your wasting your time they only emulate SM2 so your framerates will never be playbale... the apps you want only work if your just under the requirments for the game but if your pc cant handle SM2 then your way below the requirments for fifa 12... and you will never get it to run at a playable rate. so just forget about it or upgrade.
oH! and dont bump your own posts. if you dont get an answer straight away...
anyways feel free to post your specs ... im sure the guys here will give you some recommendations on games which your kit can actually handle...
