Stutters on 9800X3D 96 RAM in MP

I'm talking about the voltage curve

I’m not undervolting, so it’s just the default settings. My temperatures stay low because I can hear that by the sound level of the fans. I have a custom fan curve that lets them speed up when the temperatures reach high levels but that doesn’t happen in DCS (other than due to a bug a while ago that was fixed).

According to he's OP, he's not using VR but TrackIR. Just mentioning it.

Gotcha, got my wires crossed there.

I'm pretty sure it's not about the Windows settings, because with the same Windows settings, I used 2 different processors and there were statters on one, but not on the other. 

That sounds like you swapped the hardware without reinstalling windows? AMD CPUs require very different things from the windows scheduler than Intel CPUs. When doing a complete reinstall, it’s very easy to forget something in windows, so I’m just making sure

I thought so too, and after that I reinstalled win 10 - it didn't help. after that, I installed win 11 23h2 - it didn't help, then I installed win11 24h2 - it didn't help.... Now I'm thinking of trying 25h2, but there's little hope. There were the same lags at all stages.

My spec Ryzen 7 9800X3D, 96 RAM (6000 GHz 30 CL), 4070 ti (12 Gb), SSD - Samsung 990 PRO 2 Tb.

I have small stutters in the multiplayer. And it's very annoying. This happens most often on earth and when there are many AI scripts on the map (for example, 4YA servers). I've tried on Growling Sidewinder server (just take off) and it will be fine

What I've tried:

• I set the graphical settings to minimum, but it didn't help
• enabled/disabled SMT in bios
• turned on/off EXPO
• overclocked the RAM
• limited FPS (120/ 80)
• turned off the first CPU core
• disabled core parking (C-State - off in Bios)
• reduced the mouse frequency
• turned off my Virpil deviсes and TrackIR
• G-sync on/off
• Fullscreen on/off

What else can I do?

a screenshot from the 4YA server (Iraq), there were only 4 players. But on the map of the Caucasus, where 30+ players are the same.

You mentioned this was in multiplayer. Are you completely stutter free in single player as well?

I'm asking because this is a major way to diagnose if it is an issue with your system instead of the multiplayer performance of DCS in general.

I've been playing DCS for 11 years on 5 different systems. They were all Intel based until I switched to a 9800X3D about 7 months ago and I've been quite happy about it.

That being said, stuttering in multiplayer in DCS has always been an issue for me and a lot of people. Especially when the server gets overloaded. The server can list 64 people as maximum amount, but it seems like when it is around 30 to 40 plus players the stuttering gets really bad.

Switching to a 14700K from a 9800X3D isn't going to make your stuttering problem better, it will make it worse. Especially if you are not having issues with it in single player. Also, the majority of 14700K chips are defective. Mine started failing after only 4 months and it wasn't overclocked either. There was a defect in the manufacturing process when Intel was making those chips. Some people have issues from the first day of install, some have gone a year or more with no issue. It will at some point most likely fail either way. That is why I replaced mine with a 9800X3D chip.

You can set your graphics setting to low, medium, or high but there a couple specific settings that greatly impact stuttering from my observations. Those settings are SSLR and civilian traffic. I don't know why these settings give me stuttering on the 9800X3D in single player, but they do. I have turned off both settings and DCS still looks absolutely stunning on my 42-inch 4k monitor. I will attach a screenshot of my settings for you to look at in this post.

I have had stuttering issues in single player in DCS due to my RAM as well in the past. The 9800X3D seems pickier with RAM than on Intel chips in my experience. I have gone through three sets of RAM on my latest PC before finding a set that worked well. It was the AMD specific G.Skill Trident 2x32 6000mt's RAM. The first set of a RAM was a 4x16 6000MT's set from TeamGroup and my machine did not like it all. It gave me a lot of blue screens, stuttering and crashes in DCS and other simulators and games. Second set was a 2X48 4800MT's set from Corsair that would overheat and give me the same issues.  

Have you updated your processor and chipset drivers for your 9800X3D from the AMD website as well? You need to do it for both categories if you haven't. It makes a major difference also.

Also, make sure you do not have Ryzen Master, Nvidia Experience app, or ASUS Armory Crate installed as well. These programs eat up resources in the background. In the case of ASUS Armory Crate, you will want to reinstall your entire Windows install and make sure not to install it again.

Lastly, sometimes when loading into a server the VRAM on your graphics card can go over budget when loading everything in and needs a little bit of time to release it. This is more noticeable on some of the higher detailed maps like the Sinai map for instance. You might notice some stuttering or hanging during that time as well.

I get confused, as there are some similar threads around the past few days.
You completely wiped the disks and installed a new version of Windows, or you upgraded? There's a way you can completely refresh Windows without reinstalling. Similar to a full repair of DCS.

The stutters when players join/disconnect is very intermittent. It will only happen on some servers, and only some of the time. You mentioned using your wifes machine earlier, you might want to try having both machines logged into the same server at the same time if possible. You will likely see them both stutter at the exact same moments.

A server like growling sidewinder for example is far less likely to have any of these join/disconnect stutters, but a more busy server like 4YA will have them more often. Particularly if 4YA are still using non dynamic slots, I haven't checked in a while if they're still on the old slots or not.

that's exactly what I did, logging into the same server from different PCs. I have very strong lags (drops from 120 to 20-30 fps), she also has lags, but much less (drops from 120 to 105-110 fps)

I always perform a clean installation.

I've been trying to solve this problem on my own since June. I've been trying to solve it with DCS support for the last month...now i'm here

@Av8trI don't see any lags in the single version.

all drivers are updated to the latest versions (even tried beta versions)

if I set all the settings to the absolute minimum, the situation does not change. at a minimum, 2 GB of Vram is used out of 12

If you don't see any lag in singleplayer then it is just an issue with multiplayer in DCS in general. It's been around since I started playing DCS in 2014. Sometimes it gets better during certain updates and other times it gets worse. The only time I managed to get rid of stuttering in multiplayer was during a brief moment during DCS 1.5 when I bought 128gb of RAM that I used on an older PC.
