300 000 sprites, i5 2500, R9 270, Windows 8<p>- Chrome 44: 60 FPS constant<p>- Firefox 39: 49 FPS<p>- Firefox 40: 59-60 FPS<p>- IE 11: 10-12 FPS, very poor.<p>The FPS counter doesn&#x27;t appear on my smartphone (falcon, CM12.1 Browser), but i would estimate the performance is at about 10-15FPS at the <i>default</i> number of sprites, let alone the full 300 000.
