Good morning/afternoon, everyone!

I have had this issue for so many months, through every reinstall of P3D v5 and Windows 10. The my specs are as follows:

---

CPU: i9 9900K @5.0 GHZ Hyperthreading Enabled (Happens when disabled too, just not as much).

GPU: EVGA GTX 1080Ti FTW3

Motherboard: ASUS ROG Maximus XI Z390

RAM: 16GB 3600MHZ

P3D is on an M.2 SSD, OS on one as well.

Latest update of 2004 Windows 10.

---

I am on the latest hotfix of P3D, and I have a video of the issue and my settings down below:

I've been dealing with this "FPS variation" issue for so many months now, and it seems that not everyone with a 9900K has this issue. I would really appreciate it if I could get some assistance with this problem.

Thanks!

EDIT: It seems to occur REALLY badly on takeoff, the FPS just plummets... and YES, before anyone asks, this happens on v4 as well.

I had to add something.

  Gee, this sounds a lot like another flight sim out there - I think it's new - but the name escapes me right now🤨

Gee, it sounds like this is the P3D forum, and I'm trying to fix a problem with P3D. Does MSFS have the FSLabs A320? Nope. Does MSFS have ANYTHING PMDG? Nope.

So go take your MSFS comments outa here. Maybe to... oh.. I DON'T KNOW... THE MSFS FORUM???

I have the same Processor and i warmly suggest to do the following:

1. disable HT via the BIOS. There is a difference especially with the overclocked CPU. With HT off, all physical cores are running on 5 gig´s. This isn´t the case with HT on where the overclocking is limited to the first physical core and spreaded for the others includign the virtual cores.

2. limit the FPS via the NVIDIA settings to 30 FPS and set you Monitor to 60 Hz. Leave the settings in P3D as they are. 

P.S. forget about any afinity masks. That´s all placebo. Let P3D engine handle the tasks on the processor itself. V5 is already very good in doing this.

Also consider that even with our 9900k won´t mean we will get rid of stutters or "hickups" like longframes completely under all circumsatnces. But mine is running smooth as silk generally and we have similar settings. The smoothness counts for me mainly, that there is no stutter while taxi or takeoff, nor whilst in flight. This is where my P3D is allready very smooth. But i get sometimes one longframe especially on approach. But this can come from AktiveSky or other add-ons or even from SimConnect at that point.

I can remember that the effect of this regular "delay" i have noticed in your video, like 1, 2,3, 4, fiiiiiiiiive, 1, 2, 3, 4, fiiiiiive.....happened to me after the WIN10 update and the last NVIDIA driver when the GPU throttling was implemented. But with those changes above it´s gone for me.

Thank you, this is exactly the answer I was looking for. I appreciate your help.

Well written.

CPUs with many cores behave better with HT disabled. People with 4 core CPUs are better off with HT enabled.

Regarding the monitors refreshrate you’ll have to try what works for you. With 4K displays you might be better off with 30 hertz.

Here and there a long frame is normal. Sometimes lots of objects are loaded in 1 batch or weather is injected at that moment.

This is good advice thanks. I tried this and have had some small Fps / smooth increase. 

On another note, something that has annoyed me for a long time is when I change to outside view half the aircraft is black for a mili-second, and its become a habit of annoyance for me ....lol

This happens, when the fairly huge textures data are loaded into the RAM/VRAM. Because it´s not only the flat picture of a texture. Also the data which are embeded in those textures needs to be transfered, like bumpmap, PBR, vectoring-data and many other stuff i. ex. 

I can notice in flight some longer frames especially when many clouds on many levels are displayed. Because i´am using unlimited settings for AktiveSky and ASCA in conjunction with ENVTEX for cloudlayers, -coverage and -drawdistance, of course it´s sometimes noticable when all the different cloudtextures are loading. But that´s half of a second and only from time to time.

But when i put into account, how much Megabyte, or even Gigabyte of those data are flushing thruh all those small pipelines on the motherboard, from the SSD, thruh the processor into the RAM/VRAM every milisecond, i´am fairly satisfied of the overall smoothness which is clearly noticable compared to V4.5 fro me.

I have much the same setup, although I haven't tweaked Active Sky or Envetex/Envshade from stock settings. I'm very happy with the changes I made after your recommendations.

I always test out on FSLabs A320 EHAM to EGLL, I'm a glutton for punishment re fps, but with most settings high I was running stable at 30fps dropping to around 24 fps, and had a noticeably smoother flight, even above the West End in London, never had it that smooth before. 😃

indeed, one major suggestion is: 

If you are concerned about the FPS which shown in the screencounter, first thing you should do is, to switch it off and forget about it.😜

We all know the effect that a small wound becomes even more painfull at that moment when you take awareness of it...

Haha yes very true, yes I knowwwwwwwwwwww, but.......... but curiosity killed the cat!

In all seriousness I think I will turn the fps counter off.....at least try 😺

To be quite honest, I don't know what you are complaining about.

Stop making yourself and me giddy by moving your veiw so quickly. Do you do that all the time?

If so, it is no wonder that you have not realised that your sim is running extremely smoothly.

 

The best thing LM can do is take a leaf out of MSFS book and remove SHIFT Z ban it, tweak for smooth flying not for fps.

PS locked at 30 so SHIFT Z pointless i already know.
