The Xbox Series X has all the bells and whistles necessary to run modern-day AAA titles at 4K. Its 12 TFLOPS of computing power is up there with high-end graphics cards when it comes to raw power. Given that both platforms operate on entirely different architectures, it would be unfair to compare them based on that alone.
Assassin's Creed fans were left fuming on May 7th at Microsoft's Xbox Series X gameplay reveal. Not only did it reveal very little in the way of gameplay, but it also looked quite underwhelming. Now, it has come to light that Assassins Creed Valhalla will not be able to run at 4K 60FPS on the console, despite its apparent sacrifices in visual fidelity.
A Ubisoft spokesperson told Eurogamer.pt that Assassin's Creed Valhalla will run on the Xbox Series X at 'at least 30FPS.' The phrase, when translated to real-world speak, essentially means that the game will have a hard time hitting the 60fps mark. The 4K 60FPS barrier is quite an important one to break for consoles, and Assassins Creed fans might have to wait a bit longer before they can experience it.
It doesn't necessarily mean that the Xbox One Series X won't be able to pull off 4K 60FPS on other titles. It takes developers quite some time to squeeze the maximum performance out of a gaming console. We've seen this time and again with the PlayStation 3, PlayStation 4, Xbox One, and Xbox One X. Even if Assassin's Creed Valhalla doesn't break the 4K 60FPS barrier, one can rest easy knowing that there will be a dozen other titles that will.
