Constant crash: Unreal Engine is exiting due to D3D device being lost.

Hi from France 🙂,

I read yesterday your conversation as I was a brand new impacted user. I build my new PC this week and launched JFO which seems to be fantastic. But after 3 to 5 min, I suffered from a recurrent error, just enough to avoid any save on the first mission 😬

Windows event :

The description for Event ID 14 from source nvlddmkm cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

Origin popup :

LowLevelFatalError [File:Unknown] [Line: 200] Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0020 - 'INTERNAL_ERROR') etc .....

Here is the detail of what I run :

MB : Asus B450-i ROG STRIX GAMING - Mini-ITX

CPU : AMD Ryzen 7 2700X

RAM : Delta TUF Alliance RGB - 2 x 8 Go - DDR4 3200 MHz

GPU : MSI GeForce RTX 2070 VENTUS GP - 8 Go

GPU driver version when KO : 432.00

GPU driver when OK : 445.75 (see installation below - it's important)

First try : Update Nvidia Driver from 432.00 to 445.75 using GeForce Experience

Result = still KO

Possible reason : Updated driver may contain old files, or parameters. I suppose it is not clean enough to resolve my issue.

So I decide to apply a bundle of every solution I found on Google and for now everything works fine (3 hours session yesterday, no occurrence). Hope my actions can help you :

Second try

Step 1 - Fresh Nvidia driver installation

Necessary softwares (both free) were DDU (Display Driver Uninstaller) and  Registrar Registry Manager

Remove existing driver

1. Restart your PC in Safe Mode
2. Start DDU
3. In options panel : Select the option which does not allow Windows update to auto install a new driver.
4. On the main page : Select GPU and NVIDIA
5. Clic the top button. In english it should be something like "uninstall and restart (recommended)"    //sorry my DDU is in french

Remove any Nvidia register entry to make it disapear (key step)

1. Start Registrar Registry Manager
2. On the left panel, make  the following research :
   • Type of search = Plain text search
   • Text or data to search for = Nvidia
   • Where to search = Registry
   • What to look for = key name + value names + data
3. Select all (ctrl + A) and "delete selected keys and values" (important : I read sometimes that you must exclude 3D software, or games entries.Personnaly I did delete ALL but I am not responsible if it broke some functions - registry is a tricky thing to modify so be carreful please)

At this step, I recommend a new restart of your computer, to make sure that everything is clean.

Once done, install the last Nvidia driver available : for me yesterday (April 2020) it was 445.75 so the exact same version than my first attempt which was KO but this time fresh and clean.

Step 2 - Disable PCIe power restriction

Out of the box, Windows 10 try to limit the power consumption of your PCIe components. To make sure that every Watt are delivered, I changed this option do deactivated any power energy mode (sorry french screenshot but understandable 🤭 )

Step 3 - New registry DWORD value

To add some tolerance on the driver behavior, I manually changed 2 defaults value in registry (default values are not visible in regedit, you need to create 2 new DWORD entry)

First, increase the default Timeout delay from 2 sec to 5 sec :

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers]

"TdrDelay"=dword:00000005

Then, switch the debug mode from recover to recover unconditionnal

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers]
"TdrDebugMode"=dword:00000003

Once again, you can restart and please let me now if it help you. Good luck everyone

phenomenal tutorial! Thanks 🙂

Thanks, will try it out! 

I reverted to driver 442 and it works. Sadly, it crashes a lot. Just now I even got BSODed. ☹️ 

I'm not happy with my purchase.

Hi,

It's been 5 days since my previous post, and after 20 hours of intense gaming the situation remains stable : no crash at all (and this game is insane 😎 )

Please keep me posted, I am quite interested to see if I am just lucky.

I rebought the game today for Star Wars day.

Crashes in normal configuration still occur very frequently (current windows 10- 64bit / current nvidia driver 445.87).

So I did some more troubleshooting:

What helps in the configuration:

- borderless window instead of full screen (fixes crashes, but performance deteriorates quite a lot)

- reduce shadow detail to medium (crashes occur less often, but they still occur)

What I also did, is installing from these nexus mods:

https://www.nexusmods.com/starwarsjedifallenorder/mods/9?tab=description

- no intro fix (unrelated to crashes, but SIGNIFICANTLY reduces load time with a much bigger impact than moving the game from the HDD array to SSD)

- CustomEngineNoAA - this fixes the game for me so that there are no crashes (or almost no crashes, need to test further) and great performance, at the detriment of some visual effects

Oddly, I found one other game in the meantime, which shows a similar crash behaviour while running in full screen mode:
Jurassic World Evolution (runs on Cobra Engine, with a significant performance penalty when running in windowed mode)

all other games I have run fine without any stability issues.

Edit: I also followed Swatouille's extensive action plan, which unfortunately didn't make any change for me.

Edit2: AA is the one key element that seems to break the game for my setup. Forcing AA off as described here: https://steamcommunity.com/app/1172380/discussions/0/3342162929518454596/

allows me to play without any mods (pak files).

Note: if you change any visual settings in the GUI, the ini file will be overwritten and you have to edit again. You cannot set "0" via the GUI.
