I have no idea about graphics ect, I'm worried about sims 4 not running on my laptop. This may be a stupid question, but the CAS demo works fine would that mean the game will be okay? I have Sims 3 and all the expansions bar supernatual currently on my laptop. I cant have the graphics super high and it lags slightly running sims 3 but nothing that really affects the gameplay. Any advice would be much appreciated.
