I modelled the arches in Rhino and grasshopper a while back, and imported to Unreal Engine 4, but I couldn't replicate the geometry as it was quite detailed. So I brought it back to UE5 now, and turned the geometry to Nanite, et voila! With a bit of Lumen magic, I'm running this at 50-60FPS at 2K, on my RTX 3070, in the day scene without DLSS (to maintain sharpness). When I go to night, and turn on the lights, it slows down considerably, so I enable DLSS to improve the graphics.
Sound is binaural when close to the trees, and there's a general open space ambience running. Love the photorealistic floor and pots from megascans.
Hope you enjoy this architecture tech demo in Unreal Engine 5!
