Thanks, no I'm referring to the normal motion of all road traffic generated by P3D, versus for examplel airport ground traffic and GSX ground vehicle animations which are totally smooth and appear to run at the same frame rate as the rest of the sim.  It's always been this way for me since road traffic become an option, no matter what hardware or version of P3D (from 2.0 up to 4.5).  To me it acts like it's running at a much slower with an variable frame rate, so is as I say, jerky, and it really is pathetic for...2021.   

No, I didn't notice that in V5. Or in 4.5, for that matter. I guess I don't spend much time watching the road traffic. But, like I said, I'm sure the amount of traffic has very little impact on the frame-rates in V5. I don't think it was like that in 4.5. For me, that's a sign P3D's “old code“ is being improved, even regarding minor aspects.

I don't either, but it's obvious and has been forever.  Does anyone else see this? or do I have something setup incorrectly which I suppose is slightly possible but as I say this behavior spans multiple PCs, OS', and versions of P3D.  As mentioned, performance impact is not relavent for me as I have ample CPU headroom now.  No need to reply Dimitrios I don't think you have anything more to add, but others here might.

Road traffic works fine for me in v5.

Did it work fine in v4.5, if you were ever running v4.5?

Yes.

for me strangely, it depends which addon airport i start at , some give me stutters some dont , and thats with default or chris bell traffic addon for black marble , weird !. i just turn it all off now until a solution arrives!

Interesting observation.  You're saying if you're at a specific 'addon' airport when you observe road traffic outside of that airport it may be jerky animation.  Have you noticed smooth road traffic animation when you are at a default airport?

sadly i didnt try , yep ive been having the issue for a little time, could it possibly be a conflict between addon airport embedded traffic and p3d or another addon traffic , maybe they are fighting for my black marble vector roads who knows lol  

I remember reading a while back that the traffic is like that due to the refresh rate update of the traffic, it was coded this way to reduce CPU calls, thus improving performance. (This has nothing to do with your monitor refresh rate)

I can also confirm V5 traffic has far less impact on performance.

That is exactly what it looks like to me--limited to about 12-15fps, or call it refresh rate.  

Did they change the frame rate of the traffic in V5, so that it runs at the same pace as the rest of the sim?

That I'm not sure about, I will have to load up a flight and verify.

I performed a search, but I couldn't find any reference to this. Do you by any chance still have a link?

No I don't, it was years ago. But it does make since, as an example if the traffic is updating 3 times per second vs 60 times per second this leaves more processing power for other tasks. Which was clearly needed in V1-4 as there was a large impact on performance with high traffic levels. Due to this I usually only set car traffic around 15-20%. In v5 I can set 30-40% with virtually no impact. Or if you want it to look like Portland  (or any major US city on the west coast) in real life, you max it out to 100%.

I did a quick flight last night and I do not believe this was changed. The cars still have the hesitation were all familiar with. I will say however the traffic does NOT have the same impact on FPS as it did in the past. With V5 you can have lots more traffic without impact. I will also say that once you are 1000' AGL the traffic seems much smoother then when sitting next to them on the ground.
