Clients jitter on listen server

anonymous_user_df69a606 · January 12, 2016, 1:00pm

… but not other way around. There are already several Answerhub entries adressing same problem, but none of them offers a solution.

As already mentioned in those other entries, problem exists in simplest kind of Setup. We have tested on different hosts, with different connections and different projects. Multiple Instances on one machine, Lan and internet. We have profiled network traffic and disabled all animation. Its just seems as if there is a interpolation problem in movement processing for characters on listen server. Every movement on every Client was smooth in every test. Capping framerate at 30 make problem very hard to identify but it still exists.

Here is a video with a comparison: https://dl.dropboxusercontent.com/u/2595963/clientServerComparison.mp4 . Please notice, that difference is much more recognizable ingame than in video because of video capture issues.

Is there any solution or answer to this?

Hey, we are also experiencing exact same issue (as many people) any news on this bug?

Just to reconfirm problem: listen server experiences client jittering in their movements while clients themselves have no jitter noticeable on their side. So listen server(host) is one experiencing this only. Very strange.

I’m having same issue. Also as shahrizai said: client jittering can only be seen from listen servers viewport. listen servers pawn seen through viewport of client itself doesnt jitter.

Updates on this issue would be awesome.

Is this issue fixed on 4.11 preview 4 ?
If not can we expect it to be fixed in 4.11 ?

Hello.

I have been having this same issue as well. Is there a more specific ETA?

anonymous_user_33800a51 · February 2, 2016, 5:20pm

Hi all,

There is no timeline for when this will be addressed. There is no reason at this time to believe this will be fixed in time for 4.11 release. We will post here when we see any change in bug report’s status. Thanks for your patience.

I also experience this. Can’t wait for a fix

Chosker · March 16, 2016, 11:17am

I’m also having problems with this, a fix would be nice

Atheist91 · June 1, 2016, 12:55am

Hello.

Unfortunately, we also have this issue in project. Any news about fix?

Sean_L · June 1, 2016, 2:06pm

Try opening a copy of your project in 4.12 and seeing if you are still experiencing jittering. Many instances of this issue can be linked back to fact that meshes or other components that are attached to capsule are not being smoothed because capsule does not have smoothed position. Give it a shot in 4.12 Preview 5 and let me know if you notice any changes.

I’m using 4.12.5 and having same issue.

Sean_L · August 8, 2016, 12:48pm

this also might be affecting animations too. it seems like tickrate of animations for listenserver and dedicated server are almost halved compared to default values. this may or maynot be linked to this problem
