struggling on graphics for pvz bfn.

@AkhiroChoi Hello! As far as I can see, you already posted about this in the technical problems forum. If you take a look at the replies there, you will see that an EA community manager (EA_Illium) replied there. Judging by the image, you are using Intel integrated graphics, which are known not to be very good.
You can check out the requirements to run the game here: https://www.origin.com/irl/en-us/store/plants-vs-zombies/pvz-battle-for-neighborville#store-page-section-description
