I wrote to AMD about this, and they told me that Relive and Overlay are not supported for mobility graphics. Seems a little counterintuitive to me. Surely if you are the sort of customer who pays extra for discrete graphics you'd be interested in gaming, streaming and monitoring your fps etc. These features work with APU integrated graphics after all. My question is - does anyone have an idea if and when AMD plans to incorporate these features for discrete graphics?
No unfortunately not. I have only ever heard that they are not supported. Not sure why it is not possible. Lots of smart folks here. Someone will likely know why not.
