I'm not really asking for fullscreen in a sense. I've made the mistake of creating a game at [1024,768] size with huge textures and now after compressing them with things like tinypng, adding culling etc (trying to make my game as efficient as i can) I'm still not happy with its performance which is obviously the result of texture size (things like [3000,768] per texture) So here's my issue it would be great to hear your opinions: I require (if possible) the game to be running at [1024,768] so would simply setting the pixi canvas to something like [640,480] (still 4:3), resizing all my textures to fit in 640 480 and scaling the screen through html be more efficient than what I have now? Would it still look anywhere near as good? If else then is there a way I can adjust the size of my game to the browsers fullscreen while maintaining my desired aspect ratio? I'm fairly new to html5 development so any and all feedback is appreciated thanks.
