If any of you guys would be so kind and provide a simple dcs.log, that would help a ton. Screenshots unfortunately don't help at all. => For the guys using E-Core CPUs, please make sure that you are on Windows 11 and that core parking is disabled. => For the guys using Ryzen CPUs, please make sure that you do not have MSI afterburner installed. Happy to look at any log, if provided.

You're completely hijacking a report for a different thing. I have seen that also. It happens with many AV solutions when the scanner for whatever reason takes a ton of time to scan. I assume you've created an exclusion already and you're on windows standard?

The ones of you that use TrackIR, you might want to check if you downgrade to an older software version. There are a lot of complaints about the latest one together with DCS.

Yes, but you can not reproduce it yet Fingers crossed though!

Yes, there is a known critical issue with MSI Afterburner and AMD CPUs.

2024-12-29 20:02:05.013 TRACE SECURITYCONTROL (42148): do_check_resource(mods/aircraft/a-10c_2/bin/a10.dll, ) ... 2024-12-29 20:11:54.019 INFO EDCORE (Main): Loaded F:/Program Files/Eagle Dynamics/DCS World/Mods/aircraft/A-10C_2/bin/A10.dll It takes 9 minutes (!) to load that DLL. Which antivirus do you use? And do you use MSI Afterburner by chance (have it installed)?

Ok, upload this file to Saved Games\DCS\Config, recreate your issue and send me the new dcs.log please. autoexec.cfg

Which antivirus do you use?

It can be that you have no issues at all, but usually if you use any other application that uses your GPU, which can be Discord or YouTube, you can see stutters. That is why I usually ask to turn it off.

You need a pagefile, that was not a good advise. Windows virtual memory management is built around pagefiles. And you still want to have valuable RAM available and long-time-no-see RAM pages paged out, even with 64 GB. You can have it on system managed though. Do you have resizable BAR enabled?

Do you have core isolation, game mode and hardware GPU scheduling disabled? Have you tuned your Nvidia 3D settings also? The rest is looking quite ok. Your pagefile (even if it is not needed that much) is on a fast NVMe? If you like, you can send me your dxdiag.txt also.

You're using mods and they crash your DCS, especially the Su30. Same issue.. Su30 mod. Guys please, whenever you encounter these issues, the first thing you need to think about is removing the stuff you did to DCS.

Can you get me your dcs.log please? I have 5 PCs with different hardware now here, from potato to powerhouse, VR and non VR, I don't see that. And I don't have stutter on my two real gaming rigs.

You better disable core parking than telling the CPU to check it more often in my eyes.

Fair enough. It is the only OS where Microsoft puts their love in atm. There were issues, yes, with the first versions, but currently it is very stable. Vendors tend to apply only changes to Win11 these days, as you see with AMD. CPUs with E-cores are not even properly supported on Win10, which does not hit you in this case.

Sorry haven't seen it earlier. There were some significant performances improvements by AMD that they only applied to Windows 11, so I would assume that yes. It's a completely different story than with the E-core CPUs though.

Run a windows tool named dxdiag, press save everything and send the resulting dxdiag.txt Try again with Debug logging enabled. For that, put the attached autoexec.cfg in your Saved Games\DCS\Config folder and recreate the issue. Send a new log please. autoexec.cfg

Because DCS MT knows which cores are P and which are E. Look at the startup and you see that DCS detects the performance class of each of your logical cores and it then decides which ones to use for what. Unless you are on Windows 10 (which doesn't make much sense with these CPUs, but I see that every day), you can use them with DCS.

64 GB is always better than XMP. XMP does not give you much, some single digit FPS maybe, unless your system is completely unbalanced.

You always need a pagefile, but you can keep it on system managed with that setup. I use the smoothing with my Pimax, and have quite good results with it. The lags and jitter come for me, if I try to achieve some FPS that my GPU can't handle.

Looking at your dcs.log there is a bit more to do: - Turn off SSLR. - Turn off SSAO. - Disable civil traffic. These are expensive things. Delete Saved Games\DCS\fxo and metashaders2 also. And increase your pagefile. You want at least 32, better 48+ GB on your fastest drive. Only one pagefile please.

No, these settings are all Windows. Do NOT disable any cores, do NOT use Process Lasso anymore on Win11. The MT stuff is running quite well now without.

@Panzerlang I see a lot of Bluescreens in your DXDiag and that you ran Prime already (which crashed also). It looks that you have some timing issues. Have not checked the latest BIOS for that board yet, but that is worth to check. On the other hand, check please if you have - Game Mode disables - Hardware Accelerated GPU Scheduling disabled - Core Isolation disabled - Core parking disabled

Yeah, I doubt you installed it, as you would know, if you did. Can you try one other thing: Go to C:\Users\<yourusername>\AppData\Local\Temp and delete the DCS directory in there. See if that makes any difference.

Try and run a slow repair with check extra files. If it would have been there, it should be removed. Do you use the OpenXR Toolkit by any chance and if yes, did you try to play without already?
