Okay I finally figured out what causes the problem for me.
This mission by Dixon: http://steamcommunity.com/sharedfiles/filedetails/?id=272240034&searchtext=training+redux

As soon as i unsubscribe from that, the lag disappears. Something weired added into that one, I haven't unpbo to see whats inside, can't find the mission in the convoluted steam folder system.

ICEMAN can you please suggest to whomever is in charge of steamworks, to make all subscribed missions downloaded to a folder called e.g 'steammissions' in arma III root folder!

I can also confirm that unsubscribing from steam workshop missions gets rid of the issue.

I have the same issue. This did not happen immediately after the latest stable update but sometime between then and now. I was able to host locally and play just myself MP missions no problem. Then all of a sudden this started showing up this evening.

I tried Vanilla as well with no add ons loaded.

I have now deleted both 'arma3' and 'arma3 other profiles' folders in my documents to let the game create fresh ones when I start up the game, but the problem still persisted.

I then completely removed arma3 from steam and did a reinstall, but the lag is still there.

So the culprit may very well be the workshop missions.
Where exactly are they stored? so I can take a backup before deleting all of them.

EDIT: Maybe everyone should copy the names of the missions before deleting so BI can look into it. Take a screen shot of steamworks scenarios list ingame.

I have been silently browsing this thread for a few days and I have the same problem and what Oulabird said may have something to do with it. Maybe it has to do something with workshop addons or something? Maybe with the default profile, once you download something off the workshop it changes something that, after a recent update, was changed in the update and now is screwing something up? I don't know, just trying to put some thoughts in to try and help this get fixed quicker.

I don't know whether to be relieved or horrified...We have a cause but I now have to test the hundreds of missions to which I'm subscribed separately.

Can confirm also; no idea yet which mission caused it but unsubscribed to all workshop items and back in business.

Default profile also working with no workshop missions present.

This happened to me once I registered for a workshop mod called Armory Original+Modern [Beta] and I have deactivated this workshop mission and it went back to normal.Hope this helps

Oulabird nailed it! I have just unsubscribed from all Steam Workshop objects (several missions made by other players) and all issues are gone! No more loading screen and no more lag blip!

I have.

I've also used (successfully) many mods, but only with this latest update has the regular flashing screen problem occurred exactly as described elsewhere. For the record I'm using a non-default profile as I don't use my steam ID as my in game Arma name.

The only mod I've used for quite a long time is VTS Weapon Resting mod. I tried out iBuild recently but it has been disabled.

yes me too, a metric ton of them.

My friend who hosts our co-op games has been getting this bug for over a month on Dev branch. It is only ever the two of us in the server. He gets the loading screen, and when that happens I experience massive desync for a few seconds. He recently went from Dev to stable and back again, which got rid of the loading screen but we both still get lag skipping every few seconds.

Don't worry, we are still trying to fix this. The issue is that we are unable to reproduce it. Have you all used community addons in the past?

its better yes, but the lag blip is making thing difficult to host, as it brings down the FPS and creates desync significantly.

Creating a new profile removed the loading screen, but the lag is still there every 14 sec. Other player notice the same lag if they are in a vehicle that I'm driving. They can also see my avatar lag when I run around.
Good ping, no desync.

Same as everyone else. Changing from my default profile from in game removes the loading screen opening every 10 seconds but there's still some minor cyclical lag.

Not sure if it was default but certainly reasonably old.

My main profile (which makes the loading screen appear) is NOT the default profile that was automatically created by the game right after installation. I didn't like the game using my Windows username, so I created a new profile with my prefered ingame Nickname shortly after installation back in 2013. So the profile I'm having problems with is about one year old and was created by me using the menu buttons in the main menu of the game (Configure -> Profile -> New). Hope that helps.

Thank you for the data, we are currently analyzing them. Could you please confirm that this behavior (the loading screen) was happening on profiles which were default (created by game) and rather old?

I can confirm that even with a new profile there is a short "lag" or stutter every 10 seconds. Barely noticeable, but it wasn't there before and it appears at the exact same interval.

P.S.: My profile folder is almost 300 MB, that's why I can't help here. Upload would take several hours with my slow connection.

Seems like you are using the standard profile that was automatically generated by the game. In that case you should upload the whole folder named "Arma 3" under "My Documents".

The folder should include some subfolders (missions, MPMissions, Saved, UserSaved), as well as the two profile files: yourname.Arma3Profile and yourname.vars.Arma3.Profile

Uploaded ...it's big though (.zip not .rar I'm afraid.

I know, my mistake, I already corrected the path in my previous comment.

They are just in My Documents/ARMA3 not a separate profile folder.

In the location you initially suggested I have only MPMissionsCache, SteamMissionsCache, SteamPreviewCache, and the rpt files.

Made a video of the original issue as well. Upload just finished:

This is an interesting news! Could you be please so kind and upload your profile (the one which is causing the problems)? You can use some file-sharing service like Dropbox. If you mark your comment as private before posting, only I and moderators will see the link. Thank you very much in advance.

The profile folder should be located in your Documents folder

Thanks for the profile in the link, but I still cannot reproduce it. Is it possible to put your entire profile folder into a rar archive and upload it? Thank you!

Another question, does it help when you create new profile?

same here created a new profile and we are all good. however there is a small lag blip every 10 sec where the screen would pop up. how ever that may have always been there not sure.

New profile helps. Stutter still present at the same interval but load screen has gone -vastly improved(playable but still enough to be somewhat frustrating).

Uploading video of the original issue to youtube atm, will post link when it's done.

Just tested: The issue is gone when using a new profile! After changing back to my old profile the issue returned. So this seems to be profile related.

I have tried removing the squad URL from my original profile, but that didn't do anything (issue still there when using my original profile).

Hello, we are still trying to reproduce the issue, but so far with no luck. Although we are already on data lock, this issue has high priority in internal systems and will be merged into Stable update as soon as it gets resolved. The problem is that we cannot even reproduce it, not speaking of fixing. Also a video would be really nice to have some evidence of what exactly is going on.

Thank you all for your info, I hope we'll move forward with this.

Apparently it has some effect at the client side too, described by my client as:

" it's like connection has been lost or lag - physics seems to keep going for a few seconds, then everything "skips" back to it's actual server position. This means vehicles and other physx objects literally float off the ground then pop back down again, while infantry just seem to skip back in time. No indication that connection is suffering (no link icon or messages)."

Clean rpt file uploaded: arma3_2014-10-20_23-45-05.rpt
Game started without any mods. Went directly to the MP Editor (Play - Multiplayer - New). Created a new mission named "test" on stratis. Placed down a single unit (player) and went to "preview". Right after mission start the issue started showing up every 10 seconds. I noticed several error messages in the .rpt file, but don't know what to make out of that.

Same issue here since the last game update: Loading screen pops up every 10 seconds. This only happens when I'm hosting a game, for example in the MP Editor (Play - Multiplayer - New). When I start the editor directly from the main menu, the problem does not occur. I can also join and play on dedicated servers without any problems, so the issue is definitely related to local MP hosting. Since I do most of my editing for our clan in the "MP" editor, this bug is really annoying.

Problem occurs immediately.

Both LAN and Internet hosting.

Tried with 0 clients and 1 client occurs with both.

Verified not occurring in single-player missions.

I completely removed my ARMA 3 install and reinstalled fresh last night (It had been installed since alpha) file verification all ok.

If any further information/tests would be useful I'm willing to try.

Still occurring in Dev-Branch too.

Hey Iceman. I'm going to record a video of the issue and upload it to YouTube. Sit tight.

On another note, I think the Priority and Severity of this issue should be changed since this is hindering our gameplay.

Thank you! Is it possible to provide more info? How many clients are connected? Is it via LAN/Internet? Does it happen right from the beginning? Thanks a lot for the answers.

@Iceman can you give us an update on this situation please?

I don't see anything in common from your rpts. Could you please try to reproduce it again on Stable build, without any mods and on mission Escape from Stratis? Also, could you please upload your DXDiag files (name it with your nickname, please)? Thank you a lot.

I started getting this last night, only when I host a mission with and without addons as soon as the mission starts, its like every 10secs the screen goes to the loading screen for the mission.
Theres no lag its like you alt tab out of the game and when you come back if you were moving like running when the screen changed your character finished his run, no lag just goes to the loading screen for 1-2 seconds and then goes back to the game, then in another 10 or so secs same thing.
You simply cannot host a mission for yourself now, it happens with any mission, i tried with heavily scripted missions, and with missions with nothing but placed squads and a player.

Uploaded further data as requested.

my .rpt ,too. with or without mods same issue. Hope would be fix nearly.
thx

I tested it out with other players, they dont get lag when that loading screen appears.

thanks for posting guys. when i pull back to vanilla it still happens.

Same issue, uploading rpt file. As an aside, this was happening on devbranch, moved back to vanilla and all was ok, now doing it on vanilla too.

Your rpt is of no use cam7667, you have disabled logging.

Have had the same problem for the long time on dev branch. uploaded rpt log.
These lines repeats itself over and over in my rpt:

When i look at my RPT file it is almost blank. Other people are having this issue. This only happens when i try to host a mission on my machine. It works in SP and on other peoples machines and servers. This is the entire RTP file. Oh yeah this was run with no mods total vanilla.

Ive uploaded my own RPT file. Im having the same issue.

Hello,
thanks for bringing the issue to the feedback tracker. Could you please upload your newest rpt file?
C:\Users\<Name>\AppData\Local\Arma 3\

Also, does it happen all the time? Do any other clients see any abnormalities as well? Thanks for the anwsers in advance.

Duplicate of http://feedback.arma3.com/view.php?id=17347

@cykuan I am unable to repro. Please, if you are still affected by that issue please create a separate ticket.
Thank you.

neokika: Yes, it is seems to be fixed (I've tested it for several days, no problems), thank you! I think it is safe to close this issue now.

(What would be good (for the future) is to be able to pass additonal user parameters as (for example) BIS_fnc_addStackedEventHandler does and, maybe, use user function return value as a new delay value).

onEachFrame is now broken. Draws only 1 frame and doesnt seem to loop anymore.

The cause of this was one version of CBA. Therefore not related. Happy for this to close.

Fixed, expect it on Dev Branch next week.
Your example code is problematic because it tries to spawn core modules, try instead:

MyFunc =
{

hintSilent str [time, _this];
[format ["MyFunc_%1", time], compile format ["%1 call MyFunc", time], 1] call BIS_fnc_runLater;

};
[time] call MyFunc;

And it should run forever.
The problem was automatic termination of BIS_fnc_loop in case there were no more items to execute.
Please confirm whether it is solved.
Thank you.

@sms Is this deemed fixed? Thank you.

MaHuJa: Sorry about that. Changed to public.

neokika: Thank you! Yes, my real code spawns harmless vehicles like "Land_CncBarrier_F" etc, not modules. The point was to make something that takes long time, then call BIS_fnc_runLater for onEachFrame to interleave with BIS_fnc_runLater execution.

"This video is private."

You probably want to change that to unlisted.

See my related (duplicate) issue for another explanation of the issue and suggested fixes

No need to go for a last model throttle. Giving some sensitivity and linearity curves also for keyboard users could help. Some racing games let's you adjust how fast your wheel turns.
Or give us an option for keyboard to rise and lower the throttle with steps. For example there would be 10 steps and each time you push Q or Z (could be separated from the current keys also) it goes one step.

I think the different views points should ideally display the weapon in the true position always.

ArmA should had this sorted a looong time ago , to recognize someone that he is firing from the hip or aiming down sights

Hell even TF2 sniper has that , you can easy see if he is aiming or not

The problem here is that 1st person view doesnt match 3rd person. Current 3d person shows player aiming down sights at all times even if he is hip firing. Bringing weapon chest level when not in ADS, just like 1st person shows, in 3rd person would already make it less hostile and more distinguishable for an observer.

That's why there is a raise/lower weapon function in the game. The people should start to maintain discipline, that is the problem on most of the public servers.

I rather have animations sync. If the player has their gun up, other players should see their gun up.

Maybe I should specify, that the weapon should not be completely lowered (as with using the weapon lower function), but just slightly lowered so that it would not be pointed directly at whatever the player is looking at.

If I where to have to raise and lower my weapon manually to look at my teammates it would become tiresome and the clunky nature of raising and lowering your weapon (especially when crouched) could get you killed.

Your gun is still "up" just not aimed directly until either fired or aimed down the sights.

It's just a small feature that could make a big difference in terms of immersion.
