theesh: Yeah, I tried Fraps. That seems to work just fine. Also tried the steam overlay, and that works dandy too. The only catch with steam is that GOG galaxy will not track time or achievements when the game is run through steam and not through galaxy.

Thanks for all the suggestions. Seems like Fraps, Dxtory, or the steam overlay. is the way to go until CDPR adds the screenshot functionality into the game.
