Hello, ,
Here are the things to check:
- GPU Driver are updated
- Windows version is updated to at least 20H2, 21H1 or 21H2 (Go to Windows Setting -> System -> About to check)
If you have more than one GPU also follow the instructions in this article to make sure you are using the correct one. https://twinmotionhelp.epicgames.com/s/article/Use-your-dedicated-GPU-with-Twinmotion-on-a-Windows-computer
