I got a quandary. A monitor working on a 60hz refresh rate will update the screen every 16ms. If you have a monitor with a 2ms response time, it will "update" the pixels pretty fricken fast... but then it has to wait an intolerably long time for a new frame from the frame buffer. So if people don't notice that long wait for the VRR signal, in "fast" games, how can they notice the difference between a 2 ms RT and an 8 or a 12 even, as omega said?
I just regurgitated what everyone else said, but with abit of amalgamated mouth noises (on a forum?). Yeah, I'm happy with this post.
