- s-macke 12y agoDon't know. But here some possibilities: 1. No fullscreen 2. I update the screen only if a key is pressed.(No rain, that has to be rendered all the time) 3. I don't use any costly canvas functions. I render everything myself in a pixelbuffer. 4. Typed arrays
- hunterloftis 12y agoIt's #2. Redrawing at 60hz (or as close as the machine can come) is what hits the cpu so hard.
- s-macke 12y agoNo, I don't use requestAnimationFrame right now. I think when I wrote it, it was not supported by IE. But can't remember. I calculate as close as the machine can but with a window.setTimeout(Update, 0); in order to be responsive.
