Titan x certainly looks smoother in most of these comparisons.
Could you add the frame latency reading as well please greg. imo it is a better reading than FPS + it gives people an idea of "smoothness", anything below 20ms is smooth where as over 20ms, you notice the micro stutter.
I could do a few fraps recording with frame times if that would help? A really good idea Nexus as well cheers bud and quite agree about frame times being very important.
