120hz to 144hz is hugely apparent on an OLED. Those of you who can't tell these differences on a LCD can attribute some of that to the pixel response blur disguising the increase.
My C1 120hz to this AW 144hz was obvious. 120hz to 175hz is a significant jump in perceivable smoothness and clarity.
Exactly this. OLED pixels are so fast there is basically no blurring between frames to hide how low FPS 120 is. One big reason why I passed on the 42C2.
175 Hz on this OLED wrecks 120 Hz OLED.
