Today, Epic Games revealed its next-gen game engine, Unreal Engine 5. To showcase the power of its new engine, Epic revealed a brand new, fully playable tech demo that’s running on the PlayStation 5 in real-time. IGN asked what advancements are in the PS5 that allows for Unreal Engine 5 to function at this high of a level on the console. Epic founder and CEO Tim Sweeney explained that it was the system storage advancements Sony hardware architect Mark Cerny revealed earlier this year that makes the next-gen Sony console a powerhouse. [ignvideo url="https://www.ign.com/videos/2020/05/13/ps5-unreal-engine-5-tech-demo"] “I think, first of all, Sony has a massive, massive increase in graphics performance compared to previous generations. But you know, I guess we get that every generation?” Sweeney joked. “But Sony’s made another breakthrough that in many ways is more fundamental, which is a multi-order magnitude increase in storage bandwidth and reduction in storage latency.” As revealed back in March – in a digital deep dive on the PS5 hosted by Sony architect Mark Cerny – Sony revealed its custom solid-state drive that targets at least 5GB per second in terms of bandwidth. That’s compared to the 50-100 MB/s capable on the current PS4 hard drives. “[The PS5] puts a vast amount of flash memory very, very close to the processor,” says Sweeney. “So much that it really fundamentally changes the trade-offs that games can make and stream in. And that’s absolutely critical to this kind of demo,” Sweeney explained. “This is not just a whole lot of polygons and memory. It’s also a lot of polygons being loaded every frame as you walk around through the environment and this sort of detail you don’t see in the world would absolutely not be possible at any scale without these breakthroughs that Sony’s made.” [widget path="global/article/imagegallery" parameters="albumSlug=unreal-engine-5-playstation-5-tech-demo&captions=true"] Sweeney says that Sony’s storage architecture is far ahead of “the best SSD solution you can buy on PC today. And so it’s really exciting to be seeing the console market push forward the high-end PC market in this way.” While Epic wouldn’t comment on any potential performance differences between the PS5 and Xbox Series X, Sweeney confirmed that the features shown today, like real-time global illumination and virtualized geometry, are “going to work on all the next-generation consoles.” For more, check out IGN’s comparison of the PS5 and Xbox Series X.
