XBOX官方：Coalition参与了Matrix demo的XBOX版内存和性能优化

所以有没有人能说一下ps5怎么做的优化？还是啥都没做，硬怼？

木桶原理，并不能只看最突出的一块儿。

个人理解，这个demo5给ps5制作后，移植给xsx的，对于ps5，整个程序设计是高度匹配，照着硬件写的程序和优化的程序，后者不是量身定做，
这也说明，游戏机这种照着硬件做的游戏，有超高的稳定性是适配性。

ps5要是有参与优化，早都被挖出来了，地表最强，能受这委屈？

The team had a CPU, Graphics and performance budget when making the Experience. For example, when the CG characters are on white, there is no background and so that “allowed me to use more Ray-traced area lights,” Pete recalls. “Whereas when we got into the car, we had to budget for the complex background, so I had to use less lights.” When the project first came together it only ran at 15 fps but as things were optimized the frame rate rapidly shot up. “But when we started everything was way over budget, we used a lot of 4K textures, a lot of geometry, Lumen, – which had a cost of its own, a new shadow maps technique for the sunlight – originally we were basically pushing the limits of everything.” The final experience however is indicative of what is possible for a game, running on a PS5 or XBox Series X/S there is still a lot of CPU headroom that would allow a game designer to run the normal mechanics of a game. The team did not want to build a demo that was unrealistic for what a new AAA game would be able to achieve.

看最后两句，无论在PS5或XSX上，CPU依然有大量余力做其他部分开发。只能说明XSX的架构确实不如PS5高效，导致理论上无比强悍的GPU发挥不出来。。。太可惜了。

其实现在xsx的问题还不是非对称内存导致的，应该说现阶段还体现不出这个劣势，最大的问题还是固定频率导致能效比不能完全发挥。

刚开发的时候PS5和XSX都是15帧。。。。。之后EPIC做了大量工作，优化了两台主机的表现。

估计XSX和XSS的内存架构有问题，不得不让参与开发的齿轮组加大力度深度优化。

PS：这样看来，绝对不是什么基于PS5开发，然后移植给XSX。

没游戏的下半年明显憋了很久终于找到黑点，还是熟悉的几位。建议贴吧再开几帖影响更大，这里人太少 ...

XBOX玩家又是光环无限，又是地平线5这么多游戏玩还不是有时间发帖证明PS5   LOW，结果被秒打脸。

PS玩家没游戏玩回应两句怎么了？

其实就是Epic基于两台主机开发，而微软额外派了战争机器组去协同优化XSX。
说什么基于PS5再移植，真以为开发者是傻、逼啊，完全就是某些人强行臆想，不愿接受罢了
毕竟XSX落后这一年已经听过108个版本的借口臆想了，永远立于不败之地

如果不是XSX一直和PS5数毛打的有来有回不分胜负，我还真可能信他们的说法了
