This is a 2012 game and your pc is a little bit of outdated. http://www.game-debate.com/games/index.php?g_id=983&gam...
Shader model 3.0 is hardware inside the graphics card. Your PC is really old and sol is your graphics card. I believe graphic cards with SM 3.0 were released back in 2004.
Unfortunately your PC is really too old to play games released in the past 5+ years. Much has change in the past 10+ years. If you want to spend as little money as possible, then I simply recommend you do not play the game, that way you spend $0.
If you want to play that game then you need to buy a new computer.
