The sticky "Updating Mobility drivers"...have you read it? If you have switchable graphics, ie, Intel and AMD the only drivers that will work on your computer has to come from Dell. Go to Dell and get the drivers. You cannot use the generic drivers that AMD offers. The games you mentioned can cripple computers with much higher specs than your laptop, so don't expect much.
You could try the Leshcat modded drivers...a link to which is in a post here.
