@Ray Proudfoot, Looks like same build as @vonmar

P3D5.4.9.28482
Sim Connect: 5.4.0.0

Windows 11 updated today as well
Version: 25H2
Build: 26200.7309
Windows Feature Experience Pack: 1000.26100.275.0

CP Always on top not checked

Just did a short flight and works as normal. Not sure what changed. It tested it after I updated to 25H2 back in October and it wasn't working then and had been on a hiatus ever since until the other day. I will report back with any changes or if it start having issues again.

P.S. Do you have a TrackIR sensor? I did remember disconnected mine but doubt that was it but maybe worth a try if you do have one.

@gaumond, I'm on 25H2 and just updated to 26200.7309.

Started P3D via SimStarter which loads all required executables including ChasePlane.

Without touching the CP options I panned inside and outside the aircraft and the smoothness was there. 👍

Let's see if it's fixed with further tests but it's encouraging.

No TrackIR sensor here.

 

 

Second test with a different aircraft and this time I left it running for around 20 mins C&D on the apron. No issues.

Microsoft messed it up and it looks like they’ve fixed it. Whether that was knowingly who knows? 😁

I tested again just now (still using newest WIN11 update).

On my 2 monitor setup I still have the Chaseplane problem (slow panning) if:

Always on top is selected then Minimize Chaseplane Interface to the taskbar.

Slow panning.

Next:
Maximize CP to the main monitor or the 2nd monitor and I get normal (fast) panning.

Next:
Minimize Chaseplane Interface to the taskbar.
Slow panning.

 

Edit:

Same with P3D 4.5.14.34698

added info

@vonmar That was my experience before it "fixed" itself. I always had to leave it open on the second monitor as a work around. 

Couple other thoughts, Do you have any optional .net updates available? I also updated my graphics drivers to the newest NVidia driver with the optional hotfix (581.94). It had a lot of performance improvements in the gaming fps department so could be worth a try and see if those help because we pretty much have the same versions so far.

I installed it.

Still have problems.

 

You are perhaps missing one thing.

I know Ray has Windows 11 Professional.

My setup is Win11 Home. 26H2. 26100.7309. The latest offered for me on the update page.

No change this morning, still had to do the On/off trick with Chase plane. Otherwise, pans but slowly.

So maybe it is windows version based?

I use 2 monitors in Windowed mode.
I have Chaseplane in P3D4, P3D5 and P3D6 Personal 6.1.11.

WIN11 Home updated on 12-2-2025
Build 26200.7309
Feature pack 1000.26100.275.0 

Just to verify if your Build is 26100 or 26200?

Notes:
P3D6 Personal looks to be working properly (limited testing). 

For P3D4 and 5:
I get different results depending on Chaseplane Options (Off or On):
Default to Always on top
and
Minimize to taskbar

 

 

Mine is 26100. It insists this is the latest (for me at any rate). Windows updated this morning.

Well after working perfectly on Wednesday I had a quick flight today and frustratingly the panning was back to substandard. I had to toggle the option on/off to restore smooth panning.

It’s a slight nuisance, nothing more.

Thanks for retesting and confirming the original problem has returned.

I see Chaseplane problems with P3D4, P3D5 and MSFS2020.

P3D6.1 is looking good but limited testing.

Edit:

Chaseplane and FSX (Steam) on a 2nd two monitor PC with WIN11 also looking gods

For me, it never went away.

I just apply the fix each time.

Apologies for resurrecting this one - after a very long absence I have recently (upon acquiring a slightly more capable GPU) booted up my sim once again to do some more Concorde flying. At present everything seems to have been preserved in good working order with the exception of Chaseplane (though frankly I was expecting Win11 to break at least something given how poor of an OS it is).

The minmise to taskbar trick does work for me - albeit I have to reapply it each time  I change focus to a new window which makes using anything outside of P3D itself (navigraph charts, PDFs etc.) somewhat irksome. I am assuming (barring disabling the offending Windows updates) that this will have to become standard procedure, unless anyone knows any tricks to have the fix work for the entire flight?

@SimeonWilbury, that is very frustrating. I run a second PC which shows maps etc so I don't really shift the focus away from P3D.

Any supporting software such as LittleNavmap uses very few resources. Have you considered using a second PC with a separate monitor of course? WideClient is needed to fool software into thinking it's running on the P3D computer.

I moved my previous computer over to these tasks as it enables me to extend its life. Drastic I appreciate but it does bring other benefits.

That isn't something I had previously considered but is something I might look at potentially - I do have a win10 laptop lying around that would be able to run charts etc. no problem. Or perhaps I could pick up a tablet to use as a form of EFB...

As I'm only on my first flight currently, my initial thought is to do a few more to see if I can put up with the reduced QOL - if I put chaseplane in the corner of my second monitor I can manage (mostly) normal ops at the moment it seems, so it might be that after doing it enough times I will 'adapt' enough for it to be less annoying (even a clunky workaround is better than no workaround I guess).

In an ideal world we would get a hotfix but as it seems that isn't going to happen it may just be another "legacy software" quirk to put up with.
