What do you do with such users of your websites that will running your cool WEBGL application but has:
1) a graphic card that is not correctly supported in your browser ?
2) a graphic card that is only supported when he update the driver of his card ?
3) a graphic card that can not running WebGL ?
For all this tasks you need some analysis software that runs on your platform or/and at best on your browser. And this software should usable for non IT user. I'm only aware for example GPUZ on Windows. This analyse the GPU, but it doesn't solve all needed tasks. And the most of us knows http://get.webgl.org/ .
How do you handle this situations ? Or do you have any ideas about it ?
