I know that scaling your game is best done with the Ultimate Full screen object, but I'm wanting to know if this is the best method for scaling your game, that uses HD graphics.
Basically I'm creating a game at 1920 x 1080 and I want to make sure the game scales down and up to other resolutions correctly. Obviously it'll need to use letter boxing for different aspect ratios, such as 4:3 and 16:10. I heard that Fusion 2.5 prefers to scale graphics up rather than down, but that sounds the opposite from what I've always known and done, as scaling up reduces quality. So before I go too far I want to confirm what approach would be best. Should I design the game at 1920 x 1080 like I'm doing, or design at a different resolution?
Oh another little question. The game has no scrolling in it, the playing field is the size of the screen. This shouldn't have performance issues with sprites designed at that screen size should it? I'm also trying to keep to power of 2 sizes.
Thanks.
