Not long ago, PS5 released a technical demo of Unreal Engine 5, which demonstrated the powerful performance of the next-generation host in terms of picture quality performance. Some of the details have a crushing advantage over this generation of PS4 hosts. Foreign media gamingbolt summarized the major upgrades of the 5-point PS5 console in terms of picture quality, which are completely impossible for PS4.
PS5 vs. PS4: 5 major improvements
1. PS5 vs. PS4: The number of super high polygons
The most obvious progress in the presentation is the super high quality of geometric figures and object materials. All objects, including small fragments, are rendered with high quality, and no tricks such as normal mapping are used. Although PS4 also has a higher number of polygons than the previous generation host, which can draw more than 11 million polygons on the same screen, its original polygon throughput bottleneck is not enough, and LOD (multiple levels of detail) distortion is serious at long distances.
The PS5 host has increased the original computing throughput by 5 times, which enables the Unreal 5 Nanite virtual micro-polygon technology, which can truly render all objects in the field of view in real time, and each rendered polygon is visible to the naked eye. The highest fidelity, the amount of detail displayed at close range is amazing, and it can even show every hair of the human body.
2. PS5 vs. PS4: Long-distance LOD also has high quality
Many games of this generation have objects popping up at medium and long distances, and PS5 can avoid this. Polygons are rendered at the pixel level, so objects at long distances can also be the highest Quality display without losing detailed information. In particular, PS5 has an ultra-fast SSD storage architecture, which means that there will be no sudden emergence at all.
3. PS5 vs. PS4: Real-time global illumination solution
The new Lumen global illumination system is also a major focus in the demonstration, which is one generation ahead of the current baked global illumination, and can achieve a similar real-time light tracking effect without hardware support. Although the final effect may not be as strong as RTX, it is enough to be called the "next generation". If the Lumen technology is used in this generation of hosts, it is necessary to make many compromises, such as reducing the number of lights and reducing the indirect lighting effect.
4. PS5 vs. PS4: Large memory and 8K ultra-clear material
The demo demo includes not only high-fidelity geometric figures, but also ultra-clear 8K materials to ensure that the objects have high-definition details when viewed at close range; Nanite can directly import photo-grade materials and models to show extremely realistic pictures. This is mainly due to the increase of PS5 system memory, PS5's 16 GB large memory pool is twice that of PS4, and ultra-fast SSD storage is even faster than some RAM, and material resolution is no longer a bottleneck .
5. PS5 vs. PS4: The micro-physics system makes the interactivity greatly upgraded
There is a detail that is easy to miss in the demo video: when the protagonist jumps on the edge of a cliff, 3D geometric fragments are splashed under his feet. In this generation of hosts, such small objects are generally approximated by low-quality particle effects, or a fragment simulation effect is triggered when moving.
The Nvidia PhysX system can also be used on the PC to simulate the movement of a large number of small fragments, and this aspect has not been paid much attention to on the host computer. On the PS5, the powerful CPU and GPU computing power is used to directly simulate the small pieces that can be moved according to physical laws and built with Nanite, which greatly enhances the interactivity and authenticity.
