Hi. I have 2x4890 crossfire, driver 10.11 + newest catalyst game profiles. In some games ( New Vegas, Singularity,...) crossfire just doesn't work, one card is idle, so i get funny gameplay. so I rename the *.exe file of the game to Mafia2.exe, thus forcing crossfire. This works for me very nice.
Will I see different performance using different file name (ex. Metro2033, Crysis.exe...) ? Or is this trick only used to that the cards start working in crossfire ?
