Hello everyone,
We are excited to share with you a preview of version 4.1.1. This is a focused follow-up to 4.1 aimed at late-game performance. The most noticeable change is reduced lag when ending a turn in a large, late-game empire. We have also fixed a handful of crashes and made it harder for rivals to culture-flip your planets. Please read below for details.

Steam

• Select Galactic Civilizations IV from your Steam Library list.

• Right-click and select "Properties."

• Select the BETAS tab.

• From the dropdown, select "Insider" and click Close. (If you don't see this option, restart Steam.)

• Steam should pull down the changed files; if you ever want to return, do the same as above but select "default."

Epic

• Open the Epic Launcher

• Select "Galactic Civilizations IV: Supernova - Insider's Edition"

• Install and play!
  

Please note: The opt-in (Insider Build) is an early preview of the next update, and you might experience bugs or other issues.

v4.1.1 Change Log

Engine

• Fixed late-game lag ending a turn in the late game due to stat calculations when colonies changing hands.

• Fixed late-game lag related to fleet range calculations.

• Colonies that lose their sponsor during a rebellion are no longer left stranded, and any stranded sponsor links in an existing save are repaired on load.

• Fixed a crash when mousing over the key terms in the Energy resource bar tooltip.

• Fixed a crash in multiplayer when a completed mission referred to an ship that was not in a fleet.

Gameplay

• Influence is now much stronger on a planet's own tile and the six around it. A planet is much harder to culture-flip unless the competing source is close by or vastly stronger. Borders elsewhere are unchanged, so empires still cover the map as before.
