that isnt enough i dont know what is

Also @Tenshi correct me if i'm wrong but you seem to be (zoomed in) in your screenshot. When zoom is toggled I believe LODs behave differently, appearing at a further distance. Most pilots dont play while fully zoomed in

You probably noticed but the two above links are from 2 separate users. The first link being all low graphic settings and the second link all very high graphic settings.

There are probably hundreds of unlisted clips that feature this issue. It is definitely a well known issue amongst arma 3 pilots

My apologies if the tree names listed above arent the correct ones. I ignorantly copy and pasted the names from a different ticket without knowing if it was indeed the trees in question. I didnt have the knowledge necessary to provide you the exact tree names.

This video was taken at X=071 Y=154 and features one of the popular dead trees with popping issues. The first clip shows normal flight through a common route in one of arma 3s most famous game modes, king of the hill.
the second clip shows the tree staying rendered for a longer distance after popping in. before disappearing again
the video was taken in the editor to show it isnt a server side issue. and I could gladly provide my config file with all video settings.

Sure. i will post a video shortly
