After a few hours of playing civ 4 warlords, my MBP was extremely hot and suddenly, the cities and resource locations turned black while the rest of the game played on fine. My friend who gave me the game told me that it was a problem of my graphics card and the game would be playable once my comp cooled. Now I don't know if games generally **** up like that or no but I would like to know whether it is a problem with the game or the MBP or if it is no problem, just a way of life. I also play an emulater on my comp (pokemon fire red cause that's what all uni students do right? ) and it gets to about 80 degrees celius really quick. Should I be worried or no? Finally, should I install fancontrol if I am doing things like that on my MBP?
