get the sources from git, type 'man patch' to read how to apply the patch to the sources, then compile and install.

If you have no idea what I just wrote, then leave it at that before you trash your system

probably no better than sticking to the integrated GPU in the first place.

If both GPUs differ in capabilities (ogl extensions etc), apps need to be restarted anyway since there's no good way to tell an app to stop using an extension while it's running.

Can Windows switch GPUs while 3rd-party 3D apps are running? I'd be surprised if that worked.
