新闻源:https://www.bilibili.com/video/BV1kK411W7fK 虚幻引擎官方直播 5.14 (ue5首次直播)
时间点:52分:57秒
Our goal is that the graphic quality like this demo, we want to make it run 60FPS at next-gen consoles. But now we do not reach the goal. Now it is 30FPS. Our target is 60FPS, that is also why we can not release it now. And I can ensure that we can run this demo in our notebook, in editor , not cooked, it even can 40FPS. ( After someone in BBS confirm that the device is RTX2080 and 970EVO )
SSD speed like PS5 is helpful, especially those huge scene streaming. Nanite and Virtual Texture is depend on I/O. Do we need such fast SSD so that we can run that demo? In fact if we analyze that, for example 2K. Our finally goal is that each pixel with one triangle. I assume with two triangle. In fact there are not such many triangles. It means it is MB/S level. It doesn't need such fast SSD like PS5 to run the demo.

根据Epic Games中国直播中的的消息称:一台搭载RTX 2080移动显卡的笔记本运行虚幻5 Demo的帧数更快,能达到1440P/40fps。
直播中Epic官方确认,对于虚幻5 Demo,他们在次世代主机上的目标是60帧,但现在还达不到这个目标,目前只是30帧。此外他还确认他们能在他们的笔记本运行这个Demo,在编辑器中达到40FPS(后来有人在论坛上确认这个笔记本的配置是RTX 2080和970EVO)
看起来这个虚幻5技术Demo并没有充分利用PS5的超快SSD。毕竟笔记本搭载的NVMe 970SSD便足够让这个Demo达到1440P/40fps。
