It's an UE5 demo, so probably needs an RTX with 8GB vram at least. If I could finally download it, I'd tell you how it runs on the RTX 2060 Super 8GB. (sadly this is just the bare minimum for the current gen anyways)
Edit: For the most part, it ran around 25-35fps at QHD native and 30-45fps at FHD native. However, the intro cutscenes were very choppy at below 20fps framerates, late texture pop-ins etc. The ending scene with the heavy volumetric effects was around 20-25fps. In my opinion, adding a few graphics settings and optimizing a few scenes would boost the performance a lot. Even just DLSS upscaling and an option to reduce the biggest bottlenecks would make it much more playable on modest hardware.
