It is still in the driver but there were some hacked drivers which used to work until NVIDIA sued the developers. See my main rig, it has an NVIDIA card for Physx because it used to work.
Once NVIDIA moved to the APEX framework is when they simultaneously sued the physx hacked driver developer. NVIDIA has tried everything in order to stop AMD users from being able to enjoy PhysX. They even claimed that using an AMD card would result in a reduced gaming experience, false of course.

To me, that is all that matters.
While the idea of having BOTH an AMD and nVidia card in the same box is "cute", I don't see the real advantage.
Who will Crossfire/SLI work? Will it only be as good as the worst driver? What if one card has a profile for game x, but the other card doesn't? How will Crossfire perform in non-Full Screen mode? (Crossfire DOESN'T work, but SLI does a little, so what will happen?)
But to me, the biggest point is ... who is really going to go out and get a G-Sync AND FreeSync monitor? I mean I do, but only because I'm insane, but I really don't see people buying one of each. Then there is the whole issue of how G-Sync/FreeSync performs in a dual manufacturer card situation.
I'm sorry, I just don't see an advantage of doing this as opposed to picking a side and getting 2 cards.
There are no profiles. Multi adapter is implemented by the developer. It is not controlled by the driver or a driver profile. Basically the developer assigns alternating workloads, in the case of AFR, from one GPU to the other. I believe that fencing is used, in an alternating fashion, in order to achieve this.
There is no need for crossfire or sli profiles under DX12. In fact they don't work. This is truer for AMD than NVIDIA on the basis that the software, game, speaks directly to the hardware. The driver works as a minimal middle man who simply relays the information. With NVIDIA, it's a tad different because of their software side scheduling.
As fot Freesync/adaptive sync... NVIDIA supports the technology on laptops therefore their hardware supports it. Were you aware that "GSYNC", on laptops, is actually adaptive sync?Edited by Mahigan - 10/27/15 at 4:46am
