Atlas Reactor requires at least a Radeon HD 7850 or GeForce GTX 750 Ti to meet recommended requirements running on high graphics setting, with 1080p resolution. This hardware should achieve 60FPS. 6 GB will also be needed to achieve the Atlas Reactor rec specs and get 60FPS. You will require a DirectX 9 GPU. We suggest a 6 year old PC to play smoothly.
