So i just checked the Tank DLC dev branch. Seems to be a little different but still the same issue.
So what is wrong with this issue report that nobody replies or assigns.
It has been about a half year without any significant change to this bug... and i know
i'm not the only one having it.

Congratulations!
Still not fixed in 1.84...

This problem is observed in many players (if not all) and it is very strange that there is so little attention to this problem.

Hello.

This is because of engine limitations. It could be fixed, but then your FPS would tank down and you wouldn't be able to play.

Before the patch with the new scheme for loading LODs, there was an acceptable FPS and correct loading of LODs in optics. After all, you can make a choice of options: the option before the patch and the option after the patch. It would be just fine, because in the current form, optics on islands with dense forests are useless, and the situation when people are visible without optics, but you cannot clarify their belonging to any fraction due to 2D sprites is simply absurd and irritating.

I'll just remind you what you have to deal with.

Please fix this problem, it became impossible to play
This problem is observed on all islands, not only from mods

I have this problem aswell. Its just frustrating to play PVP or TVT with this bug.

I'm excited with trees like these. Do not fix them! Give me my OFP back!

The same problem, need to be fixed. Just make stable render for optics.

#Bis when you it fix?

Still an issue as of July 2021

Wow, stuff is going on here! Still "Assigned To None" and after loads of great patches, the change ist "None" too.
Thx for pointing out to Wulf, that before the patch, stuff is running fine and LODs looking good and after, its running the same but if zoomed in... (QDesnik)
The fun thing to watch, when going into an optic, is: For the first quarter of a second, the LODs look fine, then they degrade. Mostly the bad LODs are in the centre
and if you move away they get better. Found myself trying to get a specific tree to LODup, to spot and then shoot where i saw the enemy. :P
I wouldn't be surprised if the bug is just a few numbers mixed up.

Divide these problems with trees per tree
Find model name and place here or create one ticket per tree

I think it's will bump and problem will be solve anyway

Well if it would be just about a few trees, i would say yes. But its about half the trees and bushes. Reeds and palm trees are the worst i guess.
When i find the time, i will try to find a different approach.
What gets me is: The bug just got his 4th candle on the cake... May 16th 2017 with 1.70 and Jets DLC.
If the fixing keeps the same paste, it will be my favorite ArmA 4 feature!

Still assigned to "None", still present in the same way in 2.10.
5 years anniversary of the post.

This still happens even in Reforger so don't get your hopes up =p

PS: It is even worst in Reforger btw

Well LOD's at distance are definitely less crisp than in ArmA at distance, but they are even in style.
When looking around with a binocular, they pop in quickly, but if you come back later it doesn't have to load anymore.
Well, still an alpha of an development stage game, which has a lot of promising features to it.

Shameless plug alert:
Reforger mouse
This is my biggest problem of Reforger for me. Since the best game is useless, when input is weird.
Reminds me of the classy framerate/mouse speed/fire rate dependency of older titles (Armed Assault / ArmA 2?)
That report seams to go nowhere, so if you have the same, or you don't, drop by and say hi! :P

Greetings from the land, where the FIA bought the surplus uniforms from!

This is just extremely disappointing.
Now we get "Extreme" graphic setting and still the refreshing and cool: Oh you are looking at that tree directly, let's reduce LOD to minimum.
This whole bugtracker thing is just garbage.
Jerking off the community for ideas and support and not giving a shit about supporting the community.

Should rename the site feedback library. Juuuust put it in the shelves.

I agree with you. They don't care about the players and their game. What are we paying for?
But we bought a reforger. But they don't care, they think what kind of beer to take to play war thunder...
