If you're asking if more games/programs installed on your computer will slow it down, yes and no. If the hard drive gets nearly full, then it will start to slow down slightly because of the severely shrinking amount of free space. But, if you have a decent amount left, more than say 5 or 10%, then no, it shouldn't.
