Your PC will need a graphics card thats as powerful as a GeForce 9800 GT/Radeon HD 4850 and it should be paired with either a Athlon 64 X2 Dual Core 4000+/Core 2 Duo T6400 2.00GHz CPU to match the Serious Sam: The First Encounter 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 Serious Sam: The First Encounter rec specs and get 60FPS. Your graphics card will need to be capable of running DirectX 9. We suggest a 12 year old PC to play smoothly.
