It is a UE5 game, so don’t expect it to run great. But it’s verified and the minimum specs requirements are in line with other high end titles that run acceptably on the deck.
Edit: performance first impressions from SteamDeckHQ. Sounds like it runs and a pretty consistent 30fps, with some small dips outside near large groups of people. Reviewer was using XESS upscaling on performance.
SteamDeckHQ did a first impressions, and they’re getting a pretty consistent 30fps (higher fps possible inside, but outside can’t go much higher than 30. They mentioned a few fps dips near crowds but that’s it.
It sounds like you’ve got a bad setting somewhere or something else going on, assuming their account is accurate.

I’ve done some more testing since my initial comment, and my experience is pretty much exactly as that article describes. Better than I had it before.
Overall it’s okay, but probably best experienced on a PC. Nice to have it nonetheless, and maybe it will get some updates to make it perform better!
