{% endhint %}

### Issue:

* Twinmotion crashes when exporting high-resolution renders.
* Twinmotion's crash log shows "GPU Crash Detected".
* Twinmotion's crash log shows "GPU crash dump triggered".

### Affected versions:

* Twinmotion 2025.1.1 or newer.

***

### Cause:

Windows contains a Timeout Detection and Recovery protocol which detects response times from the graphics card. The default value is 2 seconds which conflicts with Twinmotion's timeout values, when performing time-consuming, high-resolution exports.

***

### Fix:

**Increase the Windows timeout value to 60 seconds to align to Twinmotion's values.**

3. Navigate to:
4. `Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers`.

   ![](/files/Bhvg2CrLcF60dIxec8XN)
5. The registry key you need is called `TdrDelay`. If this registry key already exists, double-click to edit it. If it does not already exist, right-click in the pane on the right and select **New > DWORD (32-bit) Value**.

   ![Create a new DWORD registry key](https://d1iv7db44yhgxn.cloudfront.net/documentation/images/4744e353-a524-4113-bf21-45ab186d3f90/new-dword.png)
6. Set the **Base** to **Decimal.** Set the **Value** of TdrDelay to **60**. Click **OK** to finish.

7. Right-click in the right hand pane and select **New > DWORD (32-bit) Value** and create a 2nd key.
8. Set the **Base** to **Decimal.** Set the **Value** of `TdrDdiDelay` to **60**. Click **OK** to finish.

9. Your registry should now include both `TdrDelay` and `TdrDdiDelay`.
