Map objects flicker, houses and ships popup

[z-mann]

Since the update I have noticed flickering on the Syria and Persian Gulf maps - with different aircraft. Houses and objects, as well as ships (depending on what the map has to offer) appear quite randomly here. I have included a track from Persian Gulf.

Error PersianGulf.trk

Thank you for your answer. I tested it with your settings but unfortunately it doesn't change. Random map objects like houses, skyscrapers or ships still appear in the most unlikely places.

are you running mods?

Please attach your dcs.log file (from Saved Games/DCS.../Logs).

Yes, but no mods were required or active in the test missions

[Flappie]

You have a lot of mods installed. Try renaming your "DCS.openbeta" to "DCS.openbeta.bak", then run DCS and stt if you keep reproducing this strange issue.

Thank you for your quick replies. I had to do something in between, hence the delayed response.
I renamed the DCS.openbeta but the error still exists. I even saw him appear in the mission editor. So various objects appear again and again in the same spots

[Flappie]

That's wild. I've never seen this before.

1. Try a DCS cleanup and repair.
2. If that doesn't help, create a support ticket: log into DCS website, click "Support", then click "Create a new ticket".

Hello,

Same bug here since 2.9 update and still visible with second patch

Boats ( without texture ) pop -up and disappear randomly ( 2D, VR, MT, ST ) from cockpit or external view
ONLY when on airports ( caucasus map, persian map ... )

Here are some screenshot of the problem
And a mission to start in order to reproduce from cockpit view ( we hope it will be reproduced ! )

DCS 2.9 is stock and just patched : slow clean repair done, "saved game" renamed, etc...

I can see some error in log , maybe linked ?

Thanks @fab.13.

I ran your mission and took off, but I didnt't see any ships. They are LODs by the way (low polygons models that are supposed to be seen from afar). I compared your log with mine, then with @z-mann's. Nothing caught my eye.

Is Persian Gulf the only affected terrain for you two, or is this a coincidence?

[fab.13]

From few tests i could have made

The visual bug is visible near every airport on the two map i have tested :  i have been testing Caucasus and Persian map for now
The visual bug does not occurs when flying away from airport

I started to donwload DCS 2.9 from scratch on my previous machine in order to compare with my current game machine.

I noticed ships "growing" in one video showing OB 2.9 and it was quite distractive - that was the Marianas. Later I saw it myself in Free Flight mission for Yak-52 near Haifa - that is Syria map. Ships appear, then they grow as you close in - but not realistically, they really inflate - and then they shrink as you fly away.

My DCS was repaired after OB 2.9 update.

My LOD is set to 1, I can try again without DLSS whether that is an issue, although I doubt it.

[Flappie]

Please attach your options.lua (from "Saved Games/DCS../Config"). Maybe it is caused by some setting.

Given which ships (and other objects, but ships are most noticeable since they sit against a clean and clear background), this is probably a combination of the new LoD threshold setting and decoration rendering rages. It's as if the game determines that, oh, there needs to be decorative civilian traffic here, and oh, you're well within spawn range, and oh, it needs to scale up the LoD rapidly to match your actual range.

In the past, this was handled by fading stuff in, which also looked a bit silly but you didn't notice it as much as the visual of a ship suddenly coming at you as if it was warping in from Elite Dangerous.

The tricky bit about replicating this, and especially catching it on a track, is that these are largely randomised — it's the game determining that it needs to paint the world a little, and there's no telling whether it will do that on playback or even on running it live again.

Thank you, @virgo47. Unfortunately, I still can't reproduce the issue.

[fab.13]

The bug is not present on a fresh install on my older machine,
so not easy to reproduce as you say

The bug is present ( slow repair +  newly "saved game" ) of my current game machine ( options.lua is stock )
Easy to reproduce on my side : just start from any airport ( see screenshots )

If a reduce the LOD Factor to 0.1 ,
the objects pop-up appears very far but are still present on horizon ( horizon is flickering with pop-up )

LOD setting and algorithm seem to be related as said in previous post

The bug is systematic , i could stream a video through discord if needed...

No need for a video, I can clearly see the problem in your screenshots. But I need to reproduce the issue myself in order to report it.

Since you repaired DCS and renamed your "Saved Games/DCS..." folder already, I think you should take a look at your GPU. I see both @z-mann and @fab.13 have a very old versions of the NVIDIA driver (respectively 426.50 and 390.65).

@fab.13, we have the same GPU. Please uninstall your current GPU driver, install a fresh one (I use 531.41), and see if the issue persists.

[fab.13]

Bingo !

I installed 457.30 ( already on my disk ) and no more Bug
Sorry for the time spent about such thing

Bye Bye Nvidia 3 series drivers ,
Welcome 4 ou 5 series and new settings !

Some people tested different driver version to compare performances...3 series was good on my side until DCS 2.9

Thanks !

I think I managed to capture the oddball decoration zoom-in issue in a track (and on video) using the regular F16+Syria free flight mission.

Note the ship that appears at 10s(ish) and grows faster than ground movement and perspective would suggest until it stabilises at the proper size. It's subtle, but that's in part because of the angle — if you manage to catch the effect more obliquely, it will be far more pronounced.

@Tippis No, that is a map issue. I'll report it as such.

Nice.

OK, I also mixed the issues in this thread with this. My video of the same, also Syria, but from heights, it's more obvious:

But that's all from me in this thread...

[Flappie]

Syria does it too, then?

I tested with PG and could not reproduce. I've just reported Marianas and Sinai. I'll check Syria and report.
