You have a point there but somehow I never managed to overcome the thought why to use an external (additional) SW for something the game already has inside the main core.
Two other points that spoke against it in the old IL2FB days (I am also of the OldSchool '66) was that I needed to see the average fps when I was benchmarking and
the fact that fps used to drop the frame rate.
I do not know what the fps overhead of FRAPS is nowadays, would be interesting to know.
Those days we used to squeeze every bit of our machines to go from 18fps to 21fps... if I read the posts here, I wonder sometimes...
I also admit, new to Win7 64bit (I installed it just for this game) I run CoD at low resolutions (1280x1024 while waiting for SLI to become available)
so I have much free space on my screen (3840x1024) and a lot of funny stuff open and it does not seem to have any impact at all so probably it would not matter.
But, as said, old habbits die hard
