TFJ PASI (Sitka) Stutter while moving head...
« on: May 24, 2018, 02:09:35 PM »
Hey guys, first of all I have a brand new fresh install of P3D 4.2 with only my OrbX regions installed. I get *ZERO* stutter or pauses in any of the OrbX regions and/or airports, just the usual slight FPS hit when flying over dense downtown areas like Portland and Seattle (about 26fps with a locked framerate of 33) (all sliders on ultra) My computer is brand new, just built it by copying the system specs off the top of the line Jetline System and saved about a 800$. After a fresh install of Tongass Fjords I installed the "TFX SimObjects AI Update for P3Dv4 V1.1 8-7-17.zip" via the instructions. I have yet to install *ANY* RTMM scenery or other AI addon files. It's just a vanilla TFX install by following the guide over on Avsim. 

Do any of you have an idea what might be causing these pauses when moving my head either inside the cockpit or outside? I am using track IR as my head tracking hardware. Any input would be appreciated as it's kind of annoying. I'm thinking there might be a file or two that is not up to the latest version of P3D v4.2's "standard"? I never saw this issue in P3D v3.4... :/

Welcome, Jocko Flocko!

Hmmm.....The AI changes brought the FS9 based aircraft AI up to FSX level.   All versions of P3D support FSX models so that should not be the problem.   

Here is one thing to check:  TFX introduces a lot of AI into its scenery area.   ORBX is not big on Boat/Ship/Aircraft AI so that is one major change that occurs when you install TFX.   Have you checked to see if the problem persists after you turn the various AI sliders down or to off?

The other thing to keep in mind is that when TFX was built it used many FS9 things that P3Dv4 no longer supports.   Since FSAddon was not able to upgrade TFX with a P3D installer,  there are potential problems with the manual install since TFX was not ever certified to run in P3D let alone P3Dv4.2.   That said, it has been working pretty well for our P3DV4+ users.   

There are still some FS9 models that are being used with TFX but they seem to run okay in P3DV4.X conditions.  However, right now your are a perfect test ground for overhead/issues that TFX might add.  Most of us don't pay attention to stutters now and then, but when you have the system in new form running perfectly smooth with the state of the art ORBX installation, an older piece of software could introduce some anomalies.

Let us know what you discover when adjusting AI settings.

Thank you so much for taking the time to reply to my issue, it's really appreciated.

I thought the exact same thing (AI aircraft, boats, etc) when the pauses started, and these are more like pauses than stutters because my GPU actually throttles back for a few milliseconds, but this is taking place with *ALL* AI traffic turned off... I am wondering if this might have something to do with an incompatible model somewhere in the area.

What I'm planning on doing is one by one moving, or renaming to .OFF, scenery files to see when the issue goes away. This will at least narrow it down to something that can be temporarily disabled or fixed in the future. I really have no idea why this absolutely AMAZING scenery couldn't be brought up to "P3D v4 standards" as there's good money to be made by re-selling it as a P3D version. Without Tongass Fjords there's a massive area not covered by OrbX regions and airports. I would gladly fund a kickstarter.

Anyways, I will keep this thread updated with my findings after my testing sessions.

Thanks again for the reply and suggestions, it was quite helpful.

     It probably couldn't hurt to empty your shader cache folder.   ;)

Do you get stutters when you turn of TrackIR and just pan around using the keyboard or joystick?

     I do.  I can fly around PASI with frames at 28-30 (locked at 30 fps), but when I pan my camera around in a continuous circle, it drops to 2-3 fps.  I am sitting near the PP15 dam project now, on the other side of the ridge from PASI.  I can spin my camera around here with little impact.



Passing over PP16 near Sitka.

Just as Jeff3163 posted above I have the exact same issue if I disable Track IR and pan my head around using the hat control on my yoke. It does the exact same thing, for about 1 second the framerate drops to 3 or 4 FPS while rotating the view in *ANY* camera position either inside the virtual cockpit, spot view or aircraft view (NOT Track IR presets, the default P3D and Aircraft views)

Thanks for heads up Jeff, I've got a chance tonight and I'm going to try and track down the offending file, if I can... The really annoying thing is that even 5 to 10 miles away if I turn my head to look towards PASI (Sitka) I *STILL* get the framerate pause...

     I find it hard to fly while spinning the camera around.   :-[   ::)
     I have grown up with FSX, so stutters were a normal part of flying.  I now fly P3dv4.2, and it is a great improvement over FSX.  But when P3d acts a little like FSX, I just ignore it and carry on.  The rest of the world is beautifully smooth, mostly. 

     I turned off ALL AI traffic, and the symptoms persisted.  So, it may be scenery based.  Maybe the Alaska Power Project? ???  OH ... or sound files ... that has been an issue in the past.   :P
