Twinmotion 2024.1 is Very Sluggish

Twinmotion 2024.1 is very sluggish when opened (FPS = 0, both GPU and CPU usage = 100%).
I also have an older version installed (Twinmotion 2023.1.2) and it runs just fine!

Why is my FPS at 0? Why is my GPU and CPU usage at 100%?

Specs:

  • Windows 11 (64-bit)
  • NVIDIA RTX 3090
  • AMD Rayzen 5 5600X 6-core Processor

I have tried uninstalling it, cleaning out windows registries, changing GPU settings, changing preferences in TM, etc, but none of the actions fixed it.

Here is what I see in my statistics window from TM 2024.1. I deleted all objects from the starting scene but that did not help!

Here is a screenshot of my TM 2024.1 empty scene

Here is a screenshot taken from an older version of Twinmotion (2023.1.2) … on the same computer showing everything working just fine.
