Your PC will need a graphics card thats as powerful as a GeForce GT 740 v2 EVGA FTW 2GB Edition/Radeon R7 250X and it should be paired with either a Phenom II X4 965/Core i5-750S 2.4GHz CPU to match the ROKH recommended system specs. This PC setup will deliver 60 Frames Per Second on High graphics settings on 1080p monitor resolution. ROKH needs a Core i3-2115C 2.0GHz or Athlon II X3 455 processor coupled with a GeForce GT 720 v2 to get it to run minimum system requirements. This will return around 30FPS at 720p screen res on low graphics settings, but you can also adjust the settings further to tweak. You should also have 4 GB system memory for min specs. Another thing to consider is the DirectX capability of your GPU. ROKH needs a GPU capable of running DirectX 10. In short you need a 6 year old PC for best ROKH performance.
