Lunacidedownpourif you cant maintain 120fps, dont get a 120Hz monitor
thats it
I always heard that you need to maintain 240fps to get the full effect of the 120hz, is that true?
Sort of. I can notice when I go under 240. Can you notice when you go under 120 at 60Hz? If so, you'll probably notice it when you go under 240 at 120Hz.
If you need a new monitor and want a nice one, might as well get a 120hz (or THE 120Hz right now, since afaik there is only one good one). Or get one if you have gobs of money. It's not going to make you a god, it is just a bit smoother. You can actually see scouts' legs move when they ADADADAD hard.
Also pretty sure the BenQ monitor already has something pretty similar to lightboost on it already, but I didn't really look to much into that.
