Thanks so much for that! I'm glad to hear that the GLES2 fallback is working for you.
Godot's GLES3 renderer requires OpenGL 3.3 apparently, and it looks like the HD 3000 chipset only supports 3.0 on Windows (it's 3.3 if you're on Linux or MacOS \o/ ). So far as I can tell at the moment, this requirement doesn't appear to have changed since the initial release of Godot 3.0.
There is a setting for enabling that fallback by default, but I've never touched it and it's currently off. Perhaps falling back to that automatically was enabled by default in older versions of the engine. I'll set that to be enabled in future builds of the game.
