Quick and dirty grass shader

I would love to try out a copy, is it really performance heavy, I have had to use a macbook pro laptop to do my arch viz stuff on cause I graduated college last year and have been working with the state to find a job for an entire year so I havent had the opportunity to buy a good desktop computer. If it helps here are my specs for my Macbook and my email is josephlemons69@gmail.com if you want to send me a copy.
