Patch 1.01.020 - Holiday Performance Update
KAISERPUNK Patch Notes — December 16, 2025
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.

Season’s greetings, Governors!
As mentioned in our latest dev log, we had one more update planned before the holidays - and here it is. While we continue work on the larger warfare updates, we’ve also managed to implement some significant optimizations. These should result in performance improvements across the board, with especially noticeable gains in larger cities and on higher-spec hardware. For players with lower spec hardware, the impact of lowering Texture Quality settings will now make a bigger difference and might also help prevent stability issues in some cases.
There are also a number of additional fixes and changes included in this patch. Notable highlights include a new infoview filter that highlights buildings' condition showing if it’s damaged - something that’s been widely requested by the community. We’ve also reduced deployment times for all military units, as well as decreased the cooldown for naval units by 50%.
Finally, we’ve added new layout options for all basic utility buildings. These allow you to change where the entrance is located within the 2×2 footprint, making it easier to fit them snugly into your sprawling cities.
As the holiday is upon us we’d like to wish you all a Merry Christmas and a Happy New Year. To celebrate a little extra we’ve created our very own rendition of Silent Night to get you all in the holiday spirit and give you an alternative to the written changelog.
We wish you all a happy Holiday!
