I?m using the standard of 800x480. The scale letterbox will fit the project to 1280x720 and/or lower screens, this I understand.
But I?m talking about RE-sizing the project to different resolutions. Because I figure that if I run an 1280x720 project in an 800X480 cellphone, using letterbox option, the game will execute and adjust, but I assume that it will run substantially slow.
I thought we had to save different Capx adjusting project resolution and layout resolution and moving and scaling every sprite on the project.
