Default [Q] Graphics are low. games look better on note 2 than note 3?

Hey guys. I noticed that wild blood game graphics are better on note ditto rom v3 than a stock note 3. How can i enable high quality graphics? Thanks in advance..

Edit:

I noticed that in asphalt 8 high and very high graphic options are greyed out. Not selectable too. I think Note 3 has a good gpu why can't i use high graphics in any game?
