The description just said "4K" support with "dynamic resolution". Many gamers assumed this was a checkerboarded or upscaled solution like the 1440p 30 FPS target on PlayStation 4 Pro. However, that's not the case and the game manages to achieve native 4K almost all the time on Xbox One X. Even when it dynamically scales down the resolution to maintain 30 FPS, it only does so on the horizontal axis so the game looks crisp even during these drops.

Digital Foundry conducted a detailed analysis on Fallout 4 for Xbox One X today where they discovered that even during taxing moments the game only dropped down to 3264 by 2160 pixels. In comparison, native 4K is 3840 by 2160 pixels. This is orders of magnitude better than the target resolution of 1440p (2560 by 1440 pixels) on Sony's machine. This means that the Xbox One X version should look crisper on a 4K display. There are other enhancements like better lighting and god rays but they're similar across the Xbox One X and PlayStation 4 Pro.

It's great to see developers take advantage of the 1.8 teraflops difference between the two machines to push higher resolutions on Microsoft's device. Hopefully even more game makers will do this in the future as they become even more familiar with the console.

In Fallout 4, as the sole survivor of Vault 111, you enter a world destroyed by nuclear war. Every second is a fight for survival, and every choice is yours. Only you can rebuild and determine the fate of the Wasteland. Be sure to check out the game if you like open world shooters and role-playing titles.
