Because it’s always fun to stoke the flames of the PS4 vs Xbox One debate, Digital Foundry has analyzed the recent high-resolution patch pushed to Doom, allowing it to take full advantage of the Xbox One X and PS4 Pro. The verdict? Xbox One X barely gets to 4K, while the PS4 Pro doesn’t come close.

According to the analysis, the Xbox One X is able to achieve native 3,840 x 2,160 Ultra HD 4K resolution in ‘select circumstances.’ Otherwise, the game uses dynamic resolution, which reduces or increases pixels produced according to demands of the game scenario to maintain as close to 60 frames per second (fps) performance as possible.
