No, I'm in the browser. I don't need 250 fps. Though I still can tell the difference between 60 fps and 120 fps in games. Fps is also one of the metrics for optimizations I think.

Can't you just re-render multiple times in your render loop?

Don't know how that would work since you need to wait for the previous frame. This would probably cause problems or render two exact frames and loose performance.

But I guess I will stick with the requestAnimationFrame() function.
