The problem with the weather and the stuttering of the game is still present?

Hello. I have upgraded my computer but I haven't noticed the problem yet  because I haven't been playing much.

Still stuttering for me and it does not happen at all on quick mission no matter how many planes or ground forces are around, only happens when multiple planes or ground forces are nearby in career, campaign and certain MP servers like Finnish. I'm playing in VR. 5800x 3080, 32gb 3800mhz ram. samsung 980 pro nvme.

 

GPU frametime is fine. CPU threads not maxing.

I have the same problem... No matter everything on max or on low. Play Reverb G2 at 50% SS set at Steam VR. i5 8600k @4,9GHz, 32GB Ram 3200MHz, Nvidia RTX 3800. SDD M2 Samsung 1TB.

 

Stutters are visible every time I met some planes near me, when I use zoom for the first time in some direction or a lot of things are happening on the ground below me. 

 

It is very noticeable when you look at FpsVR app. In the moments I wrote above there comes spikes in the CPU or GPU which cause stutters I guess. Frame times going to high for a second and here you go ;(

 

I really , really recommend to install FPSVR and check it yourself. It should tell you what moment  in the game cause it.

Hi,

 

I experience heavy stuttering when playing off- or online and getting close to city fires with the big rising smokes. Especially on the Finnish server when getting close to the front lines.

 

I am pretty sure it is a combination of high shadows setting and the moving smokes. When I set the shadow quality to low the stuttering disappears. But this is not looking good at all. Is it possible to use the new cloud technology also for the big smokes?

 

Are there more players experiencing stuttering when coming close to the front line on the Finnish server?

Ryzen 7 3700x

32 GB DDR4 @ 3200MHz

RTX 3080ti

 

No overclocking and playing in VR (HP Reverb G2)

 

A friend with almost the same setup (better processor) has the same issue with stuttering when playing at the Finnish Server when coming close to frontline smokes.

does it also shuttering on the other servers?

No, on Wings of Liberty it does not for example. Even when there is a lot of other players around it keeps running smooth. The Loose Deuce squad has an own dedicated high end server in a German data center. I will see if I can create a test MP mission with a lot of city smokes and see if I can reproduce the issue. Could be a good test.

Hi,

 

when I play Finnish in the morning or at noon, I hardly ever stutter. If I play in the evening when the server is full and players come and go, I have unbearable stuttering.

I've tried a lot but nothing works. The only thing that fixes it is turning off the hud. I don't want to give that up...

 

Regards

I have something that may or may not be different. I'm on Oculus Quest 2, 2000 x 2000 resolution (56%).  And this is on the Finnish server. I haven't played in other servers enough to see if it happens there too.

 

It's a permanent FPS drop that doesn't go away unless you completely restart the game. And the FPS drops to like 5-10.

 

It's not "random stuttering at different places".  It hits some logic issue once you get close to, what seems like, too many planes or ground units in multiplayer, that drops FPS significantly and permanently.

 

This never seems to happen when I first launch and join a server, even with multiple people around at an airfield when I first join. It ONLY happens after I've been playing for a bit. Maybe 5-10 minutes or so. And then get close to what seems like either another plane or ground unit. Or maybe being close to multiple units.

 

This actually makes the game completely unplayable to me in multiplayer, which is the only reason I bought it unfortunately. As a developer myself, I would love to help fix it if possible.

I've had the game for five years now and it always was smooth in SP and in MP. Until recently, about a week before Normandy was released, when my game wouldn't start anymore all of a sudden. I had to reinstall the game with a launcher file I downloaded from the website.

Since then, I have heavy stutters in MP. I did not change anything in my computer. It's really weird.

After some testing, I realized that my problem is related mostly or exclusively to the amount of players logged into the server I'm playing on, no matter what server it is (WoL, Finnish, TAW or Combat box; only Berloga is always smooth, but when I play there, there are always less than 30 player on it). The maps don't play a role, it happens on the Stalingrad map just as often as the new Normandy one. The stutters start when the player number approaches 40 and gets worse up to about 60 players on the server. After that, it doesn't seem to get any worse anymore, but at that point, it is already hardly playable anyway.
It's also not framerate related, since I have a stable70 to 80 frames, although I experience somewhat lesser framerates over all than what I had before the reinstall.
When I have the stutters, the game runs smooth for a second then stops for maybe a tenth of a second, then runs smooth for another second, stops again and so on.

It is really very annoying, especially because I had never had this problem before.

 

Edit:
I've now tried out the tip with switching the HUD off and voilà - a big reduction in stutters. 
But how can a chat overlay cause so much reduction in performance, I wonder. Some bad programming, surely...

Hi there,
I have an odd problem.
I can play the game for approx 1hr without any issues (140 fps 2560x1440p@144hz), then after that hour the game will stutter badly and the fps drops to 80fps.
This only happens on multiplayer servers,
Starting the game again doesn't seem to help, but rebooting the PC does, for another hour!!!
I run a 10700k with an RTX 3090, and 32gb of RAM.

Thanks.

[RossMarBow]

This is a 5800x and a 4090 in multiplayer

this is the same pc in single player

this is a 5600x and a 5700 xt in single player

this is a 5600x and a 5700 xt in multiplayer player


this is rainbow six siege multiplayer running on a 3770 and a 380


something is causing stutters 
theirs no specific cause for it other than multiplayer
its not ping, its not hardware, its not server specific, its not smoke, its not lots of players on the server
its something specific to how the game handles multiplayer

graphs are produced using amd OCAT which works on all hardware

 

 

UPDATE:
combat box server with 4 players = no spikes

 

Finnish with 24 players = spikes

 

Berloga with no players only AI = spikes

 

 

Server:
WOL no spikes 7 players
EU official no spikes 6 players

 

CB training however has bad spikes with 1 player

 

 

EDIT:
This is Finnish after changing smoke vs combat box

It seems to be cause by spawn points
as CB training has the most spawn points and the biggest spikes
followed by Berloga
then Finnish

 

I have a separate thread in complaints with more updated information. 

Further testing on combat box showed that spikes occur when the server is overloaded.
And its not purely caused by spawn points. All though spawn points do seem to create a lot of load. 
Even if overloaded messages aren't showing up.
Every single map I play I'm now running OCAT and posting results into CB discord for that map.
A new map chefs choice was interesting it had quite a lot going on and big flights on single engine AI squadrons doing bombing runs, but it was running smooth.
Compared with the previous map which had AI bomber squadrons and maybe some other things going on that caused a lot of lag.

I have also ruled out specific maps causing issues. 

 

Edit:

Further updates are located in this thread

Hello,

 

I don't know if this thread is still alive but I would like to see if anyone has this issue as well.

I fly exclusively with a buddy in multiplayer missions. Only the two of us as we are not very good and don't want to mess up other players experiences. 

The issue is when I start a server I have know problems with stutters but when my buddy starts a mission (seemingly only Stalingrad summer maps) If I look out to the side (TiR) at the ground I get very precise timed micro stutters. If I start the exact same mission smooth for both of us. 

I have now settled on game vsync on and full screen off. Still stutters. 60FPS and 92% roughly GPU ram usage. (it used to be 98% but I turned somethings down to allow more room for heavier loads) 100+ Mbps connection.

I have read lots about it and tried I'm sure every suggestion posted. I don't think posting a video would help as we have all seen the effect.

We both run fairly high end hardware mine is a G15 i7 11800 max out 4.6 - 32GB ram and RTX 3060 6GB Vram. My friends' is slightly better.

 

I don't want to start the whole discussion over again but thought this might be an new issue and some one might have it too. 

We both have the same missions. No file transfer when joining just straight to the splash screen.

 

If anyone else has this issue and solved it we would appreciate any input....thanks

Now, after several uninstall/reinstall sessions, it works again. This time I deleted every registry entry I could find after the uninstall and installed into another hard disk in my computer. Strangely enough, that did the trick.

have not played since Nov. was busy playing dcs multi thread on a i7 10700f with a rtx 3070 i just installed a external ssd  to avoid any more heat to a ? design r-11 and no issues or stutter there, even with everything turned to high or ultra with high framerates smooth as babys bottom , so i set it up the same here and i get not really stuttering but it hangs up and im getting frame rates about 80 im playing but this seems familiar! i need to check my defender and Malwarebytes to make sure its not excluded  you can tell if there is a pattern to the lag or stutter  thats would be your virus ware scanning  also im playing SP

Hi, Me and my friends have a stuttering problems with MP in Il2 last days. FPS are stable, frametimes also. VR and pancakes, same problem. I don't do SP, but checked there and have same stutters. It is very noticeable during rolls. Servers like WoL, CB and others. You want me to put some more information to take a closer look on this?  

[Gora_]

Does anyone can have a word on this? Do you have similar problems?   

[Gora_]

Does anyone work here?

@LukeFF

 

I also have to agree with this poster. The last few updates have introduced lots of stuttering and frame drops despite having mostly stable FPS. Performance in VR is probably 20-35% worse since this time last year and lots of people are experiencing the same thing. Can the team take a look at these performance issues? Can they make improvements to VR performance?

[Gora_]

My hardware is i7 13700k, 64GB RAM, 4090, M2 drives, Quest 3. Stutters at native resolution at 72Hz during rolls on almost every server. What do Devs need more please tell me and I will provide information.    

 

DCS is silk smooth at the same resolution BTW.

I noticed some occasional stutters too, in SP no VR. That with a 4080 super, and i9 12900K, 64GB DDR5.

Seems related to complicated missions where timescale only works at 2x, and seems to happen when more planes, etc are spawned in.

(with former 5.100 game versions it seemed less of a problem).

Have you tried to install ISLC

I found this as a recommendation in IL2 forum and for me it has improved the stuttering.

Just leave all the config as is, and changeg polling to 4000 ms.

Installed this last night and bingo, all the stutter and tear is gone! With ultra graphics good fps and silk smooth movements. Thanks!
