Cities: Skylines 2. Hugely problematic launch, but it runs acceptably for me on Linux (just over 40fps consistently on a Ryzen 5 7600X and a 6600 XT). I’ve got all settings on high (except Volumetric Quality set to Disabled and AA set to TAA) and it honestly looks quite good, especially with DOF set to tilt-shift.
In terms of the game itself, I’m very much enjoying it. Every mechanic seems more detailed than C:S1 and there is a lot more planning needed to make a really successful city. Not without bugs but nothing game breaking. Lacks some of the annoyances in the first game (like needing water pipes everywhere).
