WebGL detection not accurate #34

Closed pbscreativeben closed 7 years ago

pbscreativeben commented 7 years ago

Hi,

Stumbled across this online while researching WebGL compatibility.

I am unable to view WebGL content in Chrome but your detection reports that my browser supports WebGL.

For example, in Chrome, on https://get.webgl.org/ the box does not spin but I get the 'Your browser supports WebGL' message. Similarly, Youtube 360 degree videos do not work either; both work in FF and Edge.

To get the WebGL content to work I can enable Chrome setting: Override software rendering list - Overrides the built-in software rendering list and enables GPU acceleration on unsupported system configurations. #ignore-gpu-blacklist

I am working on the assumption that although Chrome supports WebGL, my GPU is blacklisted.

Any insights into detecting this? Ideally I'd like to be able to detect this so I can degrade content gracefully for my web users who don't actually have WebGL support.

I suspect you are right about the blacklisted GPU.

Your best bet is probably to ask here: https://groups.google.com/forum/#!forum/webgl-dev-list

Let us know if the WebGL Report requires any changes, in the meantime I am going to close this issue.
