Guys i think finally i found the issue...

 

Whenever i start DCS with TrackIR running, it freezes but without TrackIR software running it all just works normally

I don't have an TrackIRr, but the problem is the same. There's a whole topic about this, but it's in Russian.

This happened to me when I updated TrackIR software.I reverted back to an older version and keep it that way today. Using 5.4.2.27545.

Use the "Park Control" program and your problem will be solved.

No effect on the freeze for me, with or without park control. The logs also don't show any cores being parked.

 

It freezes with and without trackir for me as well.

Game is still freezing as of update 2.9.15.9408 logs attached. Can someone from ED please weigh in on this issue Multiple threads have been started, across both Russian and English language forums, several people on discord have encountered this same issue. I have been through the ENTIRE Crash trouble shooting guide, with no success. This issue is completely sapping my enjoyment of the game.

@BIGNEWY @NineLine 1) Are developers being aware of problem? None of any visible reaction so long.
2) what "pause10: xxxx cycles" value in logs means? Those who have that problem seems to have high 'std dev' on this line

This seems to be the culprit.

I had a similar problem solved here

 

I think there is something about USB high speed pooling and DCS core utilization at the same time. Try removing all gaming peripherals and replace with a simple cheap mouse and keyboard.

Can you please replicate the issue again and then drop a DCS log file here. Will help identify if there are common issues being experienced across these reports.

Can you drop a DCS log file here with this occurring without TrackIR.

Can you also run the Windows DxDiag tool, save the output report and drop here as well.

So i recently updated to windows 11 and the issue went away for several weeks but it just came back, I had my game freeze my whole system in the mission editor again today. This is with track IR running however, I will try replicate the issue without trackIR but in the past I have been able to get it to freeze without running trackIR I just didn't save the logs at that time as I was trying all sorts of potential fixes, and pulling my hair out. I will try and post it again if it happens without trackIR just to rule it out.

This JUST started for me yesterday. I made a lot of options changes so I need to go back and figure out what might be causing this.

I've also encountered this problem, and it's really frustrating... I've tried disabling kernel isolation, adjusting CPU affinity, turning off XMP, changing the power policy, disabling core parking, reinstalling the entire game, upgrading to Windows 11, updating the BIOS, cleaning the memory modules, changing the mouse polling rate, deleting shader files, and using Steam to repair the game files. I've even modified the in - game graphics settings one by one for a control experiment... All these actions have taken me a lot of time, and not only did they not work, but the problem got worse. Now, when I try to enter the game, there's a long black - screen loading period. Sometimes, even during the loading process, the system emits a beeping alarm sound and then freezes permanently. After the latest update, after I modified some of the above settings, a new problem emerged: Moving the mouse in - game causes a significant drop in frame rate, from 150 to 40+ or even 20+, and this is the case even in the main menu... All these things have taken up a large amount of my time. Especially in the past two months, I've been preparing for the Licensed Physician Qualification Examination, and all my spare time has been spent on fixing this game, yet with no obvious results. I'm tired of it and don't want to play this game for the time being until the problem is fixed.

To add, there will be a loud system beeping alarm before freezing. After freezing, all operations will not respond, but game music and voice chat can proceed normally. After the freeze is lifted, it can be seen from the Task Manager that the GPU usage was 0% during the freeze and one of the CPUs was at 100%. That's all for my addition.

Have you tried turning off virtualization technology in UEFI? Also if you want to narrow it down a lot more, rename your saved games folder and generate a new one. Dont delete the old one, just rename it. Delete the new one if this doesnt solve anything. After that, youll have to one by one replace folders from one to the other until problems start appearing again.

Yes, I disabled the Virtualization Technology in the CPU settings under the BIOS. However, after performing this operation along with several other actions, issues such as a significant delay in launching the game via Steam, a prolonged black screen before the game loads, and even the program becoming unresponsive emerged. (I'm uncertain whether this is caused by the aforementioned operation.)

 

Regarding troubleshooting by deleting the save folder, I've considered that as well. I've attempted deleting the DCS folder under the save game directory on the C drive and reinstalling the game to start fresh. Unfortunately, the problems persist when launching the game.

dcs.logHere is my log. During this login session, the following issues occurred: the launcher took an excessively long time to open, there was a prolonged black screen while loading into the game, and the game's main menu froze and resumed multiple times.

[Hammer1-1]

ok what was the beeping noise pattern?

Sorry, it should be a "dodo" sound. My description was incorrect. Anyway, as shown in the following video, once the DCS is about to freeze, it will occasionally get stuck and alarm before freezing.

[Hammer1-1]

thats an odd series of beeping and it definitely sounds hardware related. Start looking for issues in your device manager, try installing it on a separate disk drive not on your windows partition, and if anything try to install it on a new hard drive separated from the other hard drives. Id just remove the others - save for the windows disk drive and just go from there.

Yes, I’ve tried that too. I’ve installed DCS on both of my solid-state drives, but it didn’t improve the issue at the time. From what I’ve found through searching, this beeping sound might occur when the system freezes due to high CPU load

did you try removing one of those drives? I mean I get it...I spent the better part of 6 months trying to fix DCS with similar issues and being frustrated not being able to play. I rarely fly nowadays because of this stuff, even more so because of VR. It turned out that park control was the only thing I needed, started fresh with DCS and no mods on a fresh M2 drive WITHOUT VR...no process lasso either. Only need one program running in the background and thats windows. Could very well be Nvidia's app or GeForce experience too.
 

I havent tried DCS since the F4U came out, and even then only for like an hour. Havent even tried this patch yet, so honestly dont know what to expect, but Ill have to see for myself today too. Ill report back as well, but

My computer has two M.2 drives, and I’ve tried reinstalling (the program) on both, but neither worked well… The problem isn’t here. I recently tried disabling core parking, which did bring noticeable improvements. However, there are still occasional intermittent freezes, and a new issue has cropped up: occasional frame drops when moving the mouse. This can be fixed by restarting the game. (Forums point out that this issue stems from mouse polling rate, but I never had this problem before when using a 1000Hz polling rate.)

[EX_AI]

I enabled the option for the highest CPU priority, and the freezing issue has been significantly alleviated! However, the game's startup speed has slowed down noticeably. Does anyone know the reason behind this? Below is the comparison data; there seems to be a fundamental difference in CPU allocation.
 

The first image shows the scenario when the CPU priority is set to the highest.

 

The second image shows the scenario when the CPU priority is set to default, where the game gets stuck at the black screen loading step during startup or freezes after entering the main menu：

and the dcs.log file when it gets stuck on the black screen loading：dcs.log
