Your PC will need a graphics card thats as powerful as a GeForce GT 230/Radeon HD 6550D and it should be paired with either a Athlon 64 X2 Dual Core 4000+/Core 2 Duo E4300 1.8GHz CPU to match the Shelter 3 recommended system specs. This PC setup will deliver 60 Frames Per Second on High graphics settings on 1080p monitor resolution. 2 GB will also be needed to achieve the Shelter 3 rec specs and get 60FPS. You should also have 1 GB system memory for min specs. You will require a DirectX 9.00 GPU. We suggest a 12 year old PC to play smoothly.
