Chrome&#x27;s approach is fundamentally different: it&#x27;s the main difference I was describing at the beginning of the talk, by contrasting Chrome&#x27;s immediate mode approach with WebRender&#x27;s retained mode. (By the way, Safari, IE 9 and up, and Firefox on Vista and up all use immediate mode GPU painting backends like Chrome does.)<p>Incidentally, I don&#x27;t deserve the lion&#x27;s share of the credit here. Veteran game developer Glenn Watson is really the brains behind the project—my role has mostly consisted of picking off a few scattered features and optimizations to implement.
