MOH is based on the Unreal3 Engine and has frame smoothing which has a max and min fps.This is setup in the ini files (pretty sure they didn't implement it into the frontend).You can disable the fps cap to benchmark I guess (change bSmoothFrameRate=TRUE to bSmoothFrameRate=FALSE) but it seems like the game runs best with this cap on.On UT3 people changed the max/min values depending on the systems tho and I have changed mine.As you seem to have a good system it might be worth putting the max up a little.Config:My Documents\EA Games\Medal of Honor\Config\MOHAEngine.ini
Code:
[Engine.GameEngine]bSmoothFrameRate=TRUEMinSmoothedFrameRate=32.000000MaxSmoothedFrameRate=62.000000
^^ that's mine, tweaked the min a bit as it drops stuff if you go below the min in an effort to smooth the framerate.You can take the cap off and check the fps I guess.A lot of people on UT3 used 85 as max, but I've also seen people on 220 or higher.I've not really checked my fps (would guess you'd use fraps or some type of overlay??) as I'm not sure if PunkBuster would pick it up as a cheat?Also make sure vsync is off if u want it over 60fps

Go careful with tearing also, can get annoying if u get tearing but I've not experienced it on UT3 with fps above 60 so should be ok.I've not played Black Ops but it seems to be based on an edited Quake3 engine (like cod4) so would guess it would have a cvar like com_maxfps (providing vsync is off) which would change the maxfps
