Game crashing on launch with RTX 5070 Ti – Lost-Device error

[Sidruxell]

Hi,

I recently upgraded to an RTX 5070 Ti and now X4: Foundations crashes a few seconds after launching with the error:
**"Failed to recover after a Lost-Device"**

What I’ve tried so far:

* `-windowed`, `-borderless`, `-d3d11`, and `-fps 60` launch options
* Disabled Steam, Discord, and GeForce overlays
* Clean driver installation using DDU
* Tried both latest and older NVIDIA drivers
* Resizable BAR is **disabled** in BIOS
* Hardware-Accelerated GPU Scheduling **disabled**

No crash logs are generated in `Documents\Egosoft\X4\logs`.
However, Windows Event Viewer logs multiple errors from the **NVIDIA OpenGL Driver**:

```
The NVIDIA OpenGL driver has not been able to initialize a connection with the GPU.
This might be due to out of memory error, an exhaustion of system resources or too many graphical applications running.
```

My system:
DxDiag summary:

OS: Windows 11 Pro 64-bit (10.0, Build 22631)
CPU: Intel Core i7-12700 (20 CPUs)
RAM: 32 GB DDR4
GPU: NVIDIA GeForce RTX 5070 Ti (Driver Version: 552.22 - DCH WHQL)
DirectX Version: 12
Resizable BAR: Disabled
Display Mode: 2560x1440 (144Hz), G-SYNC Capable


The game worked fine even with the new GPU until recently. Now it crashes consistently.
The game crashes with error "Failed to recover after a Lost-Device", possibly linked to OpenGL/Vulkan and 5070 Ti driver.
I've tried all official launch options and verified ReBAR and overlays are off. Any ideas?
Any help is appreciated!

We need the full DXDiag, not just a summary. Please see the very first thread at the top of the forum. Taking a wild guess, however, the latest NVidia drivers have been reported to cause some problems, and you may find that rolling back to a slightly older version may help.
