@iceman06 Without having looked at your log yet (which I will do as soon as possible), you are using MSI Afterburner, which is known to be a performance issue on its own. Can you please reconfirm that the issue is still happening, if AB is uninstalled?

 

EDIT: sorry, just saw that you tested without already-

I am at work rn, will report back later.

In the meantime, please create a FIXED pagefile on your FASTEST NVMe SSD of at least 32 GB in size and retry.

 

I don't use MSI After. from the same reason for about 6 months now. It caused a lot of stutter or even picture freezes.

Radar altimiter has nothing to do with stuttering, at least I didn't find any, if its not Afterburner, it's got to be something else.

@Special K Thank you for posting your help here, I will answer you step by step. 

 

-First point ; Msi AB, I only use it when I want to analyze certain data, I haven't uninstalled it but it is programmed to activate only when I ask it rather than at session startup by default. Can uninstalling it make a difference when it is not active in my tasks?

-Second point; the pagefiles. Indeed, having tested a few manipulations recently, this one was by default when the last Dcs.log was sent, you will be able to see that I have now 
set it to 32GB, unfortunately I don't see any difference.

-Third point; Regarding the BIOS update. After trying a few updates a few years ago, 
I decided to go back to the original 0707 version since the later versions exerted abnormally high voltages and caused temperatures that I found unnecessarily high without any benefit. 
The only problem is that this version restricts me since it doesn't allow me to use ReziseBar, which is why I wanted to try version 1003, 
which is also old but one of the most stable according to Asus users.
Do you think the Rezisebar is an advantage in DCS? No one has really been able to tell me if the game supports it.

-Fourth point: The armory crates and DtsApo programs. Armourycrate is a real pain in the neck. Unfortunately is useful for my Rog Spatha mouse profile and all my LED lighting, which is the only reason it's there, DTS  has been disabled. I've determined the circumstances of these application crashes, and they only occur when closing sessions when I turn off my computer. No problem,so I even disabled them at startup for a test, and it makes no difference to my Viper problem in DCS.

-Concerning Windows 11, a touchy subject but on which I know that I will have no choice but to end up giving in, I also know that the clean and complete
 reinstallation of my PC will take time, which is why I want to do this calmly when time allows me.

 

-Final points;

Hotplug is already disabled, SSAO or any other settings make no difference to my problem, I've tried everything possible on that side I think.

Fxo / Metashaders 2 cleaned several times with nvidia shaderds cache and direct x as well

DCS repair/uninstallation/reinstallation performed with no effect either.
I don't have this file in saved game Scrips\Export.lua 

 

This problem is quite frustrating and occurs when my alt radar is activated only unfortunately I do not understand how this is possible but it is nevertheless linked to my problem on my PC.. unfortunately you have to see it to believe it, What is even more frustrating is to see that no one can reproduce this on their configuration, making my problem even less solvable. 

I'm attaching another DCS.log as well as a DXdiag again.. ignore the DTS crashes they are not problems at all.

No particular reason to think this will solve your issue, but currently you are one version behind on your DCS, so worth updating and seeing if it helps.

I have no trouble believing that you are not suffering from the same problem as me since in fact until now no one has been able to reproduce these stutters. To state with certainty that this has no connection with radar alt when you cannot reproduce the problem is quickly said... the real question would rather be to know why I no longer have the stutter when I switch to OFF or STBY?

Aucune raison particulière de penser que cela résoudra votre problème, mais actuellement vous êtes en retard sur votre DCS, donc il vaut la peine d'être mis à jour et de voir si ça aide.

You're right, I'm going to update it. Unfortunately, it's been a few updates that I'm thinking "maybe" my problem will be solved... but nope! 

I just hope it doesn't add another problem!

I must say that I made my DCS forum profile just to coment here about this issue and I have the same exact problem with F16 as you have for god knows how long. And I dont know how ED can’t reproduce it.

 

It happens to me while I play on my flat scren monitor on 75fps cap, or 140 cap it doesnt matter. Doesn’t matter the settings I put or whatever in game it is always the same stutter result when I roll the plane and it is always while rolling aggressively or suddenly. It doesn’t happen while flying straight.
 

I am glad that I found this topic here and as soon as I turned off radar altimeter the heavy stutter that annoyed me for a long time was gone instantly.

I thought my pc was the problem but even though I upgraded to ryzen 7 5700X3D and 64gb ram with my rtx 3080ti. It still was happening. And at that point I became suspicious that maybe it wasn’t my rig after all.
 

No other module of mine has a stutter of any sort except my F16 which is also my most flown module. To the point I thought it was the most hardware intensive module since my Phantom flies perfectly and smoothly both on flat screen and VR.

I must thank Iceman06 for figuring out it was radar altimeter. So now I strictly fly F16 with radar alt turned off and I have no issues whatsoever VR or flat screen. Finaly I can roll the F16 without a very nasty stutter at least!  
 

I really don’t know what the problem could be at this point but hopefully it can be solved. I am just surprised not many people share the same experience and even more suprised that ED cannot reproduce it?

The 1st part of that sentence explains why ED can't reproduce it.  Computers and programs are complex.  It's likely some rare combination of software/hardware that the people having the issue have in common that causes it due to some weird and equally rare interaction with DCS.  Even within DCS itself seemingly unrelated things can interact (i.e. a plane mod causing the supercarrier to not appear in game), so not surprising that external things could also interact badly.

Hello @Astralox65 !

Welcome to the forum, I'm not happy about your problem but being able to read (finally) about someone who suffers from the same problem as me makes me feel less alone !

Solving a problem that few people are able to reproduce on their machine is extremely difficult
as you can see, it would be interesting to know the complete configuration of your PC, perhaps we can find some similarities here, logs files, dxdiag and
also software, a driver in common that could perhaps be problematic for us.

Another hypothesis is that few people were probably able to establish the link with the radar altimeter or even notice the stutters (most people I know are not bothered by stutters, their eyes does not even notice them).

Aside from that, the question of why ED isn't able to reproduce the problem is that all machines are different and more or less sensitive to certain things.
In any case, I'm glad you came here to say that you've noticed the same thing, and I invite those who can to also contribute their piece of the building, as it will be of great help ! 

Don't hesitate to contact me even by PM if you wish, I will answer you as soon as possible!

Only because you see the same result does not necessarily mean you have the same root cause.
Can you please provide the following:
- a recent dcs.log from a gameplay where you had the issue
- a dxdiag.txt which you can create by running a Windows tool named dxdiag and press save everything at the bottom.

Not sure if I have asked that yet, but you do not start your DCS as admin by chance? If yes, don't do that please.

For rebar, yes your DCS will most likely benefit from it. I am not a big fan of staying behind on BIOS updates, as the changes they made usually are fixes to issues they encountered. If they upped some voltage, they probably did that to stabilize something, most likely memory (e.g. better 4 stick support) or the like.

Ce n'est que parce que vous voyez le même résultat que cela ne signifie pas nécessairement que vous avez la même cause profonde.
Veuillez fournir ce qui suit:
- un récent dcs.log à partir d'un gameplay où vous avez eu le problème
- un dxdiag.txt que vous pouvez créer en exécutant un outil Windows nommé dxdiag et appuyer sur sauvegarder tout en bas.

Je ne sais pas si j'ai encore demandé ça, mais vous ne commencez pas votre DCS en tant qu'administrateur par hasard ? Si oui, ne faites pas ça s'il vous plaît.

Pour les barres d'armature, oui, votre DCS en bénéficiera très probablement. Je ne suis pas un grand fan de rester sur les mises à jour du BIOS, car les changements qu'ils ont apportés sont généralement des solutions aux problèmes qu'ils ont rencontrés. S'ils augmentaient une certaine tension, ils l'ont probablement fait pour stabiliser quelque chose, la mémoire très probable (par exemple, un support de 4 bâtons meilleur) ou similaire.

 

I spoke with Astralox65, and our problem seems to be similar. Obviously, a track under the same conditions, on the same card, would be the best way to confirm this.

I'm not running my DCS as administrator; I've done so in the past, and it crashed immediately upon startup, as far as I remember.

Indeed, you're referring to the BIOS update, which caused high voltages with my XMP profile, causing the VCCI and SA to rise to around 1.47 volts, one of the reasons for my rollback.

I admit that updates can be a major improvement in some cases but when it comes to the bios some bad experiences lead me to think that if it ain't broke don't fix it, sometimes it can do more harm than good so I remain hesitant when it comes to taking the risk.

My PC is performing quite well with fairly respectable performance despite its age, my games work well, the Viper is the only one that really causes me a problem.

However, I will still try to see if the 1003 update and the activation of Resizebar offer a solution to my problem. If my tensions increase, I will take the time this time to define them manually without excess.

Thanks a lot for the input, it seems like it helped a lot to turn on rebar in BIOS, and turn off overlay in GeForce Experience.

 

Also, I had DCS run by an administrator, and I reverted that back to standard. 

 

And now I am stutter-free completely.

 

But I must say I am still testing, so I will be back to confirm that stutter with F16 is indeed gone fully. I only did a couple of isolated missions for now, and it all went good.

 

I will be back with more info, and hopefully, this is a user error, as I suspect it to be. I and Iceman06 have a very similar PC configuration, GPUs are the same, similar 240hz 27-inch gsync monitors with 64 GB ra,m etc... CPUs are different, only
