Fraps does this I believe.
Is it possible to make a program that makes it where you can hold a hotkey to cap your fps? Like Bandicam you can hotkey, but that's toggle on and off. Is it possible to make one where you can hold the key? Or could someone even tell me if there's a program where you can hold a key or hotkey to record @ a certain fps? That'd be nice too.
