It was possible to use Quixel assets in UE4 as well. https://www.youtube.com/watch?v=9fC20NWhx4s https://www.youtube.com/watch?v=9fC20NWhx4s The assets used in the UE5 demo are available in Quixel's website. https://quixel.com/megascans/collections?category=environment&category=natural&category=limestone-quarry&size=size-gte-1-lt-2 https://quixel.com/megascans/collections?category=environmen... The 8K cinematic assets that Epic used in the demo are between 1 and 2MB in size. So I suspect it's more to do with PS5's SSD which has a bandwidth of more than 5GB/s and 16GB of GDDR6 RAM, which allows more textures to be streamed from the hard drive and held in the RAM. PS5's GPU supports raytracing, which Epic said they didn't use in the demo. So the dynamic lighting must be something new they've developed for UE5.
