DX device removed. Reason: 0x887A0006 9x This week.

VPS_MCOY · May 17, 2023

Hi all so since the last DCS update I'm desperate to find a fix for this issue, | have had this 9x this week, its only on DCS, I have done rolling back drivers, registry edits told to me by DCS support, turned on debug mode on the gpu to try and get rid of factory OC, I have no more things to try

DX device removed. Reason: 0x887A0006

ASUS Strix 3080ti

Does anyone have any ideas and is anyone experiencing the same issue as me

Thes solutions below helped some forum users with this issue. Give them a go.

If you're using GeForce Experience, disable its performance overlay.
If you're using MSI afterburner, disable it before playing.
If you're using a Gen3 PCI riser with a Gen4 CPU, well don't.
If your RAM is overclocked (XMP), set XMP off and see if it still crashes.
Rename your Saved Games/DCS.../Config/options.lua to "options.lua.bak".
If you're using Aorus Graphics Engine: disable autoscanning (auto OC).
Ensure Windows power plan setting is correct (default or High).
Disable Asus GPU Tweak if you're using it.
Disable MSI Center SDK if you're using it.
If DCS is windowed, and NVIDIA G-Sync is "Fullscreen", set NVIDIA G-Sync to "Fullscreen and Windowed".
Rename Saved Games/DCS.../Config/autoexec.cfg to "autoexec.cfg.bak".

not even sure what that is, with regards to changing the saved games names are we supposed to test it at them settings or adjust back to what we was prior

PanosI · May 19, 2023

Windows 11 Home here

I believe Windows N version was made for the European market. It consists in a slightly lighter Windows, which does not comprise a few tools. A user recently discovered he had to install the missing tools to prevent DCS from crashing, hence my question.

You can adjust the settings at your taste. Just don't reintegrate your export scripts, liveries, mods.... just yet.

Not sure I'm windows 10 x64

VPS_MCOY · May 19, 2023

I have done , System file check as well told to me by the guy's I purchased it from and still just had a crash again

Flappie · May 19, 2023

Try to run this command in a "cmd" window:
MFStartup

If it throws an error message, then you're using Windows "N" version. Otherwise, you have a standard Windows.

@VPS_MCOY Can you please attach the latest zip file from your Logs folder? I can't open RAR files with my phone.

@Flappie

Can you, please, also take a look at my zip file since i have the same problem and DCS is unplayable ?

@PanosI Same error indeed, but I don't know what triggers it.

Did anybody ever solve this? Same issue.

Everything worked perfectly the last time I flew. There were 2 back to back updates since then. Now, the game freezes 1-5 into gameplay. I've tried everything and it's just broken now.

WTH ED?
