Good question. I'm the wrong person to comment but i will still comment hahaha. I don't play games. But the question also is what is your game(s)? Does your game requires high end GPU (graphics) and match with high processing CPU?
MiA1 uses Snapdragon 625 which is basic for playing average hardcore games. If you play NBA, you might notice lags (this id based from the blogs I read).
So better check the requirements of your games first if it requires Snapdragon higher than 625. I can sense that you may play car racing like a Ferrari racer? It may lag but go to youtube for game reviews for MiA1.
