I was using MSI Afterburner and I can display everything on the screen like cpu temp and gpu temp but it won't let me show the fps and I'm not sure why.
Does it say in MSI afterburner that it will display fps? Also, if it does, have you tested in-game? If neither of these work just screw around in afterburner a bit more. I am sorry I cannot be more helpful; I have never used the software myself.
