Assassin’s Creed IV Black Flag System Requirements

If your PC meets the minimum requirements (Intel Core2Quad Q8400 or AMD Athlon II X4 620, Nvidia GeForce GTX 260 or AMD Radeon HD 4870, and 2GB RAM), you should be able to run the game at lower settings and resolution. Performance may vary.

At a minimum, you'll need an Nvidia GeForce GTX 260 or an AMD Radeon HD 4870 (with 512MB VRAM and Shader Model 4.0). For better performance, an Nvidia GeForce GTX 470 or AMD Radeon HD 5850 (with 1024MB VRAM and Shader Model 5.0) is recommended.

The game requires a minimum of 2GB of RAM to run. However, 4GB of RAM is recommended for a smoother and more stable experience, especially at higher settings.

It's unlikely. The game requires a dedicated graphics card with at least 512MB of VRAM. Integrated graphics solutions generally don't meet these requirements and may result in very poor or unplayable performance.

The best settings depend on your hardware. If you meet the recommended specs, try 'High' settings. If you meet only the minimum, start with 'Low' and gradually increase settings until you find a balance between visual quality and performance. Disable Anti-Aliasing for better performance.
