Steam Database has listed a next-gen version of Doom Eternal which could suggest that an upgrade is coming for the game on PC or consoles.
Bethesda Softworks is teasing something for DOOM Eternal on PC. This is related to the Nvidia Computex event. The teaser suggests that the developers might be working on a potential DLSS or RTX version of the game on PC. Since Nvidia is holding the Computex event soon, we might be able to get an idea of what they are teasing for DOOM Eternal.
More importantly, there is also a listing for a next-gen version of the game on Steam Database. There are two separate listings, one is for next-gen smoke, and the other is a simple QA branch for the next-gen version. While it is hard to know what exactly the developers are planning to do with these new updated versions, they did confirm last year that DOOM Eternal would get an update for PS5 and Xbox Series X.
After the release of The Ancient Gods Part 2, the developers don’t really have any updated roadmap for the future of the game. Their next update could arrive for the PS5 and Xbox Series versions while the PC version could also get an update for DLSS and ray-tracing support.
The game already runs at 4K at 60 FPS on the PS5 and Xbox Series X through backward compatibility mode. While the resolution is dynamic, it mostly sticks to the target 4K on the current-generation consoles. If there is an updated version, it has to be more than a resolution upgrade, possibly ray-tracing or 120 FPS support among other additions.
