I captured this with all settings on or set to Ultra at a 720p resolution at 60 FPS and was able to eliminate any noticeable in-game performance hit by outputting raw footage to 3 SSDs. Regardless, frame rate hits are still enormous during large engagements, firstworldproblemsetc.
Running this on an i7 3820 @ 4.0GHz, an overclocked GTX 690, 16GB of Kingston HyperX 1600MHz DDR3 RAM and with the game installed to a RAM disk, frame rates peak as high as the mid one hundreds and as low as the twenties, averaging out in the high fifties. I hear performance optimisations relevant here happen mostly towards the end of a game's development, so I'm hopeful and optimistic performance will be improved by twelvetwelvetwelve!
