Resolution scale threshold for 4k

I don't understand this setting, would nice if someone could explain it to me, because Google wasn't a help here.

What should I set this to for the most games to work properly? I have the feeling most games don't scale right. Right now, this is set to 68 x 68.
I have a Ryzen 7 5700x, 32 gb of ram and a rtx 4070.

Thanks.

Resolution Scale Threshold has nothing to do with the used resolution scale value, hover the mouse over the setting to read what it does, it sets the minimum texture original size value to render at higher resolution, to prevent graphical issues.
