Does anyone still get stuttering with many planes in multiplayer?

[[APAF]VR_Spartan85]

So, with my new rig, I am in awe at just how beautiful this sim is on maxed settings... and with crazy high FPS compared to what I’m used to, I’ve become a better pilot   well, so I like to believe  

 

running in in single player, I can quick mission with 16 aircraft, being bombers fully loaded or just fighters, on kuban, with ground targets, and everything runs very well...

however in multiplayer, at the home base, friendlies are starting up and taking off... everything ok,  getting to front line, ok, as soon as I encounter an enemy aircraft and look in its direction, FPS is constant but aircraft and looking around begin to jump... 

 

its strange, because a normal reaction to overload of objects in a scene would be frame rate drop.... I would think. 

 

Ive done all the “Jason’s graphic tweaking”

Game is beautiful, with acception of cloud pixilation and moving like they are being generated by a smoke machine... at a distance the look very nice...

 

any thoughts???

[ShamrockOneFive]

I've been having this problem for quite a long time now and I haven't been able to get to the bottom of why it is.

 

I have a strong system (Core i5 6600, 8GB DDR4, GTX 960, 250GB Samsung 850EVO) but not as strong as yours and I've been contemplating some upgrades to things like RAM and GPU over the next 12-months to help sort out some of my performance problems. That said, the multiplayer stutter seems to be independent of GPU, CPU, RAM, etc. Like you, I've noticed that my frame rates during those stutters remain constant but the whole sim seems to come to a standstill and then pick-up a few milliseconds later.

 

I've asked others if they have the same problem but not everyone appears to. This one would be too big of an issue for them not to notice.

 

So ... what's happening here. I have no idea.

[[APAF]VR_Spartan85]

I only noticed this after the 3.001 update..even on my previous rig . I sad   it’s very strange..

but I wonder if the devs experience the same issues?  

[HandyNasty]

In my case it had something to do with "terrain far details".

Somewhere is data folder of your game, there is a little file called "terrain.cfg". One can do some manual adjustments to that file, but for the whole explanation of how and why, I will refer to following link : 

 

 

 

Anyway, what I did  about a year ago in patch 2.00X is that I had increased "terrain far detail" manually in the terrain.cfg file, following the above-mentionned thread. This worked fine when horizon was at 40km. But when horizon is drawn at 150km since 3.001, I found that my RAM was bottlenecking suddenly and got micro-stutters. Apparently both my CPU (i5-6600k) and graphic card (GTX 1070) could deal with the extra strain of the improved graphics coming along with 3.001, but my ram couldn't (16gB RAM) and it was severely bottlenecking.

 

So I just diminished the settings in the 'terrain.cfg' file, and everything runs smoothly as before (and better-looking than before). I think one can also do that via the graphics settings, one option called "terrain far detail" or so... one can set it at *1, *2, *3 or *4. 

 

I found it out by using the same graphic settings as 2.012 for all options, and only reducing this 'terrain far details', as such I am relatively confident this was the origin of the stutters I experienced at the start of 3.001.

 

Hope this helps

Hi Handy,

 

I've already tried that fix actually and it had no effect at all and since 3.001 I backed off from 2x to default anyways. The only thing that is affecting performance in this case is the proximity to other aircraft. Once it gets to a certain threshold of multiplayer aircraft in a given radius, I start seeing very significant stutters. I've popped out to check my RAM, CPU, GPU, and VRAM utilization and there's nothing there that I don't see in single player when its smooth.

 

It's almost a bit like cheating (its not) because it sometimes gives me warning that there are aircraft around me that aren't necessarily friendly.

 

I'm guessing the number is around 6-7 aircraft when it starts. The more there are, the worse it gets.

[HandyNasty]

Yeah, I noticed too late that the OP mentions explicitly the stuttering is linked to player number at proximity in MP. I guess the stuttering I experienced had a different origin and as such my post kinda answers beside the question...

 

 

[6./ZG26_Custard]

If you haven't already done so, try reducing your settings for shadows from Ultra to high. I have suffered with stutter on a high resolution monitor (2560 x 1440) but by reducing shadows it seems to have eliminated stutter for me.

[[APAF]VR_Spartan85]

You know, I am flying on WoL kuban map, just bagged me two huns in my trusty old lagg.... but I have turned the shadows down to med.... and no stuttering

not much diff in detail... wonder why it affects it so much.. 

 

woot woot!

[[APAF]VR_Spartan85]

Ok I ended up turning it up to high, as med you can’t see your own shadow ?. 

 

I thik it’s still ok, I haven’t encountered a lot of planes but we will see...

That the graphics settings would have anything to do with this at all is a bit of a mystery to me. I'm still not seeing results either way.

[E69_Chipi]

I have the same issue.

 

Single player, with lots of AC around (career mode with high density) is very smooth. Steady 60FPS on ultra settings @ 6050x1200 (vsync ON)

 

MP even in not very populated servers I get stutters.

 

My internet connection is cable @ 125Mb/6Mb and I normally have a good ping to servers in Europe.

 

Tried to lower the graphic settings but the problem persists.

[SAS_Storebror]

Without intending to resurrect a zombie thread, I'm giving this one a friendly *bump* in the hope of either getting some dev to recognize the issue, or alternatively get someone who found a fix for this issue to enlighten us who still suffer from it.

Thanks for your attention!

[peregrine7]

That said it belongs more in the tech support section.

 

(I'm also getting this issue.)

[ShamrockOneFive]

I went up to 16GB of RAM interested to see if it would change the outcome. It hasn't. Same stutter.

GPU upgrade is coming next and I'm curious if that will do it or not.

[LuftManu]

Hello, I hope this can help you guys but with the system on my sig. I finally got zero to almost none stutters. I tuned down Visb. range to 130 km / Shadows to / Grass to Normal -> This one was the most noticable. 

Also from what I've seen, VRAM seems the most culprit about the stutters. Not everytime but 90% of cases in my part. 

Edited August 31, 2018 by LF_ManuV

[SAS_Storebror]

Visibility Range 130km... wow. I'm down to 70 already and still have stuttering. Shadow settings: All tested. Grass: All tested. Clouds: All tested. No difference.

System is i5-2500k @4.2GHz, 16GB RAM, GTX 970, game is on SSD.

I notice that there are two kinds of stuttering.

One is when you turn your head around (e.g. with TrackIR), especially noticeable when doing so in a crowded area.

The other doesn't involve any sight movement at all, it's just induced by closing in on other planes.

The frist (head movement) naturally happens more often, but is usually less noticeable.

The second (closing in on other planes) is a massive issue to me, as it causes like 500ms dropouts just when switching from the other plane's LOD1 to LOD0 or vice versa, which makes close digfights and formation flying a real PITA.

My fix for severe multiplayer stutter: 

 

- turn off ingame vsync

- force vsync on via nvidia control panel

 

It is gone now. 

 

Spec: i7 8700k, 16gb ddr4, gtx970, installed on ssd, win 10

That's what I'm wondering. I don't understand why SP and MP are different on VRAM but apparently it is.

 

My current card has 2GB which is too low these days so I'm going for 8GB VRAM on my next card and then we'll see. If that doesn't work then I don't know what else to try... I've already fiddled with VSync and other stuff like that with the settings.

[purK]

I have a decent PC and the same issues with stutters, the problem seems to be with my CPU. I was able to fix it by overclocking my CPU to 4.4Ghz & using a program called Project Lasso to force some settings on IL2 (High Priority, avoid certain CPU cores, etc...)

 

It also helps to turn some settings down in game. It certainly looks great on Ultra, but performance is more important in games like this.

[216th_Jordan]

Turning off threaded optimization in the nvidia game Profile seemed to help me. Can't guarantee its effect of course.

[Guest deleted@83466]

I've gotten a good results for local performance by using Adaptive V-Sync in Nvidia Control Panel and using Full Screen.  I think a lot of stuttering had come from the FPS dipping slightly below 60 hz and then the Standard V-sync keeps jumping back and forth between 60 and 30, which causes a lot of choppiness.  But with Adaptive V-Sync, that is no more.  When server numbers are high, you still see the annoyance of other aircraft jittering slightly (especially when they are in your gunsights!), but the issue is not on the local machine.

[SAS_Storebror]

I should say that I'm running my game on G-Sync equipment and everything is setup correctly for G-Sync so the usual V-Sync suspect is no issue for me.

I have tried turning off threaded optimization, change texture quality setting to "performance", use "maximum power" setting on Nvidia CP - all of this to no avail, the stutters stay exactly like they were before.

just a thought, this from me optimizing DCS on my rig (had horrible stutters), check core affinity assignment....my DCS was defaulting to single core... when all cores checked, stutters  gone... 

 

my BOS defaults automatically to all cores, runs great... (i know, not really designed/needs multi core, but still..)

how did you check core affinity assignment?

[SCG_Tzigy]

aahh

 

when running BOS, go to task monitor (cntrl alt del), processes, highlight BOS, right click for details,  set affinity

[TWC_Ace]

Experienced small stutters online after ages of not having them so i doubt its my rig. That is on KOTs server will check WOW and report.

 

EDIT: also experienced some stutters in other servers (WoW) but less. I didnt have them for ages and Im not alone so something did influence on that.

All was smooth yesterday and every day before for months...

 

I will see how it will be in next days.

can experiment, mine all on, see Krupinski above, he probably designated specific cores/CPUs with the Lasso app (this app/softaware sets it permanently, o/w it defaults back after each reboot)

Yep, did that already.

Years ago, for operating an IL-2 1946 dedicated server on an old VPS Server, I wrote a tool to consistently check, monitor and if needed modify CPU affinity and priority settings on processes.

I've used that tool to check various settings in BoS' thread "IL-2.exe", which normally runs on all cores with normal priority.

I tried giving it "High" priority, "Highest" priority and even priorities in driver levels (which are above "Highest" and usually inaccessible to user threads), and I tried assigning it to 1, 2 and all cores.

No change, at least not for the better.

On driver level priority you virtually kill your system when BoS is running.

On a single core, BoS is very CPU-limited.

Anything else is just like default.

I have stutters for quite some time now. 

It drove me to stop playing the game, as the career mod have the worst kind of stuttering. 
i would suggest to not waste time : If you search on the forums, a LOT of people have these issues, and spent A LOT of time trying everything. 

Lately I spent more than 30 hours just trying everything, from resinstalling my whole system, monitoring perf of each component, tweaking any parameters from NVIDIA, Inspector, the game etc.… (basically the work the dev's should have done), and the overall conclusion is there it is not hardware related. The problem is almost certainly INSIDE the game engine and the way it interact with windows and use resources. 

Even on the lowest settings , recomended by Jason I had stutters, and the most funny thing is I had even more than on my regular settings,  While running at 120 FPS.

Actually stutters appears for me on very specific moment : The first "Puff" of a canon fire on an enemy, any time I cross trees at less 100 metersheight, and When there is more than 6-8 planes Or ground object in the same bubble. 

My specs for the fun : i74590k @4Ghz / 16gb RAM DDR3 / GTX 970 4Gb/ SSD 500Gb (almost empty) …

For me Buying any new product from the IL2 series is a no go from now, and I will not recommend it to anyone until a real fix is there. I am a huge supporter of the work of 777 on the serie since day 1, and bought everything until now. My main source of anger is I paid for a product WHICH WORKED FINE , and not anymore due to game update, and the developers, despite all the good I think of them, do nothing about it.

 

I really hope I will see you again in the skies one day, but the solution is sadly not on me  ! 

S!

[TWC_Ace]

Today is ok. On almost full server. I hope it will last. Though its really interesting why some of us have stutters occasionally (rarely), someone all the time and someone never, no matter the hardware. It must be something with the net code or whatever, Im not an expert.

The full server doesn't matter. It's how many of those players are in proximity to you.

 

What's especially odd is that the stuttery performance is recorded directly into a track file which makes me think that, yes, CPU/GPU/RAM, etc matter, but there's something engine related going on too. For the stutters to be so consistently recorded into the track file and then to have them play back exactly is just not possible if it was purely a hardware issue. Every time you run a benchmark for example you'd get a similarly averaged result but never 100% the same... Here we do.

[SAS_Storebror]

In defense of the Dev's I have to say that stuttering for me was no real issue until about two or three weeks ago.

Didn't precisely keep track of that, because when it happens to you for the first time, you tend to think it will be gone next time you play, but it didn't - however the intensity of stuttering isn't always the same, that's why you don't immediately notice when it started and never went away again.

 

Now these two or three weeks fall within the latest patches lifetime, in other words: Right after Patch 3.005c came out, I definitely did not have this stuttering.

Gets us to the question: What changed?

I didn't change any settings until I started trying to fight stuttering, and I didn't suddenly play different types of missions either. So I'd tend to rule out "user error" here.

Thinking about possible reasons, driver and OS updates come to my mind.

I have rolled back my Nvidia driver by one and two versions, but it doesn't change anything.

What's left is OS updates.

I received the big "2018/07" cumulative Windows 10 update about two weeks ago, and right before that, there has been another big cumulative Windows 10 update before.

Could be related.

Or even not.

We cannot test, as you cannot roll back Windows 10 updates easily and you cannot roll back BoS updates at all.

Everything matters. BTW both yesterday (when i had some stutters) and today (when I had smooth gameplay) I was in intense dogfight, lots of planes near me. 

Also since Jason`s settings I have butter smooth gameplay, no stutters and thast why I was surprised I experienced some yesterday. I didnt for ages.

[SAS_Storebror]

Just back from a test sortie (online) and one thing I can definitely say is that stuttering during this sortie was related to the 2D HUD overlay.

Not always, but almost always when some new chat message or tech chat icon+text came up, stuttering occured.

This is particularly annoying with the tech chat: When you dive down on ground targets, a second before you hit the ground a tech chat message+icon pops up telling you that you're about to hit the ground - which in this case actually is true because while normally you would pull up in time, now you get a half second of blocked game, and then you're really at grass cutting altitude lol 

 

There's still other stuttering issues, but this at least is definitely one of them.

And I still could sweat that it wasn't always like that...

To me it is very strange how big the performance increase is for turning off the hud. It is kinda counterintuitive to me how much power it eats.

[montag]

Yes the HUD seems to really eat resources somehow. In VR turning off the hud leads to a ~5-10 frames per second increase for me.
