Cities Skylines 2 has received its second optimisation patch

Expect a performance boost from Cities Skylines 2’s newest update

Colossal Order has released patch 1.0.12f1 for Cities Skylines 2, aiming to add further optimisation to the game on PC and address some simulation bugs. This update is now available to gamers on Steam, and the studio is working to deliver this patch to gamers on the Microsoft Store and PC Game Pass soon.

Cities Skylines 2 is a hugely demanding game on PC, and Colossal Order hopes to increase the performance of their game with future updates. At the start of the game’s lifespan, Colossal Order has focused more on gameplay than performance. This is why the game has received a “mixed” review rating on Steam despite the game’s performance issues. For every complaint about performance, there is praise for moving the city builder genre forward.

With update 1.0.12f1, Cities Skylines 2 contains a large number of new game optimisations. This includes optimisations for area lights, changes to shadow LOD calculations, changes to the rendering of small and large objects, and reductions to the unnecessarily large texture resolutions of some characters. These changes are all designed to increase game performance and decrease both CPU and GPU load.

With this new update, Cities Skylines 2 has also had a radio ad removed from “Spasm Radio” due to “offensive content”. Changes to a variety of simulation factors have also been altered to improve the game. Players using existing save files will need to run the game for a while before these simulation changes will have an impact.
