Citalis requires at least a Radeon R7 250 v2 2GB or GeForce GT 640 v3 to meet recommended requirements running on high graphics setting, with 1080p resolution. This hardware should achieve 60FPS. 4 GB will also be needed to achieve the Citalis rec specs and get 60FPS. Make sure your GPU can run DirectX 9 or Citalis won’t run. We suggest a 8 year old PC to play smoothly.
