Stutters on final. It's getting annoying.

Recommended Posts

I have p3d verision 3.3.5 And on final in the pmdg 737 I getting stutters. It's very annoying.

What causes the stutters?

I installed p3d v3.3.5 for a few weeks ago and not a ploblem at all but suddenly I have stutters on final.

I am in the middle of diagnosing/documenting constant serious stutters in my Lancair v2 on the KLAX Rws 25R and left approach...even on the roll out....you can imagine how pi55ed I am having just installed a new GTX 1080/I-7 6700k this past weekend.

 

P3d and other scenery on SSDs, Upgraded Client and to 3.3.5, Unchecked FTX SCA, UTXUSA V2 in scenery and set all sliders to default...still there.

 

Reallllllly freeeking frustrating...

What Vsync + frame rate limit do you have set in P3D.

I'm only avoiding the stutters by using Vsync ON and Unlimited or 60 frames, set in the sim.

I have not installed any addon scenery yet though.

I have Vsync ON in p3d and in nvidia controlpanel I have it set to half refresh rate. Fps set to 32. Now I get Micro stutters only sometimes.

Try deleting your Shaders folder,  You never know 

 

► Computer ► Local Disk (C:) ► Users ► you► AppData ► Local ► Lockheed Martin ► Prepar3D ► Shaders

 

=================

 

For beginners.....

 

It is recommended to delete your Shaders folder any time you change your Graphics card, update your Graphics driver or Harware, Make Graphic changes to your Sim or you install a new program or Ad On into Prepar3D.  The next time you start Prepar3D, your Shaders will Rebuild

In Lancair v2 / dual GTN750s

VSync is Off

FPS set to 31, although FPS around KLAX is way slower...more like sub-low twenties, so the efficacy of setting it higher is dubious.

 

I will give it a try.

 

Thanks,

Chas, I get the same thing at KLAX and FTX SCA.  I thought it was the amount of autogen in LA area but if you still have it when FTX is not applied then there is something else causing it.

what does 12FPS, 21%CPU Utilization and 19% GPU Utilization this tell y'all???....at first blush, methingks something is rotten in Denmark...

 

with UTXv2, smooth as butter then Litterally a 1/2 second HALT...then smooth again...I've got video on that...unchecking UTX and activating FTX-SCA is what you see here...Vsync OFF, 31FPS limited in P3d Client /Content v3.3.5.17625,

Oddly, P3d itself shows V3.1.2.15831...do I have a problem here?

 

Advise anyone?...shameful performance NOT Stressing CPU/GPU beyond 21% utilization...#####???

 

Regards, and thanks in advance for someone who knows what Ive done wrong responding,

I agree whole heartedly. As my installation has evolved I've lost count of the number of times I have deleted this folder and allowed the sim to rebuild. Does no harm whatsoever. Just remember, and it's been said umpteen times, DO NOT delete the ShadersHLSL folder in P3D root otherwise you will find yourself up the proverbial creek without a paddle......unless, of course, you have remembered to create that backup before launching yourself into the unknown..lol

 

Also, while you are at it, I suggest you check the content of your SceneryIndexes folder. You will find it in the same folder as Scenery.cfg. Corruption of the numbering sequence can and does occur, I know, it's happened to me twice and I still haven't identified the culprit. The indexes should be in an orderly sequence to match the content of your Scenery.cfg. If you see any deviations then simply delete the entire content of that folder (SceneryIndexes) and P3D will rebuild at next run.

Better yet, just quit nicotine altogether. I did it 40 years ago from 3 packs a day.

Go easy. The shaders folder only need be deleted if code in the HLSL folder changes.

 

It's possible that some functionality surfaces or changes with the GPU, so the programmer adds it into the sim and makes changes to code in the HLSL to incorporate aspects of it. OK so then you get guys saying the shaders needed deleting because of a driver update, but it was because of code changes in the HLSL folder.

 

The shaders from nothing take over two minutes to build and gives your sim the stutters during that time depends on hardware and disk speeds. But it doesn't end there because quite often there's more shaders to be built as the user progresses around different parts of scenery.

 

When we get a P3D update and it includes HLSL files in the zip, then we need to delete the shaders, so that the sim builds them with the new code changes. Otherwise we do not need to since Shaders can take months to accumulate depending on the areas visited during flights.

Oh, I'm relieved.  :wink:   As it happens, I'm not a smoker, but that's good advice for those who still do.  It's really such a 20th-century thing.

Depends on what you mean  - the comment was about smoking.  Clearly, most of us were born in the 20th century.  But that misses the point.

 

Some are mired in 20th century societal and cultural attitudes, and don't embrace the technology we now enjoy.  Some of us are not.  YMMV.

What Vsync schould I have. Vsync ON or off in p3d. Vsync in nvidia inspector? Nvidia controlpanel. For best smoothness

Share this post

With the slider set to Unlimited fps, VSync On in P3D Display Settings steers your GPU to output at the refresh frequency of your monitor. Whereas leaving VSync off allows the GPU to make frames at whatever rate it can. Combining Triple Buffer with VSync can increase the smoothness but also increases the load on the sim. Setting the fps slider below Unlimited fixes the period between frames with a look-ahead buffer, it is not a Limiter and increases the load on the sim. With NI we can set an fps Limit that appears to P3D as if it is the monitor refresh.

 

What works best depends on your monitor and setup. You might find that increasing the AA or Clouds or Shadows slows down the sim a bit and produces a more consistent fps without any limit or Fixed framerate.

 

Because P3D operates in a desktop window it can look like stutter when the frame period does not match exactly with the monitor refresh or a division of it. You may find Fixing or Limiting to 30fps and using a monitor with 120Hz refresh performs better than a monitor with 60 or 30 Hz refresh.

I use unlimited fps with vsync and tripple buffering on a 30 HZ 4K. Very very smooth as long as it stays around 28-30fps.

 

I must admit that having vsync off provides more stutter than i used to have with my 1920X1200@60 hz. Not sure why. Maybe because it is 4K.

 

But try it out.

I will test KLAX FSDT with Legacy v2

So i did a test Chas, something is wrong with your setup,

 

Tried with OpenLCNA with and without Vector and smooth 26-30 fps all along FSDT KLAX 25R and around.

 

If it goes below 27 i do see some small stutter but on 95% and on rwy 25R 30 fps butter smooth ride.

 

FTX SCA is another story 15-20fps

 

Actually i could not see any differents in the test with or without Vector which is strange as for instance KORD Chicago areas is taking a big FPS hit with Vector (all option on)
