Playing in windowed mode at double size to resolution [solved]

[Bobsy]

This is one of those questions that will almost certainly be so obviously easy I look like a complete idiot, or so obviously impossible I look utterly naive. Well, yeah. Such is life.

My aim is to have a game suited for running in windowed mode at 320*240. Except that's stupid-tiny on modern machines and I don't want players to have to squint. So... what I'm after is for a 320*240 res game to display at double-size, or possibly triple-size. For a nice pixel-art visual style.

I know one solution would be to make the entire game at 640*480 and double the size of all artwork, but that doesn't seem, y'know, right. What I'm after is for the game window to be at double size. Possible? Not possible?

Am I making any sense?

Just use the 2X/3X filter in the game's setup.

As easy as that! Yes, it was the former of my two options.

Muchos gracias, senor.
