FAQ
Can the 8 GB iMac M3 run Cities: Skylines?
Yes. With 8 GB we estimate 68 FPS at 1080p High.
Can Cities: Skylines hit 60 FPS on the iMac M3?
Yes: at 1440p Low it runs around 60 FPS.
What about 1440p and 4K?
On High, the iMac M3 gets about 43 FPS at 1440p and about 22 FPS at 4K in Cities: Skylines. These are native figures.
Do these figures include MetalFX or ray tracing?
No. The headline figure is native resolution, no MetalFX and no ray tracing. Cities: Skylines has no MetalFX on Mac. Ray tracing, where a game offers it, costs a lot of FPS on any Mac.

Not quite: it has an official macOS version, but built for Intel. On Apple Silicon it runs through Rosetta 2, built into macOS, with nothing else to install. Our figures already include that overhead.
