The last months Opera 12 snapshots have received two major updates of its JavaScript engine, Carakan, which make it more memory efficient and fully ECMAScript 5.1 compliant. Last week the new HTML 5 parser Ragnarök was added. Today Opera 12 alpha introduces another major technological milestone: full hardware acceleration with WebGL.

Full hardware acceleration
Opera aims to give the best possible performance for all users. This is why we already have a "software accelerated" backend in Vega. However with the new hardware accelerated backend Opera will draw the whole user interface using the GPU, not just specific elements of the webpage like the canvas element. This will offload the CPU significantly and make it possible to accelerate the rendering of all webpages. On systems with outdated drivers or buggy graphics cards, Opera will fallback to the heavily optimized Vega software rendering engine.
