I never understood why people said this.
I upgraded to a 144hz monitor not too long ago, from a 60hz monitor and I genuinely didn’t think it would be as smooth as it is. It’s something that you can’t really comprehend until you’ve tried it, especially if you’ve been at 60hz forever.
Even from 60fps, to 100fps, the difference is pretty drastic.
The human eye can see extremely high frame rates, but most say that you wont really be able to tell the difference past like 250fps.
Having a higher refresh rate is so much better for fps games, and literally gives you an advantage. So anyone who wants to take the game seriously, and says it’s a waste of money, is straight up lying. Unless of course, you can’t afford it, then just stick with what you got. It’s not essential, but it’s certainly very nice.
