Why? i mean i am almost 100% certain Horizon Zero Dawn is 60fps and never ever have i had any issues.
Witcher 3 is suppose to get a Pro patch also, not sure if it is for framerate or what.

Anyhow, i have FFXIV set to the 2nd option (for 4k TV) and it sure does look nice, only thing now is the text and all that is so damn small, lol.
Tomorrow if i could even get back on i will test the other mode
