Try this purely node-based shader for grass - based on something BB posted ages ago. It renders nice and fast and looks pretty good on just about everything I've used it on.

EDIT: my units are set to METRES in my prefs, so adjust the displacement value accordingly (in this example displacement is 2 inches).
