It was only yesterday that we reported that Assassin's Creed Valhalla couldn't reach 4K 60FPS on some of the fastest hardware on the planet... yeah well, it does, I just did it myself.
I've just run Assassin's Creed Valhalla's built-in benchmark with the Ultra preset at 4K and reached 62FPS on the Intel Core i9-10900K processor and MSI GeForce RTX 3090 GAMING X TRIO graphics card. The previous reports were from GameGPU that couldn't reach 60FPS at 4K, and were hitting just 56FPS average.
I'll be running all of the cards I have here (including some other Big Cards that may or may not have just arrived) with Assassin's Creed Valhalla and will have a deeper dive into the performance at 1080p, 1440p, and 4K in the next few days.
For now, Assassin's Creed Valhalla + Intel Core i9-10900K + GeForce RTX 3090 + Ultra = 4K 60FPS.
