Understanding Hardware Acceleration on Mobile Browsers


Comments are closed.

Great overview on how GPU is used in browser rendering. I like how you have examples to demonstrate situations where GPU can be used (e.g. animation of a box sliding across the screen) and cannot be used (e.g. changing border width).

On the animation there was a number that counts the redraws, but I wasn't sure how that got updated. Will be great if you can explain how that works, and show a few other tools to debug whether GPU acceleration is active or not.
