Fast moving aircraft still juddering during multi-player replay

[AlpineGTA]

Even though it was marked as fixed after the last patch, I'm still seeing juddering of fast moving aircraft when watching a multi-player track replay. I haven't checked if it's still doing it whilst flying or in single player, I only noticed it when watching back a track replay from Enigma's cold war server. Every camera view I tried: F1, F2, F4, Ctrl+F2 was stuttering. All aircraft, not just my own were affected. Slow moving helicopters weren't stuttering.

I could upload the track but it's over 50MB.

I tried a MP track and I cannot reproduce the issue you describe with F1, F2 and F4 views. Is your DCS updated to version 2.9.0.47168?

Jittery RCtrl+F2 view is still affected though, and it's reported already.

Don't forget LShift+J toggles camera jiggle.

Yes, I'm running 2.9.0.47168. I'll test again and see if I can save a shorter track to upload.

Thanks.

Your track plays fine but I was able to reproduce it flying an instant action mission using the F1 on Syria. As soon as I take off the jitters start, on all views. However, a few seconds after making the left turn after take off and levelling out the jitters stop. I wonder if it's to do with graphics settings. I see the jitter if I use FSR (I'm using an AMD GPU), but if I use MSAA and watch the same replay I don't see the jitters.

Screen shot of my graphics settings when seeing the jitter and track attached.

Is it solved? Didnt notice it in the changelog, my foul maybe, I’ll check it.

It's in the changelog:

MP. Aircraft and missiles in flight "jitter" back and forwards - fixed

@AlpineGTA I see what you see in your track. However, as soon as I take control over the track, the plane stops jiggling.

In the attached track, I did the takeoff part: no jiggling. You should check your rudder axis. Maybe it's responsible for your issue.

Yes, it doesn't happen whist I'm flying, only when I'm watching the track. I don't think it's a rudder issue because you can see the aircraft juddering forwards and backwards if you look at it side profile using F2. And in F1 view looking through the HUD, the whole view is shaking, like your skull is being rattled violently. Also, when I originally observed it on the ECW server track, all aircraft that I viewed were doing it, not just my own.

Like I say, I think maybe it's a graphics setting issue, I don't see it if I'm using MSAA. What graphics setting were you using when you saw it?

Anyway, it's not a big deal, it seems like a minor thing that I can mitigate with different settings that I only use when watching back replays, it doesn't affect me whilst flying, which I use different settings for anyway. I just like to crank everything up to the max on replays so it looks pretty!

Thanks for looking.

I've just noticed that my Syria track is also affected.

I'm now trying to reproduce it in any other mission. I tried over Caucasus but it does not do this.

I did a short F1 flight on Caucasus and it wasn't affected either, I've only noticed it on Syria. I don't know if other maps are effected, I'll have to check.
