After the presentation of Unreal Engine 5 on PlayStation 5 (we reported; Demo video see below) the question arose whether current PC systems could handle this playable real-time demo. The answer is not surprising: Yes, but the hardware requirements are not without, especially on the graphics card (GPU: graphics processor) and memory architecture and the memory bandwidth would be important.
Tim Sweeney (head of Epic Games): “To display this level of detail, a number of different components are required. One of them is the GPU performance and the GPU architecture to draw an incredibly large number of geometric objects a very large number of teraflops that are required for this. The other is the ability to load and stream them efficiently. ”
“Would this demo run on a PC with an Nvidia RTX 2070 Super?” Kim Libreri (Epic Games Chief Technical Officer) answered this question PC gamers with a clear “yes”. He even said that you would get a “pretty good” performance with this graphics card. The graphics processor of the PlayStation 5 reaches approximately 10.28 teraflops. The computing power of the RTX 2070 Super is slightly more than 9 teraflops, whereby it should be noted that the pure computing power is influenced by other system aspects – e.g. the storage architecture so that the data can be supplied “quickly” enough. And the PlayStation 5 is specially tailored to this “data spinning requirement”.
Currently at reference Sweeney said of the loading and streaming of data / textures / models that the SSD architecture of the PlayStation 5 was “divine” and “fairly far ahead” of the PCs. It is the best storage technology across all platforms. That’s why Mark Cerny related to the late PS5-GDC presentation also so much time to present this powerful architecture. Sweeney still believes that with an NVMe SSD in a PC, you could still achieve “fantastic performance” in this area. In any case, the Epic Games boss believes that games will no longer be loaded from a normal hard drive (SATA-HDD) in the future.
Sweeney: “One of the great efforts that have been made with Unreal Engine 5 and continues to be is to optimize for next-generation storage to speed up loading times more than current performance. Not only a little bit faster, but a lot faster, so this geometry [bzw. komplexe 3D-Objekte] can be integrated and displayed even though it does not fit completely into the video memory. “He also said that pop-ups or fade-ins of objects are virtually history thanks to the new technologies.
Although Unreal Engine 4.25 already offers real-time ray tracing support via Microsoft DirectX Raytracing (DXR), ray tracing was not an issue at yesterday’s presentation. Most likely, Sony and AMD (chip manufacturer) weren’t ready to present the hardware features and software interface to the public, with a spokesman for AMD Reddit clarified that “no hardware vendor-specific ‘proprietary’ ray tracing technology or other GPU features should slow down and hinder the game industry introducing next-gen features. With this console dynamics and Microsoft’s DXR for PCs, I hope that we can work towards an open ecosystem for all games and gamers, “said Scott Herkelman (VP & GM Radeon Business Unit at AMD).
Phil Spencer, Xbox boss at Microsoft, also signed up GameSpot spoke up, praised Epic Games ‘work on the Unreal Engine 5 and said that “many” of the Xbox Game Studios’ internal teams would use the Unreal Engine, although he did not specifically name the Unreal Engine 5. He only became more specific in one example. Microsoft is “enthusiastic” that they can use the innovations of Unreal Engine 5 in Senua’s Saga: Hellblade 2 on Xbox Series X. Xbox Marketing boss Aaron Greenberg can already imagine what the new Unreal Engine 5 will look like “on the most powerful console in the world”.
