I did some extensive searching to see if I could find a direct answer, but I could not. I apologize if this topic has already been discussed.
Why exactly do 30FPS games judder? It was my understanding that 24fps Blu-rays judder because 24 is not an even multiple of 60 (aka 60/24= 2.5). 60FPS games will not judder because obviously 60 is an even multiple of 60. 30FPS is an even multiple of 60 so why exactly does 30FPS judder? I have never understood this. I am probably misunderstanding how this works. I would appreciate any insight!
