Installation is straightforward via digital platforms like Origin or physical discs. Always update your graphics drivers and run the game in compatibility mode if needed for Windows 10 or later.

Minimum and Recommended Specs

Minimum requirements include a 1.8 GHz Intel Core 2 Duo processor, 1.5 GB RAM (XP) or 2 GB (Vista/7), and a 128 MB video card with Pixel Shader 2.0 support. These specs allow basic gameplay but may struggle with large neighborhoods.

Recommended specs feature a 2.0 GHz dual-core processor or better, 4 GB RAM, and a 256 MB video card like NVIDIA GeForce 6600 or ATI Radeon X1300. For optimal performance with high settings and mods, aim for an Intel i5 or equivalent with 8 GB RAM and a dedicated GPU.

Installation Tips and Troubleshooting

Run as administrator and apply the official 1.69 patch for stability. Mod users should install NRaas Overwatch for auto-fixes.
