If you have a GeForce card, the "Experience" overlay gives you the option to use a much less intrusive counter. I'm guessing other cards have similar packages. I also use the overlay for screenshots and video. I no longer have to go into my FSScreen folder and convert bitmaps to jpeg, which is a major time saver!
Thanks, gents, for the info. I was not aware of the geforce software. Is the "Experience" the name of the program? I suppose it's available as a free download from nvidia.
