Servo is not a "display engine". The term is "rendering engine", but that's an inaccurate bit of terminology, most of what a rendering engine does doesn't actually deal with rendering. A better term is "browser engine". Parsing, styling, the DOM, running JS, handling networking, computing layout are all things that a browser engine does that don't involve rendering. Many of these can't be done on the GPU, and for others the GPU brings no additional benefit because it's not the kind of load the GPU can magically parallelize. Servo's rendering stack does make extensive use of the GPU. https://github.com/servo/webrender/ https://github.com/servo/webrender/ (talk by patrick in https://air.mozilla.org/bay-area-rust-meetup-february-2016/ https://air.mozilla.org/bay-area-rust-meetup-february-2016/) There's also work on glyph rasterization on the GPU going on right now.
