I get the same thing at 30Hz with locked or unlimited FPS.
You didn't answer my question though... do you get the exact same effect when you pan around at 30-40FPS?

Yes I do. Exactly the same. I cannot discern one frame from the next at 60fps so long as I pan at a slow to moderate speed. At 30fps I can discern the "leap" from one frame to the next. It a jittery movement rather then a smooth movement. It's not the stutters you normally hear about in FS. They are caused by long frames among other things i.e. when frames as not rendered on time. This effect is cause by all the frames being to long but they are all 1/30th of a second so when you are flying straight and level everything looks perfectly smooth because subsequent frames are very similiar. It's just as smooth as 60fps but once you start panning around subsequent frames a very different. Check out this website which demonstrates the effect very well: AS I said before Flight sim for now is about compromise and personal preference.

I don't expect 60 FPS fluidity at 30 FPS. I know the theory you're talking about. I know all about ghosting and motion blur. But what I'm experiencing is much more pronounced and annoying than what is to be expected. If you look at the clip in fullscreen is pretty much what I see on my monitor. I hope you didn't watch the clip on tablet or mobile phone because the effect wouldn't be as obvious as on the big monitor.
If everybody experiences exactly what it is in the clip at 30-40 FPS, than I'm seriously confused about a couple of things...
Why are people trying to help me if they experience the exact same thing? Why is 30Hz all the rage nowadays if the end result is exactly what it can be seen in the clip? It looks crap and it hurts the eyes. |

I did watch it in full screen on a 24". I will concede it appears that the effect looks worse in your video than it does in mine. I recorded this at 1080p 60fps and 50mbps. It looks accurate to me on youtube. The monitor was set to 1080p at 30hz and in P3D setting Frame rate is unlimited and Vsync is on. |

I have updated the 2 videos in my post above. They are now 1080p (still might show compression artifacts
 ). 30 FPS is definitely acceptable on my system. @0Artur0, as I mentioned previously, are you sure your looking at 30 FPS? It really doesn't look like it. Could something be limiting the frames? Can you (or did you) try an external frame counter?

Long time since I've been here but in this post it looks like everybody overlooks one thing, your LG monitor does have a response time from 14milliseconds and that is your problem, for the flightsim you need a monitor with a response time of max 5 milliseconds and even better with 2 or 1 millisecond, everybody, including me, has this problem but way less then you have and not disturbing at all, my monitor has a response time from 2 milliseconds.
Hope this answer is of any use. Herman

Once I saw that the issue in the OP's video was worse than mine. It crossed my mind that it had something to do with his specific display and I am sure you are right. But I did notice that on my system and display it appears that its worse in Xp11 than it is in P3D V4.5. But it doesn't bother me in either.

Herman, I'm the one with the LG monitor(s) not the OP.  But the response time is 5ms and I don't see the effect to this extent at 30 fps. However I usually run on my secondary monitor (LG E2360V-PNW) which is set to 30 Hz. Randy

He already tried replacing the monitor, but not sure what models he has tried. However, it's not ghosting he's seeing. Randy

Fair enough. It sure looks like ghosting but more like 24hz than 30hz. Anyway good luck with it. I hope you get to the bottom of it. Nothing worse than being bogged down with FS problem and not being able to fix it.

Agreed. I'll be interested in what fixes it for the OP, in the end.

Ok so this is something other see too, not just the OP?
I can't advise past basics because I do not use TrackIR. I don't believe any BIOS change is going to make a difference. Seems to me to be a direct hardware-device/software in use issue

As I already said a couple of times, I uninstalled TrackIR and ChasePlane and the effect is still there so it has nothing to do with either of those. Yes, a few others are also having this issue. I guess I'll just have to get used to it and fly in less FPS intensive areas. I tried absolutely everything except reinstall Windows 10. Maybe I'll do that when new version of P3D is released.

Ok, I misunderstood.. I was thinking uninstalled/reinstalled and not just completely removed/tested.
That is very strange then if the issue is present without the addons. It almost reads as if there is something loading while panning that is causing the problem. I do know the camera.cfg entries I posted on page 1 of the thread do speed up/smooth out panning by raising the speed however if the system is under a load and frames are dropping I can see how that could create a jitter or jump in the visual pan.

I might have a fix for you! I think its going to depend on your display though. OK: 1. Set your display to 24hz in Nvidia control panel. 2. Load setting that will get you at least 30fps with vsync off and Frame rate set to unlimited. 3. Set your Frame rate limit to 25 with Vsync on and Triple Buffer off. Go fly. If you get the same results as I did, you'll know right away.

I noticed this same effect once I pan around the screen would like blink on my new build using a LG 43UD79-B @ 30Hz, my in game settings @ 30Hz but when I ran at unlimited I didn't notices any issues. I'm thinking it may be my settings are aggressive I'll play around with it and see. Build consist of the following:
i9-9900k stock G Skill 3200 2X8 16GB CL14 EVGA RTX 2080 Ti |

Having just gone back to P3D albeit v5, I saw this and can tell you that this is normal unless you are way above 60 fps. When I'm in the PMDG 747 my FPS is around 40 to 46 and CPU often maxed out... although I lock it at 30. My Chaseplane view is like this... but when I switch everything off and shut down the cockpit completely it becomes extremely silky smooth. The CPU is barely 15 to 20 percent at that point. So what is happening is the sim takes priority of your resources and Chaseplane is always playing catch up. Put this here, now, in an old thread for anyone else's benefit. P3D is far from dead !
