@Geez Thank you for the answer and the explanation, but unfortunately it does not satisfy me. It's 2023 not 2000. With the new engine we need something better that this.

In Arma 3 in RHS mods I can set the scopes display in three ways. 2D, 3D and picture in picture.
The one that resembles the Reforger scopes is PiP.
So why not make a LoD setting for PiP?

It looks it's server dependant. On some servers it works like in the video, on other there's no difference in detail level between 2D and regular scopes.

I've made a ticket on the same problem. It's "Awaiting internal Testing".
I think it would be good if you attached console.log
Just enter some modded server, play for a very short time, leave the server.
Join other sever where you cannot move, exit to the desktop.
Then copy and paste console. log here.

I know it sound obvious, but if you're using OEM automatic updating software for your system components, some things may not be updated. Update everything manually. Try clean install of GPU drivers. Use Display Driver Uninstaller. Update your BIOS.
At the moment Reforger do like to be on the same disk as an operating system. That includes MyGames folder. Try changing that.

Ok. I hope BI will finally fix it. It's really annoying.

I could not recreate my problem so far. It was tagged as "Resolve".
But yours and my problem are the same.
I've found such information (https://earlygame.com/apex-legends/how-to-fix-engine-error-0x887a0006):
What Causes The Engine Error 0x887a0006?

BTW, could you add a fragment of console.log before the crash?
That's where I get more accurate error description.

Yep, I was a bit confused and annoyed with the inability to log in with my BI account. Probably preventive complexity.
As I said, sometimes it's worth checking all the updates.
I also regularly (once/day) use some system cleaning app.
Let's hope that all this feedback stuff will bring some positive outcome and Arma 4 would be less buggy then it's predecessors.

Mate, I know it may sound obvious, but try updating everything in your computer. I mean like BIOS firmware, motherboard components drivers etc. In the ticket I created I had/have a problem with DXGI_ERROR_DEVICE_HUNG. As I've written, since yesterday I cannot recreate it. But after that I updated BIOS manually (automatic update didn't show that there's a newer version), therefore I thought everything is up to date.

As for now, after +/- 2 hours of a gameplay on a various modded Conflict servers I could not recreate the issue.
