P3D v4 stutters after ~3-4 hours of flight

[Harvgordon 54]

Dxtory is making problems for me in V3. You can use MSI Afterburner + RivaTuner instead.

I've been getting stutters as well....I lockl my frames at 30 which it very stable, however, I get a lot of stutters. I am running ChasePlane with the PMDG 777. VSYNC & Triple Buffer is turned on. Could PTA cause any of this? Closing AS16 did not change anything. When I got to the spotview outside I get no stutters.

Also when I set FPS unlimited it seems to be better. I would rather keep it locked at 30, no?

 

Thanks!

I stopped and restarted AS16 and that did seemed to help the stutters.  Very annoying on landing to have them when smooth on take off and most of the flight.  I stopped ASCA and used Pr3d v4 clouds and that seemed to help a bit.  Will keep testing.  Anyone else find this helps?

Thanks

Does everybody who gets the stutters after a few hours use the Navigraph Simlink beta? People seem to be reporting that could be the cause over at the Navigraph forums: https://www.navigraph.com/forum/viewtopic.php?f=93&t=4654&sid=fa1ea985f39de19ef65b50979e176798 (registration required). 

I have it too and hadn't thought to look there, but I do track my flights with it since it was released. Will try it on my next flight.

Good find!  I am indeed using SimLink with the new Desktop Charts beta.  Will uninstall and try another long haul to see if I can reproduce.

Doesn't look like I'm using it :(

I double checked it in remove programs and I don't see Simlink.

Interesting, I have simlink running and get stutters after a long flight.

Not rating simlink very highly, as it is always dropping out and saying it can't connect. I will uninstall it for now.

I will try a transatlantic flight without it, maybe UK2000 EGCC to FSDT KJFK.

 

May be a couple or three days to get time to do it though.

I did a return run from the flight that caused the stutters last time.  This time around I removed SimLink prior to firing up the sim.  Had the aircraft sit on the tarmac at Fort-de-France (FDF) for about 2 1/2 hours prior to departure, planned my flight, programmed everything, took off and went to bed.  I woke up this morning at cruise about an hour prior to ToD for Paris Orly (ORY) and guess what?  No stutters!

I will do further tests to confirm but so far it looks like it was indeed SimLink causing the issue for me.

iam oldschool run W7, no problem with stutters (no simlink) did a 18hour total flightime in 777 no reload of the sim.

4K 49inch Samsung , vsync on and triplebuffering , Ansi x16, 4xssaa

I completed this flight last night and I'm pleased to say no stutters without simlink.

Happy days, well chuffed I am.

I saw the post on the Navigraph forums, and although I am using Desktop Charts, I didn't run the SimLink.exe that permits you to track your flight on their moving map.  So, I didn't think that could have been causing my stutters.  But, several pointed out that the Add-on.cfg file [in the \\...AppData\Roaming\Lockheed Martin\Prepar3D v4 folder] causes the Simlink.dll to startup with the sim, so the .dll was indeed running.  I disabled Simlink.dll in the Add-on.cfg file [changed the ACTIVE switch to "false"] and my stutters appear to be history!

I'm thrilled this was discovered.  No doubt Navigraph will get that solved before their final release.

I'll have to check but I uninstalled Desktop Charts....Shouldn't that uninstall the .dll? Or would I still need to remove it manually?

Almost certainly that would have removed the .dll file.  Just check the Add-ons.cfg file to see if it is still there.  You should be fine.

I'll check later today. I already uninstalled Desktop Charts and I'm still getting stutters....Will report back.

And this is after a multiple of hours, not right from the start, correct? Because as far as I know everybody has this after a few hours.
