Cities Skylines modding setup in South Africa

Quick Answer

A modded Cities Skylines setup (especially Cities Skylines II or a heavy CS1 list with Network Extensions and TM:PE) wants a fast CPU, 32GB DDR5-6000, and a 1TB NVMe. A build around R18,000-R22,000 at Evetech keeps a large modded city smooth, since CPU and RAM, not the GPU, decide simulation performance.

RAM, VRAM and Storage Explained for Modded Cities Skylines

Cities Skylines is simulation-heavy and asset-hungry. 32GB DDR5-6000 is strongly recommended once you load hundreds of assets and mods; 16GB stutters in big cities. VRAM of 8GB-12GB handles the asset detail, but the real constraint is CPU for the traffic and agent simulation. A 1TB NVMe matters because the game streams a huge asset library and a slow drive causes long load times and hitches in dense metropolises. A 1TB NVMe SSD is the single most cost-effective addition here, cutting load stutter that even strong CPUs and GPUs cannot mask.

A Sim-First SA Modding Build

Centre the build on a strong CPU like a Ryzen 7 9700X or 9800X3D with 32GB DDR5-6000 and a 1TB NVMe, plus an RTX 5060 Ti or RX 9060 (around R10,000-R13,000). That combination keeps a large modded city's traffic and agents simulating smoothly. Prioritise CPU, RAM and storage over the GPU, since the simulation, not the visuals, is what stutters in a big modded build.

FAQ

How much RAM does modded Cities Skylines need?

32GB DDR5-6000 once you load hundreds of assets and mods. 16GB is the floor but stutters in large cities with heavy mod lists.

Is Cities Skylines CPU or GPU heavy?

CPU heavy. The traffic and agent simulation is the main load, so a fast chip matters more than the GPU for smoothness in big modded cities.

Does an SSD help modded Cities Skylines?

Yes. A 1TB NVMe streams the large asset library fast and cuts the load times and hitches a slow drive causes in dense modded cities.
