Can Device Farm Desktop browsers support WebGL 2.0?

Question

Hi!  I'm trying to set up automated QA for a Unity WebGL product, but when we build it with the WebGL 2.0 graphics API, and load our test page in Device Farm with Firefox,  we get the following error:

```
UnexpectedAlertOpenError: Dismissed user prompt dialog: Your browser does not support graphics API "WebGL 2.0" which is required for this content.
```

The latest Firefox definitely supports WebGL 2.0 at this point, so I'm assuming that Device Farm is turning it off intentionally, and I can't find any Selenium WebDriver commands to affect it either way.

So: is there some way to enable it, or will we be forced to use a different solution for our testing?

Hello,

This is Tom from AWS Support Team. I see that this is a question on WebGL 2.0 compatibility with Device Farm Desktop Browsers (Firefox).

Device Farm desktop browser instances are based on the c5.large instance type [1]. This type of EC2 instances does not offer GPUs, and thus use the CPU for all graphical computations. As a result, graphics-intensive applications such as those from Unity may not work as expected. Therefore, I would recommend alternative solutions for testing builds with WebGL 2.0 API integrations.

I hope the above information helps. Have a nice day!
