The Unreal Engine 5 tech demo looks pretty amazing, but it was supposedly run on a PlayStation 5, not a gaming PC. So what kind of PC do we need to get that kind of quality?
I couldn’t get any exact specifications from Epic, but on a conference call earlier this week I asked how an RTX 2070 Super would handle the demo, and Epic Games chief technical officer Kim Libreri said that it should be able to get “pretty good” performance. But aside from a fancy GPU, you’ll need some fast storage if you want to see the level of detail shown in the demo video.
Sony was heckled a bit for its focus on the PlayStation 5’s storage speed, and if all you’re imagining is loading screens disappearing more quickly, it does seem like an odd focus. But it’s about moving beyond loading screens entirely, to the point where “you can bring in [the demo’s] geometry and display it despite it not all fitting in memory,” says Epic CEO Tim Sweeney.
In other words, the storage needs to be fast enough to keep up with the player, allowing the game to seamlessly increase the complexity of distant objects as they get closer without ‘popping in’ more detailed models—something we’ve gotten used to seeing.
