Bethesda and id Software are looking to deliver a smooth gore-happy experience to Xbox One X and PlayStation 4 Pro as Rage 2 will run at 1080p / 60 FPS on the consoles instead of supporting the eye candy that comes with 4K resolution.
Rage 2 will have high octane brutal action as seen in the trailers and it's not hard to see how 30 FPS would hamper the experience instead of playing it on a smoother frame rate. Bethesda and id Software are seemingly aware of this and they decided to forego 4K resolution on consoles in favour of better performance.
Tim Willits, the studio director at id Software confirmed this in an interview with Hardcore Gamer, as he stated that the game will run at 60 FPS on enhanced consoles, due to the decision to go for speed instead of 4K. The standard consoles will still be capped at 30 FPS.
Meanwhile, the PC version of the game will be uncapped so depending on a player's hardware, they will be able to run the game in 4K at 60 FPS or even higher as Willits didn't mention any frame rate caps. There is currently no available gameplay on either Xbox One X or PlayStation 4 but the graphics quality is unlikely to meet that of PC gameplay shown so far, as developers prefer to initially show their product in the best possible light.
When asked about potential post-launch content, Willits stated that there are plans for it but nothing is final yet. One interesting takeaway from his answer is that id Software planned for both paid and free post-launch content but it remains to be seen whether he simply talked about potential updates as the free part.
Rage 2 is so far looking a lot like DOOM but in a post-apocalyptic setting that was caused by an asteroid hitting the planet and not a demonic invasion from hell itself. The game is due for release on 14 May 2019 and it will release simultaneously on PC, PlayStation 4 and Xbox One.
