Thanks for the link about Vega, JAB. There's some very interesting reading there and it provides a look at what browser developers go through.
The hardware back-end of Vega will unfortunately not work on all graphics cards. The good news is that we detect at runtime if your graphics card is supported or not and fallback to the software back-end of Vega if the graphics card is not supported. This means that everything will work regardless of your graphics cards capabilities.
