Twinmotion crashes when exporting high-resolution renders

Created from EpicGames documentation.

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.

Perform these steps as an Administrator.
