Crash Help Please.

[Martallica]

Getting lots of crashes lately. Every thing is up to date. This might be a psu problem, but I don't know so any help would be much appreciated.  dcs.log-20250221-205600.zipdcs.log-20250228-220245.zipdcs.log-20250301-205100.zipdcs.log-20250301-230725.zipdcs.log-20250315-224546.zipdcs.log-20250322-221646.zipdcs.log-20250329-215325.zipdcs.log-20250329-221107.zipdcs.log-20250405-205826.zipdcs.log-20250411-185811.zipdcs.log.olddebrief.logdcs.log

Do these crashes happen at the same point each time?

If you think it might be the psu (or any component) have you tried running a stress test program?

[Martallica]

No they happen pretty randomly, but always in campaigns.

I didn't stress test cause I'd imagine I'd need to have all my winwing stuff plugged in and running, but I suppose I should do that?

I do have powered USB for HOTAS,MFD's UFC and Screens.

@Martallica Out of curiosity what size PSU do you have, and when you say crash - is it just DCS or the whole PC goes into a shutdown/reboot? Where is the power to the USB coming from - is it a separate mains supply or also out of the PC?

Have you upgraded anything recently (either software or hardware), and tried removing any mods you may be running?

When you say campaign - which one and which aircraft are you flying?

I had similar last year and it was purely down to overheating - initially fixed by popping the side of my case off and directing a small USB powered fan into it. Permanent remedy was to upgrade my cooling fans in my case (and hoover out all the dust from the intakes!). 

 

[Martallica]

It's a 850w Evga, just DCS 90% of the time but sometimes the PC will restart. The USB hub's have their own mains power supply.

There's nothing up graded on the PC but I have added a third winwing screens and MFD recently.

I fly the Hornet and Viper as for Campaigns WOS 1 and 2, Arctic Thunder F16 and F18, but those where crashing so I thought I'd try an older one, so I got Rise of the Persian Loin but this was worse.

Heat is not a problem. My system has a water loop and never gets higher than 65c ( 150F ) on the the CPU or GPU.

I clean and blow out the PC regularly and I've updated the Bios, windows and GPU.

By the way The GPU is a RX 6800 and the CPU is a Ryzen 7 5800x and I've got 32 Gb of ram.

@Martallica hello. i dropped your log from 4/11 crash into analyzer.

Errors

Hot plug Events
Disable hot plug in your CONTROLS section.
Your DCS has crashed
The crash occurred inside edCore.dll.
PLEASE REMOVE ANY CUSTOM MODS FIRST AND CHECK,
IF THE ISSUE PERSISTS!
If that does not help:
Try a !repair.
Delete Saved Games\DCS\fxo and metashaders2 and try again.
Next, delete %LOCALAPPDATA%\TEMP\DCS and try again.
Next, try renaming Saved Games\DCS to DCS.old and try again.

Carry out the suggested repair steps one after the other.
If all fails, open a !support ticket.

Tuning Tips

Set Preload Radius to max. 60000.
Tuning tips are recommendations for better FPS based on your CPU, GPU and RAM.
They might result in slightly decreased display quality.

@Martallica In addition to SilverDevils - are the crashes occurring only after adding the third MFD? Just a thought if thats been added and then the crashes started occurring? 

PSU 850w should be enough but not sure of the draw of all your various peripherals? PSU failures can be a pain sometime to troubleshoot. I have been adamant my GPU was up the swanny previously due to the symptoms and it turned out to be the PSU.

[sleighzy]

Numerous varying issues showing up in those logs. There is one from your Winwing scripts, although a rename of the Saved Games would remove that script, I don't know if it's related. The Winwing script errors seem to show up around the same time and the error stack trace of the crash does indicate doing something with lua. This is the Saved Games\DCS\Scripts/wwt/wwtExport.lua file.

Other issues from the DxDiag logs:

Memory Timing Issues

• Remove any overclocking (XMP) from your RAM.

 

The DxDiag logs show issues for Winwing, TrackIR5, SimAppPro, WWTStream so potentially a larger problem overall.

Repair your Windows by running the following each of the following commands and then restarting your PC. These need to be from a command prompt run as administrator.

dism /online /cleanup-image /restorehealth

sfc /scannow

 

Also noted in the DCS log analyser from the DxDiag logs:

Microsoft Update / Store issues

• Make sure you have enough free disk space.   (based on your logs this looks to be fine)
• Run the wsreset.exe command in a command prompt to reset the Microsoft Store cache.

 

I also see you have dropped your own dxgi.dll file in the bin-mt directory, there's only a couple of reasons for doing this, but could potentially remove till this is resolved.

Speaking of the bin-mt directory this is now just for backwards compatibility as DCS is all multithreaded. Use the DCS exe (or standard DCS shortcut) for the one in the bin directory. There were also known issues with Winwing MFDs if running DCS as administrator so if you're using your own shortcut then make sure "Run as Administrator" isn't ticked on the compatibility tab of the shortcut.

The log analyzer also says to disable hotplugging in the DCS controls settings. This may already be disabled (disable if not) in which case it can be due to USB power issues. I can see unplug events for TrackIR in one of the logs. You mentioned a PSU power problem, and have a lot of peripherals plugged in. Also turn off power management in Windows Device Manager for your root USB controllers.

Leg2ion touched on this above. Could try unplugging these additional peripherals and see if the issue persists.

Thank you so much for all the help guys, I probably wont get a chance to do anything till Wednesday, but I'll get back to let you all know how I get on asap.

Mine crashes when I launch a weapon behind an enemy player. I am starting to suspect the 'C' word and not an ED problem.

The game can crash for users for many many different reasons. I’d recommend you raise your own post along with the DCS log file containing this (and other dcs.log-<timestamp>.zip files) for this. Alternatively you can drop them in the Eagle Dynamics DCS Discord server in the #dcs-log-analyzer channel.
