Just a quick question

What is texture scaling?

What happens if I change the level to 2x or 3x?

You get a better texture effect.. ie: say you playing a game and certain round objects are squared and pixelated etc, 3x will give a more polished look(less pixels).
PS: may slow gameplay down... not sure.
