Twinmotion powered Unreal Engine 5 ? or 4?

I read Faq "Twinmotion is a real-time visualization tool powered by Unreal Engine"

Twinmotion powered Unreal Engine 5 ? or 4?

Please tell me that.

Twinmotion 23.1.2 is powered unreal engine 5 therefor you needt a RTX Grafikcard to use all renderfunktions. Older Versions 2022 using unreak engine 4 still support all renderfunction.

Thank you so much🙏
