Well, Atomic Heart hasn't done itself many favours in the run-up to its release. The game is only five weeks from its release and Xbox Game Pass arrival, and if it weren't for a few things, we'd know no better than to be incredibly excited.

After all, a Bioshock-esque game set in a utopian Soviet Union and scored by Mick Gordon sounds like an absolute treat. At least it did, until developers at Mundfish offered fans a divisive response to claims it has sympathies for Russia and their part in the ongoing invasion of Ukraine.

Failing to subdue worries of fans, Mundfish has now revealed the game's position when it comes to performance, and it's a little concerning.

Atomic Heart's Performance Will Depend On Where You Are

Apparently, the performance of Atomic Heart will depend on where in the game you are, with the open-world segments expected to run worse than in closed areas.

In response to one fan asking about the performance of the game, Mundfish's official Atomic Heart Twitter account responded by confirming the game will be reaching 4K and 60 fps in dungeons along with dynamic resolution. 

Elsewhere, it will be "mostly" 4K at 60 fps in the game's open world. It's a pretty alarmingly unconfident announcement, especially as it's just in response to a single fan - and the use of "mostly" is concerning.

We do see these dungeon-esque areas in some of the game's trailers, and it makes total sense that Atomic Heart should require more power for larger sections, but equally, the lack of confidence from Mundfish doesn't exactly inspire it in others.

When Is Atomic Heart Coming Out?

Though many have commented on the fact that now is a pretty touchy time to release a game set in the Soviet Union, it's right around the corner.

Atomic Heart is set to launch on February 23 and will be available on PC, Xbox Series X|S, Xbox One, PlayStation 5 and PlayStation 4. And, of course, it'll land on Game Pass on the very same day.

Fans are right to be concerned about the performance of the game, especially as this is a pretty massive debut for Mundfish. Here's hoping the team can pull through a banger.
