As far as I can tell from what I noticed trying both:What features is the Game Pass version lacking compared to the Steam release?
- DLSS, which makes a BIG difference in performance. I went from a bit of a choppy start on my 2070 Super on medium settings for the Game Pass version to pretty much a perfect framerate on high with DLSS Performance mode.
- Dedicated Server options
- General balancing. In the Xbox client, some recipes are on different tiers, the quest requirements (basically a guiding hand telling you what to aim for building) are different, and if I remember correctly, the updated client on Steam lets you craft 3 arrows at a time vs the Xbox version only crafting 1.
I didn't get far into the Xbox version before deciding to switch to Steam. Decided pretty quickly that it was worth the £20 and didn't want to commit to playing an out of date version.
