To play this game what system requirement? It's too chopy in my system
Actually the game doesn't require anything fancy, but for Ultra setting in 1080x1920 resolution a better graphic card is recommended.
I have an Intel i5-4210M CPU (2.60GHz) with an onboard Intel HD graphic card and the game runs fine in "normal" graphics settings. However, you will experience game crashes and long transition time due to the game engine (Fungus) and bad coding. It is also recommend to stick very close to the Walkthrough to avoid crashes.
Another problem could be a bloated Windows system with not enough RAM. You can try to lower the graphic settings and switch to a lower resolution in window-mode.
