Stellaris Update 3.10.3 Pyxis Released With Stability Fixes and Beta Preview

Paradox Interactive has released Stellaris update 3.10.3 Pyxis, focusing on stability and bug fixes. The update also previews a holiday open beta targeting research speed power creep and ship cost reductions.

Stellaris update 3.10.3 Pyxis is live, bringing stability fixes from the recent open beta alongside a preview of upcoming economic balance changes.

Pyxis Bug Fixes and Improvements

The Pyxis update clears outliner notifications correctly when using keyboard shortcuts, assigns Ulastar as an advisor, and makes Vas the Gilded an ambassador. Pre-FTLs in Federation's End have their technological progress frozen, and a startup crash for Linux and the Steam Deck has been resolved.

Holiday Open Beta and Research Changes

A holiday open beta running through mid-January will test balance adjustments aimed at curbing technology power creep. Research speed bonuses will now generally come with increased researcher upkeep as throughput bonuses. Breakthrough technologies will replace standard 20% research field techs, gating progress and becoming cheaper as more known empires research them.

Economy and Ship Cost Reductions

The holiday test branch also scales back researcher job output, halves the effectiveness of the Ministry of Science, and replaces or removes most sources of ship build cost and upkeep reductions from traits, civics, traditions, and agendas.

Why this patch matters

Update 3.10.3 delivers stability fixes while signaling an upcoming shift in Stellaris balance to rein in late-game power creep.
