DOOM finally received its ‘4K patch’ for Sony’s PlayStation 4 Pro and Microsoft’s Xbox One X. However, early tests from YouTuber VGTech indicate that 4K resolution is never really achieved on the PlayStation 4 Pro, whose maximum resolution is 1440p with vertical dynamic scaling taking place during the more demanding scenes.

On the other hand, the Xbox One X does reach actual native 4K (3840×2160) resolution but often drops below that. Here’s what VGTech had to say about both tests:

The PS4 Pro version uses a dynamic resolution with pixel counts ranging between 2133×1440 and 2560×1440. The most common resolution on PS4 Pro seems to be 2560×1440, but the resolution is often below this figure during demanding scenes. The PS4 Pro does downsample when outputting at 1080p.

The Xbox One X version uses a dynamic resolution with pixel counts ranging between 2688×1512 and 3840×2160. The Xbox One X rarely reaches a resolution of 3840×2160. The resolution on the Xbox One X varies a lot so it is difficult to get an average figure, but a common range during demanding scenes seems to be between 2688×1512 and 3072×2160.

This lines up with the early assessment made by NXGamer, another YouTuber who regularly takes upon himself to compare enhanced PlayStation 4 Pro and Xbox One X updates.

The average frame rate seems to be 57.8 FPS on PlayStation 4 Pro and 59.16 FPS on Xbox One X. In both cases, PlayStation 4 Pro and Xbox One X ran at a higher frame rate when unpatched, though obviously at 1080p resolution.

As a reminder, 2016’s DOOM runs on the id Tech 6 engine (just like Wolfenstein II: The New Colossus).
