I'm getting stuttering and have worked on several configurations to no avail.  My frame counter is all over the place while at high altitude in the PMDG 737 with very few clouds over water.  Frames vary between 7 and 58 within literally a second or so.  Right now I've got frames locked at 60, I've tried VSync on and off, with and without buffering.  I'm using Adaptive in NVidia control panel.

 

My settings are pretty modest, HDR is off, clouds set to medium, etc.. 

 

I realize this is like looking for a needle in the haystack, but any thoughts would be appreciated!

I would try shifting/renaming the exe.xml and dll.xml files first. It's not unusal that 3rd party programs being called via these files make the sim stutter.

 

In case this cures the situation you can acticate the entries one by one to see what's the culprit.

 

If this doesn't help I would shift/rename the prepar3d.cfg file. If this is the cause it's pretty much the same, you have to identify the entry/entries making the sim stutter.

 

If all this doens't help you have a hard case like hardware issue and may need help by a specialist. I could solve my stuttering issues the way named above, if I had any.

 

Kind regards, Michael

 

 

Hello Chuck, Michael (pmb) knows more about this stuff then i do so i would start with his suggestion.  But just to add, i was getting bad stutters and i finally settled on these settings, these work great for me but as you know every system is different.  I have an i7-3930k 4,1  16 gig  Gtx 980 ti 6 gig Vram

 

Locking my frames at 30/32 with Vsync and triple buffering really done it for me.  I don't use Tweaks or Nivdia Inspector any more

What are your system specs (cpu, gpu, and any overclocking) and what settings to you have for shadows in terms of what as casting and receiving and at what distances. Also, what are you autogen, traffic, and Scenery Complexity settings? 

Perhaps we can come up with some ideas.

I don't want to start another thread on this but I too am suffering severe stutters in the PMDG 737.  My stutters show up only in the VC.  All my outside views are silky smooth?? I am running P3Dv3 at modest settings with VSync On and frames unlimited.  I will have to try experimenting with other settings but any suggestions as to why I get the bad stutters only in the VC would be much appreciated! 

 

My system: i72600k  / AMD Radeon R9 FuryX

Okay, I want to report back to you. After many hours last night and this morning I've found a solution. While I originally suspected one of my add-on's and by eliminating them one by one, I found that wasn't the problem. Next, I checked to see if the networked Avilasoft EFB was the culprit. Not so.

 

I dialed back the MyTraffic Professional aircraft to zero, kept cars at 10% and eliminated the water traffic. Next I set frames at 60 locked and set VSync at 1/2 in the nvidia control panel. All is smooth as silk now with a flight from add-on KFLL to add-on TJSJ with ASN and REX. Plenty of overhead with VAS.

 

Basics of my system: i7-4770k ocd to 4.3, EVGA 780 sc'd, 16g RAM.

 

Please let me know if you need specifics of my settings or system. And thanks for your suggestions.

MyTraffic Professional yeb it causes stutters on my 4790k, 980. What are you going to do about traffic Chuck?

You could try UT2. While it has some performance impact, too (any AI program has), it's definitely less intrusive and stutter-prone than MyTraffic. I made a comparison of all commercial Traffic programs (UT2, MT5, and T360) under an early Prepar3d2 version, and this was the outcome.

 

Downsides of UT2 are (i) it's virtually dead as the developer was lost in space, (ii) as a result of this there will supposedly never any native Prepar3d version, and (iii) there are no up-to-date flight plans available either.

 

This said, you can get it to run under Prepar3d2.5 and Prepar3d3. I use it in both simulators, but installation involves a bit of trial and error. There are severals recipes around how to do it, though, and with a bit of luck you should succed, in case you want to go this way.

 

Kind regards, Michael

Thanks Micheal will pull Ut 2 from the archives file and give it a try..

I also have UT in my archives. I'll probably give it a try at some point but for now I'm leaving well enough alone.

So Chuck it seems MT6 was the culprit for you?  I also have MT6 and will try disabling it to see if solve my stutter woes.  Can anyone direct me to the most straightforward source for guidance on installing UT2 into P3Dv3?

Here I have set MT to 10% ( home base Schiphol ) and I have about the same amount of AI aircraft as before with 30%...

 

I have small jitters when passing several of them standing beside eachother.

No stuttering.

Yes, by trial and error I think MT6 was the problem. But I'm not certain since I also made the change to VSync in the nvidia control panel. I may set MT6 at 1%, see what happens, and then up it from there a flight at a time. I do believe that 10% airline and 10% GA was too much for my system.

I use MT6 on every flight set at 15% and have zero stutters in both 2.5 and V3. 

MT6 alone is not the culprit but too much of ANY AI traffic will affect the system. Recommendations are no more than 15% under normal circumstances.
