what do you mean? AMD integrated graphics are supported by the same open source driver... IIRC, anything that's GCN 1.2 or newer is supported (APU or dedicated)
Supported doesn't mean they are at the same feature level as fxgl used to be.
I am still waiting for OpenGL 4.1, the extensions listed here, and hardware video decoding, because from where I sitting glxinfo still reports OpenGL 3.0
You are correct - older hardware has suboptimal support. However - that laptop is at least eight years old. All the AMD graphics cards since Polaris have good support.
