RollerCoaster Tycoon 3: Complete Edition System Requirements

If your PC meets the minimum requirements (Intel Pentium 4 2.0 GHz/AMD Athlon XP 2000+, NVIDIA GeForce 6200/ATI Radeon 9600 Pro, and 2GB RAM), you should be able to run the game, but likely at lower settings and resolutions. Expect performance issues with larger parks.

At a minimum, you'll need an NVIDIA GeForce 6200 or ATI Radeon 9600 Pro. For a smoother experience, especially with larger parks, an NVIDIA GeForce 8800 GT or ATI Radeon HD 4770 is recommended.

The game requires a minimum of 2GB of RAM. However, 4GB of RAM is recommended for better performance and stability, especially when building large and complex parks.

While technically possible if your integrated graphics meet the minimum GPU requirements (similar performance to GeForce 6200/Radeon 9600 Pro), performance will likely be poor, even at low settings. Dedicated graphics are highly recommended.

This depends on your hardware. If you meet the recommended specs, try high settings. If you're closer to the minimum, start with low settings and gradually increase them until you find a balance between visual quality and performance.
