Crysis 2 First Pinger Fight
I recorded myself fighting the Pinger with an emphasis on action-packed spraying and explosions. The difficult is the second highest and I'm recording with FRAPS at 1080p, highest settings (I think)
I've found that the framerate hit of using FRAPS is much lower if you record to a hard-drive separate from the one the game is installed on.
My GPU was an AMD HD4870X2. It's very fast, but its drivers are beginning to break for newer games
