M17x R4 780M and Optimus

This 780M I got my hands on is great. To be honest, I don't actually notice much of a difference compared to the 680M I was using previously. But still, it's nice.

Unfortunately, the 780M upgrade cost me Optimus. A feature I really liked :(

From what I understand there is no way to have Optimus operating inside a system that has a GPU outside of its OEM designated cards due to Optimus only activating in pre-designated device IDs.

Is this still the case today? If possible, I'd really like to figure a way to get Optimus back. Fn-F7 reboot really kills the mood :\

I though optimus would work as long as the iGP is not disabled in BIOS. EGPU users rely on optimus for a major performance increase so the device ID requirement thing sounds weird.

If device ID does matter maybe just edit the vBIOS to the 680m device ID?
