I'm making a mode7 game like mario-kart and I need to tilt the image before I draw it, I have tried using a buffer canvas to tilt the image then draw it on the games canvas but this makes it laggy (because the image of map is 1280 x 2556.)

So my two questions are:

How did the tilt images in the original mario-kart

How can I tilt my image like they did in mario-kart
