Hi.

This start to point out to the motherboard and the BIOS version. I should try to update my BIOS first...

Saludos.

That may help for some specific Ryzens (and generally won't hurt on any other system), but I don't believe the bios is a major player in this issue.

Folks,

just for the lol'z, can you try the following:

a) set maxfps to exactly 120 and/or (unrelated)

b) set preload radius to zero

and see if there is any difference?

Some more feedback regarding stutters here, Open Beta 2.8.6.xxxx using Multithread.

Got much better results than tweaking with Afinity and Priority processes at task Manager, getting rid of stutters on my PC was :

- at DCS menu > options > system > Textures  ...  changing from High to Medium

Hope it might help anyone, I don't recall the last time I played DCS so fluid.

Disabling Hot Plug was a real gamechanger for me, Thank You again, Bignewy

Did you have USB sound devices like USB DAC or USB headsets?

If disable Hot Plug solved your issue. it means that in your system, there are malformed devices disturb the Windows kernel.

will you share your all of your  peripheral devices and PC spec. so we may know what device and brand we should avoid.

No, I don't have any USB sound devices at all. I have a Thrustmaster T Flight Hotas as the controller. And the Bluetooth - mouse...

I see.. I have noticed Bluetooth input devices powersaving and sleep/wake up indeed creates a spike each time the hotplug enabled.

how often does it stutter on your machine.

This is crazy, from reading all these post on this matter seems like alot are reducing there graphic settings. Is this what we have to do now to play this game when before it was working fine. We shouldn't have to do this. If we have to play it with poor graphic settings now then they have lost me.

I have asked before but I would suggest you post your dcs log, dxdiag and if a particular scenario creates problems post a track replay also. 

Please do it in your own thread as it will just get lost in these general threads. 

If we see your system spec and setup we maybe able to help you. 

And as for lowering settings I do not think that is the case, it certainly wasnt for me when MT became a thing, I started increasing settings even in VR. 

thanks

Can’t confirm either. If anything, the general performance keeps increasing* comparing apples to apples. Of course sometimes new features gets introduced that take a toll if you use them.

(*excluding unsolved issues that might have appeared. But unlike some people,I personally have no doubt that ED is working hard on solving those - in their own interest).

To: Insonia: I didn't noticed any "regularity" in stuttering. I need to verify the dependence of the stuttering on the e.g. engine running... As I was connected to the MP server with many people, everything was supersmooth. After spawn to the plane, I noticed small stutters and after startup, there were more stutters, even after takeoff. Generally, the stuttering (in my case) appears occassionally, when passing more objects of the scenery at the same time or flying in formation. In SP, when hotstart on ground, "rotation" in F2 view is smooth, the same in the cockpit. In SP with coldstart, the same behaviour as in MP...

This 100% cured stuttering in DCS for me:

Device  Manager | Software devices | Microsoft Device Association Root Enumerator (Right-click and Disable). This driver is only needed for really old hardware and can be re-enabled at any time.

Thanks for your feedback.  I see this workaround is already used with other games.

Out of curiosity, what is your PC CPU?

Oh, and welcome to the forums.

Hello,

Thank you for the advice.
Although my PC is highly outdated, any help is useful.

By the way, how does this driver hinders DCS performance ? Does it consume RAM or any other resource ?

I guess we all want our beloved simulator to work flawlessly.

Even in Wags' video's we see the ground stutters. So i would not spent too much time on optimising your own. Just enjoy the sim as much as you can.

I feel it is not up to us to solve this issue nor find the root causes.

I would highly appreciate a response from ED from a technical perspective on the root cause(s) and when they expect to fix it (or not).
It should not be too difficult to debug the frame-time and understand which feature causes it to extend the target set by a certain FPS.

I've finally opened a ticket asking them exactly the same. At least they could inform us about the status or something.

We all spent a lot of money in to it!!

I've noticed that I’ve stuttering only if I forget to leave it on power saving

[Lixma 06]

Quick vid on what I'm seeing. Textures on MED, terrain textures on LOW, 8GB VRAM.

Seems to load textures (slowly) at close range, and then 'forget' them once you've flown away.

Your FPS seem to be capped at 60. Are you using V-sync or are you capping them ny the in-game fps slider?

Perhaps some creative testing is required here.  Does the issue occur when the merging aircraft are the same as the player module?  Does the issue depend on the size of the merging module?  Does the issue occur with merging rotor and prop modules?

 

i like your idea...I was having an issue...unrelated to stuttering...but some lateral thought...a few days of, back to basics...and I found the anomoly...

It can be really simple...a MOD you forgot you installed, I was having crash to Desktop issues a ways back...eventually we tracked it down to a small GPU Overclock...that I had done in 2019 !!

Something Unique to your system is doing this,,,...

V-sync

[Hiob]

A thing that I noticed and that seemed to help at least some folks was, making sure that a fps cap (if used) is not enforced by DCS, but by an outside app (best results so far with Afterburner/Riva Statistics - gives the smoothest frametimes).

So leave the FPS slider at 180 and cap the fps with Riva below that (depending on your hardware), e.g. 120.

The FPS-Slider was introduced with the same patch that introduced the frametime spikes if I'm not mistaken. (Could of course be a coincidence).

The reasoning behind that (as far as I can make sense of it) is, that a fps-limit is probably be enforced by the main render thread and maybe that is upsetting something. By moving that task to a third party application, DCS is free from that burden.

Hello guys I seen some talking about disabling power server how do u do this in windows 10 . By doing this it could help the stuttering is what it sounds like am not sure any help out

[Hiob]

open the start menu and type „services“. Open the app and search for a service called power (or similar when you are using a non-english version of windows). Right click on it and stop/disable it. That will stop all power saving functions, so be mindful if you are using a notebook. You can enable it the same way around.*

*by the way, the reason this service can produce stutters is not the power saving in itself, but the myriad of system calls/interrupts it unnecessarily produces….
