Software and hardware requirements of WebGL on Windows

I'm creating a desktop-only Windows application and will use Electron, which uses Chromium. Chromium supports WebGL 2. I've read that WebGL on Windows is translated to DirectX calls by the ANGLE library (so OpenGL is not used at all).

Is it true that on each GPU where WebGL 1 runs, then WebGL 2 will run too? What's the required DirectX version for WebGL 1 and WebGL 2?

No, you can see here that WebGL2 support is much less than WebGL1 support – gman
Yes, I saw that before, but these statistics include different browsers, right? So IE, Edge, Safari and others will decrease percentage. I'm interested only in Chrome on WIndows (sorry, I didn't mentioned WIndows in my question). – HankMoody
You can drill down to just Chrome on Windows on that site. IIRC WebGL2 support in Electron requires at least DirectX 11 support at some certain version. Also, at least in Chromium there is a blacklist of drivers that are known to have bugs. You can turn off that blacklist in Electron and it will be up to you to workaround whatever bugs you find. – gman
@gman Oh, I didn't noticed the filtering option, it's very useful, thank you! Do you also know if the blacklist is the same for WebGL2, or there is a separate blacklist maybe? – HankMoody

of course not. each version requires different extension impl on GPU, need to be checked separately. for example try http://webglreport.com/ what ext for each version requires.

No, Your hardware/drivers needs to support the appropriate opengl version:

  • WebGL 1.0 exposes the OpenGL ES 2.0 feature set;
  • WebGL 2.0 exposes the OpenGL ES 3.0 API.

So if your hardware only supports OpenGL ES 2.0, webgl2 won't run.
