How to Cure VC Stuttering in the PMDG 777?

[MrYorkiesWorld 3]

Hi guys,

So I'm wondering if someone can help me with this as it's rather frustrating with my PC which is more than capable of running P3D on medium to high settings.

The FPS inside the cockpit of the PMDG 777 is around 35-40 FPS which is great, however when it comes to panning around with the camera it seems very "jerky" and stuttery which puts me off completely.

It doesn't happen all the time, but mainly whilst on the ground.

The only tweak for my P3D cfg that has helped so far is Fiber Frame Time Fraction 0.01.

I have tried locking the FPS at 30 which makes the issue a thousand times worse, and only locking at 60 or unlimited makes it slightly better. I've tried enabling and disabling vsync and triple buffering which has very little (if any) effect. I have also tried enabling/disabling vsync, triple buffering, Hyperthreading and Intel Speedstep, all of which make very little (if any) difference at all...

How can I get rid of this annoying stutter and get smooth panning inside the cockpit? 

The problem is completely gone when panning around outside the aircraft.

Specs:

Intel Core i7 4790k overclocked to 4.4GhZ
NVIDIA GeForce GTX 980
16GB Corsair Vengeance RAM
Windows 10 pro 64 bit

 

Addons:

 

Active Sky Next

GSX Ground Services

PMDG 777-200 (Base Pack)

FTX Global

REX 4 with Soft Clouds

Any suggestions would be great guys!

People need to stop tweaking their P3D cfg file. Delete it, let it rebuild, put the settings where you want them. The FFTF tweak is a tricky one to work with. See how P3D handles without it. Can you also please put screenshots of your settings? That'll give us an idea if something in your settings is causing stuttering. Another thing: What hard drive do you have?

Are you using EZDOK for camera positions ?

 

If yes -  remember to disable the hatswitch inside P3Ds controls and only assign it in EZDOK software.

If you are using a 60hz panel, that would explain the jerky/stutter behaviour, especially in the VC getting 35-40fps, outside view you are likely around the 60mark.

 

as a test try reducing sliders until you can get 60fps in vc - turn off weather/ai, go to a light airport etc and try your horizontal panning,

 

if you can get over 60 in the vc then turn on v-sync & triple buffer & test again.

 

good luck

People need to stop assume that other people are over-tweaking just because they happen to mention a tweak. He said that FFTP is the only tweak that helps and from his description I think its safe to assue he has experiene in this area.

 

Back to the issue... 

I've never tried the PMDG 777 but if its anything like the NGX I can say that me and others have had this issue for years.

FPS is high, GPU and CPU is nowhere near max, yet the stuttering is sometimes extreme.

At least in case of the NGX its because of some panels, mostly the PFD.

It can be reproduced for example by using 2d view and then add/remove a single panel att the time and check the difference.

 

The only solution I've found is to disable the f/o panels (when using VC), and to set the FPS for all panels to some extremely low value like 2 (works for 2d and VC). In the NGX this is done in the FMC under performance options.

what programs do you have running in the background? Maybe your HDD is doing something that is causing your fps to drop. Just a thought.

I was having the same problem, one of my installs must have tampered with my P3d cfg file, I deleted the cfg file and let p3d rebuild it and all was good after that.

Did you turn down the FPS refresh in the FMC like I suggested?  as it seems to be a VC problem.

Philip LaBianca,    I just wanted to say thanks about the P3D CFG file. When I first installed  P3D I never touched the CFG file and it had no issues. I then installed several add-ons and took the suggestions by many Simmers opinions to better the Sim.. Well, After several tweaks it got so bad  I didn't know how to fix it. I almost uninstalled and reinstalled P3D. After reading your reply I never thought of just removing the CFG. Well I did and all the stuttering problems are gone. Thank you for your Help.

How you do it?
