I dont know how to use specific game ones. Im using the control panel method, I believe what you are talking about involves nvidia inspector and is more complicated?
It's just a matter of copying and pasting a single line. Select the FEAR profile and copy this:
SLI compatibility bits (DX1x) said:0x000202F5 (F.E.A.R. 3)
Then paste it into the same section in Mordor's profile.

Seems likely. There will probably be a GOG exclusivity period, though.
