But when actually playing the game it runs so slow. Almost like frame by frame. The audio is fine and clear but the game is not. I have tried turning down the graphics and have tried deleting games i don't need off of my computer but still no better. Do i need more RAM? If so, how does that work, do i just go and buy it? Also, i have heard there is software that fixes drives and helps speed of computer, is it a free download? I need help urgently! I don't want my $60.00 game to go to waste. ANSWERS WOULD BE AWESOME
