Your PC will need a graphics card thats as powerful as a GeForce GTS 250/Radeon HD 6670 and it should be paired with either a Athlon II X2 270/Core 2 Duo E7600 3.06GHz CPU to match the Rooks Keep recommended system specs. This PC setup will deliver 60 Frames Per Second on High graphics settings on 1080p monitor resolution. You should also have 2 GB system memory for min specs. Another thing to consider is the DirectX capability of your GPU. Rooks Keep needs a GPU capable of running DirectX 10. To summarise, Rooks Keep needs around a 12 year old PC to play at recommended settings.
