Twinmotion 2022.1.1 Crashes after a min of use or after loading any project

imzapper · April 29, 2024, 2:26pm

I'm getting errors such as these:

Fatal error: [File:Unknown] [Line: 684] hr failed at D:/tm/workspace/Release-2022.1/Engine/Source/Runtime/D3D12RHI/Private/D3D12Resources.cpp:488 with error DXGI_ERROR_DEVICE_REMOVED with Reason: DXGI_ERROR_DEVICE_HUNG

Twinmotion_Win64_Shipping

kernel32

ntdll

My pc is brand new built specifically to harness twinimotion's real-time rendering.

Windows 10 64bit

AMD Ryzen 5 5600X

NVIDIA GeForce RTX 3060

Corsair Vengeance LPX 64GB (2x 32GB) DDR4 3200

SAMSUNG 970 EVO Plus SSD 2TB

Any help would greatly be appreciated.

Hello ,

Thank you for posting in the community and we have a workaround documented in an article that should avoid having these crashes. If you already tried to follow those steps then try to increase the Tdr Delay from 15 to 30.

Hi Vincent_B,

Thanks for the link. Unfortunately, after following the directions in the thread you posted I am getting the exact same behavior, with the exact same crash report.

I've already reported the issue and been suggestions to turn off path tracing, which isn't on and almost all projects never even load in before crashing.

Before you suggest a potential corrupt file, the same thing happens when opening the demo Lake House. I'm Starting to regret building a pc for twinmotion ):
