Frequently asked questions
What GPU do you need for Cities: Skylines 2?
Per Steam, the minimum is a GTX 970 4GB / RX 480 8GB and the recommended card is an RTX 3080 10GB / RX 6800 XT. It is genuinely GPU-heavy — even strong cards struggle at native 1440p and 4K, so many players rely on DLSS/FSR.
How much RAM does Cities: Skylines 2 need?
Steam lists 8 GB minimum and 16 GB recommended. Large cities benefit from 16 GB or more.
Why is Cities: Skylines 2 so demanding?
Unlike most city builders, it puts heavy load on the GPU, not just the CPU. It launched poorly optimized; patches have helped, but it still asks a lot of your graphics card above 1080p. Lowering a few settings or using upscaling helps a lot.
