19//Moach 431 Posted December 9, 2019 Share Posted December 9, 2019 (edited) Allow me to add something (possibly) constructive here. I have noticed yesterday, once a mission had ended, and the message "mission will end in a minute" or similar had come up, the stuttering had all but completely stopped. It could be then, that whatever causes this phenomenon is not really in the netcode itself, but perhaps it has more to do with the mission logic. This strikes me as a plausible guess due to how once a mission stopped tracking objectives and stuff, the problem simply went away. And yet, at that same short interval, the multiplayer environment (sync'ing of aircraft positions and such) still appeared to have been active. It is also worth noticing that in that same server, while the mission was "young" (having just started), the stuttering was either not present at all or so mild it could not have been noticed at my present FPS. The server had been about >80% full throughout the whole mission. It's player population did not seem directly related to the noticed amount of stuttering. But it was only after some time into the mission, well after most players had finished joining back in, that the problem gradually grew. First into noticeable, then all the way into performance-crippling shortly before it ended, abruptly, once the Germans had completed the process of thoroughly kicking our allied asses. In that short time between mission end and server "lights-out", there was a marked absence of the stuttering which gradually escalated up until that point. Thus implying a possible connection between mission logic and the stuttering problem. This would explain a few things, such as why the devs cannot seem to replicate the problem, and also why some servers have it more than others. Plus, the variation in severity might account for the seemingly random set of settings variables reported to have some effect on it - by coincidence, if not by actual relation. Multiplayer servers aren't exactly clean trial grounds for scientific experimentation. Of course, from symptoms alone, this is just an educated guess. But well, who knows? Maybe a guess might lead to something. Only one way to find out... Edited December 9, 2019 by 19//Moach 1 1 Link to post Share on other sites

SCG_ErwinP 506 Posted December 10, 2019 Share Posted December 10, 2019 (edited) IMO, stutters has bond with new maps. What is happening in my side: TAW is running good, without stutters while running old maps (at moment) (I didn't play too much time in this campaing); Combat Box has lot of stutters (micro & macro) (running new maps most of time); New maps has lot of (big) cities closer one each other. Stalingrad is a big city but it isn't too much detailed such cities at Rheinland map Potencially, new stuffs as said by Alonzo: On 11/30/2019 at 11:48 PM, Alonzo said: The latest release of the game has a ton of new stuff in it, including much asked for increases in spotting distances / render range, new building rendering, etc etc I hope devs bring good news soon!

Ketzoh 2 Posted December 12, 2019 Share Posted December 12, 2019 (edited) After hours of testing different settings without success, i maybe find a little solution, at least for me. My Screen has a Refresh Rate of 60 Hz, but in the Nvidia CP i could lower the Refresh Rate to 59 and 50 Hz. So i set it to 50 Hz and in the Game Settings turn Vsync On and Frames set to 50. After a quick Test on Combat Box i can say that the stutters are almost gone. Edited December 12, 2019 by I./ZG1_Ketzoh Link to post Share on other sites

Olaf-A 0 Posted December 17, 2019 Share Posted December 17, 2019 Guys, please follow Jason's note at the first page to pinpoint the issue cause: NOTE: If you are on a server with stuttering, please do the following.- Record a track of the stuttering.- Please tell us if the track stutters when you play it back.- Note how many users were on the server when stuttering occurred. - Save the mission files (they are downloaded to your install) so we can examine.

I am happy to support the WW2 simming niche, so very much. It is sometimes not cheap, but this is what I love. Therefore, I do understand things are often more difficult than they seem, and I do accept it when concessions have to be made. If making the game better and pushing the boundaries require some risks and cause problems - I accept that, because it serves a purpose. BUT it has been few months now since the issue was (re-)introduced, not just the christmas break. You can see the team and Jason himself active in the forums, answering to questions and commenting on other stuff - almost instantly, I have to give it to them - but just ignoring this one. Even with all the spammy tagging. It's natural you become impatient and frustrated. It is not that I was worried about the team's work pace or methods. I now worry that they actually might not be working on this at all. We are not being neglectful. Comments like this are not helpful. If we were neglecting this issue this thread would not exist. I have not given an update because I have nothing new to add and very few of you have done what I have asked to help us solve the issue. We have worked on some new things to try and alleviate the issue, but we still don't know the root cause. It is very difficult to duplicate all the different conditions internally under which you may experience these. And I say again, if you have smooth SP experience and have these stutters in MP, they are not caused by graphics settings on your end. It's something else that's why we need to see videos and tracks.

Alonzo 2251 Posted January 14, 2020 Share Posted January 14, 2020 You could also try TacView recording, which will show how many objects your client is processing. My suspicion is that with the longer aircraft visibility distances (something that multiplayer pilots have been asking for for a long time, and which is a massive boost to the game, really great stuff) the server is sending more information to the game clients. Kind of obvious really, the 10km "bubble" is no more, so there's a lot more stuff going on. On Combat Box we have tried hard to optimize the maps by switching off units when no players are nearby, but on a busy server this might not help since everything is mostly active most of the time. Anyway. TacView might cause stuttering in itself because it's extra overhead, so don't confuse the issue, but it will show all the objects your client is processing. For me it's sometimes a surprising amount of objects including stuff very far away. This might give you an idea of if there is a difference between WoL and Combat Box for raw "amount of objects" or something. Another thing you might try is some sort of network monitoring for the amount of bandwidth/packets used by your game client. Is it more bandwidth = more stuttering? Or no correlation? You want to do very specific monitoring though, not just Windows "network bandwidth" for the whole machine. I'm not sure of the right software to do this but I'm sure there is some to just look at the data to/from the IL2 server. 1 3 Link to post Share on other sites

VBF-12_Snake9 320 Posted January 15, 2020 Share Posted January 15, 2020 6 minutes ago, VBF-12_Snake9 said: Well something very weird with this mission. As I stated earlier on 1-10-20 me and two other wingmen flew this mission and we all noticed heavy stutters. Thus the above quote. Then on 1-11-20 flew the same mission twice with the same wingmen and all of us noticed the stutters were completely gone. Great! We thought maybe the mission had been tweaked. We flew again on 1-13-20 and again no stutters. Great! Well tonight I jumped on tonight 1-14-20 this mission and noticed right away the horrible micro stutters were back. I took a quick flight and landed to restart my computer just to check it wasn't me. Restarted and logged back in and took off from the same airfield a-92 down south. I noticed the stutters were better but still not quite smooth. I circled the airfield until a saw a 47 take off. As soon as he went wheels up the micro stutters were awful once again. Very confusing. So I landed and wrote this post up. Again this is the only mission that I have had micro stutters on. All other missions are smooth. What makes it even more confusing is that we flew this same mission for several days smoothly until tonight. Very confusing. I believe it has to do with the netcode or something like that due to when the 47 went wheels up the stutters started bad again. But why would it be just this mission and not the others? Very confusing. This was on combat box. Maybe helpful. Link to post Share on other sites

I'm not sure of the right software to do this but I'm sure there is some to just look at the data to/from the IL2 server. When I fly on Combat Box, regardless of player numbers, I get at least some stutters. They are noticeable worse on the BoBP map, but they still occasionally occur on the Kuban map missions. The worst offender is A Bridge Too Far. I get 2 to 3 times as many stutters on that map as on any of the others. Ruhr Pocket is probably next worst. Crossing the Rhine and Battle of the Scheldt are pretty smooth over all. This doesn't mean there's a problem with the missions per se, but there is clearly an impact from the mission design standpoint on how bad the stuttering is. But the root problem is why is there stuttering in the first place? 11 hours ago, VBF-12_Snake9 said: This was on combat box. Maybe helpful. I think I was on this mission with you, saw you in the chat. For me, that mission had stuttering but a the 'normal' level for me; not really frequent or bad. So even people who have the stutters, flying in the same mission at the same time, can see it differently. I have tracks, video and mission files from A Bridge Too Far last night where I had the stuttering, I will upload if I can, but my upload speed is highly throttled where I am so I will have to try and do it overnight at some point.

RavN_Alienzo 41 Posted January 21, 2020 Share Posted January 21, 2020 There's been an update and I made some test about stutters. Before update there was a 100 fps with drop to 50 fps at high alt (Rheinland map). At low it was 80fps to 40fps. Now it looks better, but it should be noted that there were only 18 people on the server. Link to post Share on other sites

RavN_Sone 98 Posted January 21, 2020 Share Posted January 21, 2020 I did a little first test, on Wings of Liberty (50-70 players online) for most plausible effect. The positive change is significant, performance was a lot better. It seems a little stutter here and there still happened (it always had with WoL), but those nasty framedrops were not noticeable. I noted that, while before today's update there had been huge frametime spikes (from ~7 to 16 or sometimes even 30ms) and this was when the stutters showed, today frametime variations stayed around +/- 4 ms. This was not a reliable sample for final conclusions, but general message is that v4.004 seems to have helped. Link to post Share on other sites

Both missions on new bodenplatte map. The situation is much better now. Stutters are more or less - gone, can be still seen sometimes, moving around with edtracker pro is much smoother but I can still feel it its not smooth as before big "visibility patch". Still, now is playable and is much better online and most of the time i feel my head tracking/movement is much smoother. FPS is stable.

In SP quick missions when I look around (I use the mouse for this) it's buttery smooth even if I'm not hitting my max frame rare of 100fps. In career or any scripted campaign mode with the same fps it's very laggy when looking around. I have a gsync monitor high end CPU and gpu more than enough ram but I can't get rid of it.

There is a separate one for stuttering in single player modes and you may find more information posting there, from what we can tell there are separate issues causing the MP and SP stutters. The recent update to texture loading seems to have been very helpful in MP modes at least, I have not played the Career mode in a while. Career mode and scripted campaigns are going to be more intensive than a QMB mission - there is more going on, more to render, more enemies to keep track of, etc. Post a screenshot of your in-game graphics settings over there and see what other people with similar setups are experiencing. You may have to reduce some of your settings to get smooth performance. Link to post Share on other sites
