Fastest browser engine by far at 500 FPS! Servo Webrender - CSS on the GPU part 1: Rust

If you have the time there is a nice talk about WebRender: [VIDEO] Here is another great talk: [LINK] At ~25:30 he'll also talk a bit about Quantum. In a nutshell WebRender is used to send a web page to the GPU which will paint all divs, borders, shadows, images etc. Currently WebRender is the only component I'm aware of that is inside Firefox Nightly. It's still behind a config though.

In fact Mozillians are currently working on a new rendering pipeline[1] based on state of the art rendering tools[2]. This new pipeline should be deployed in firefox in 2018 as a part of the ongoing Quantum project. [1] [LINK] [2] [VIDEO]

I'm sure the future blog posts will have more details, but it has to do with immediate mode vs retained mode APIs. [VIDEO]

According to this: [VIDEO] Firefox's servo engine can compose CSS elements/Display List together at 500 frames / second. Maybe next version of Windows / Linux desktop should use FF's servo engine?
