Hi, Since EFL supports cairo, we compared EFL-TyGL and EFL-Cairo
* Canvas-performance: 1.7 times faster with TyGL (21 tests run correctly from 23 tests) Site: http://flashcanvas.net/examples/dl.dropbox.com/u/1865210/mindcat/canvas_perf.html * Asteroids-benchmark: 3.4 times faster with TyGL (4 tests run correctly from 6 tests) Site: http://www.kevs3d.co.uk/dev/asteroidsbench/ Regards, Zoltan > How does TyGL perform compared to the other rasterizers? > > What benchmarks do you use to guide the performance work? > > On 11/12/14, 11:12 PM, Zoltan Herczeg wrote: >> Hi All, >> >> We are proud to announce the TyGL port (link: >> http://github.com/szeged/TyGL) on the top of EFL-WebKit.
