Playing on a LG CX with hdmi 2.1 and OMG do the games that support 120fps mode suck ass.... it’s not constant 120fps it’s up to 120...more like averaging 80fps.
this is so disappointing that they can’t even find setttings on console for this framerate.
Force it to 1440p instead
Untick 'Allow 4K' in advanced options and select 1440p as your resolution.
