For me this has been one of the best drivers in a very long time. I've only played Tomb Raider 2013 and Battlefield 4. Also watched some movies on Netflix in 4K. Everything looks great and plays smooth! For me the RGB full is a HUGE difference in picture quality. True it allows alot more blacks while gaming but once I got used to it I love it. I'm aware that my Sony XBR doesnt produce the best blacks out there. I learned this from AVS forums. However, it makes the colors look much better and richer for me. I do switch it back to limited color when watching Netflix. I'm pretty sure native dvd's/blurays are best played back at YcBcR444 which the control panel changes to automatically in the driver for video playback?
